U.S. Customs and Border Protection is moving into a decisive phase of its quantum preparedness program as it approaches 2026. Senior leadership has framed this effort as a necessary response to long-term cryptographic risk rather than a speculative research exercise. The focus centers on protecting sensitive government data against future cryptanalytic breakthroughs tied to large-scale quantum computing, with post-quantum cryptography positioned as a core defensive control.
CBP’s role as a border security and law enforcement agency places it at the center of high-value data flows. These include biometric identifiers, traveler records, targeting intelligence, law-enforcement communications, and interagency operational data. Much of this information retains sensitivity for decades, making it vulnerable to “harvest now, decrypt later” collection strategies already used by advanced adversaries.
Post-Quantum Cryptography as a Defensive Baseline
CBP began structured post-quantum cryptography work several years ago in coordination with federal partners, including NIST. That early alignment matters. Quantum-resistant algorithms introduce changes across key management, certificate lifecycles, authentication protocols, VPN architectures, and embedded systems. Migration timelines in large enterprises often stretch across many years, especially in environments with legacy infrastructure and mission-critical uptime requirements.
Quantum-capable adversaries would be able to undermine widely deployed public-key systems such as RSA and ECC through Shor’s algorithm. That outcome would collapse trust in digital signatures, TLS sessions, secure email, software update chains, and identity systems that rely on asymmetric cryptography. For a federal agency with global data exchange and persistent intelligence value, exposure would not begin at the moment quantum machines mature; it already exists through silent collection of encrypted traffic.
CBP’s stated objective of preventing data harvesting signals a shift from passive readiness to proactive cryptographic hardening. Deploying NIST-selected PQC algorithms at scale reduces the future payoff of intercepted data, even if quantum computing advances faster than projected.
Enterprise-Scale Implications for Federal Infrastructure
Post-quantum migration is not a single technology swap. It forces changes across hardware security modules, smart cards, mobile devices, IoT endpoints, cloud services, and partner integrations. Key sizes increase, performance profiles change, and some constrained environments face non-trivial engineering tradeoffs.
CBP’s approach suggests recognition that cryptographic agility must become an architectural property rather than a compliance checkbox. Systems designed to rotate algorithms, certificates, and trust anchors without service disruption place agencies in a stronger defensive position as standards continue to evolve.
Operational Uses of Quantum Computing
Beyond defensive cryptography, CBP is also moving toward limited operational use of quantum computing for optimization problems. Access to a quantum computer for experimental workloads allows exploration of areas where classical methods struggle with combinatorial complexity.
One cited application involves optimizing communications tower placement to improve data exchange with agents and officers in the field. These problems involve terrain modeling, signal propagation, coverage overlap, and redundancy constraints. Quantum optimization techniques may offer performance gains in evaluating large solution spaces, even at current hardware maturity levels.
CBP has also referenced movement away from flat, two-dimensional network planning models toward three-dimensional analysis for line-of-sight communications. That shift reflects a broader trend in mission networks, where spatial awareness, environmental modeling, and dynamic topology analysis improve reliability in contested or remote environments.
Security Drivers Behind the Timeline
Quantum readiness is being framed as a race against adversary adaptation rather than a distant research milestone. Nation-state intelligence services and transnational criminal groups already invest heavily in long-term data collection. Cryptographic transitions that wait for visible quantum breakthroughs arrive too late to protect historical data.
Federal agencies face added pressure due to statutory data retention requirements, cross-border information sharing, and dependence on commercial technology stacks that change slowly. Early movement toward PQC creates time to test interoperability, performance impact, and failure modes before adoption becomes mandatory across government.
A Shift in Federal Technology Posture
CBP leadership has characterized its approach as moving away from incremental modernization toward faster, more decisive change. Quantum technology acts as a forcing function for that posture. It touches security architecture, network engineering, vendor relationships, and workforce skill sets at once.
As 2026 approaches, CBP’s progress will likely serve as a reference model for other federal entities assessing how to integrate quantum-resistant security controls and selective quantum computing use into operational environments without waiting for crisis-driven mandates.

A rootkit is a class of post-exploitation malware built to preserve long-term, privileged access to a compromised system while actively concealing its presence. Unlike most malware families that prioritize immediate payload execution or data theft, a rootkit exists to subvert visibility itself. It alters how an operating system reports processes, files, memory, network activity, and security events, allowing attackers to operate inside an environment without triggering normal detection mechanisms.
Rootkits achieve this by interfering with trusted system components. These include kernel subsystems, bootloaders, firmware interfaces, shared libraries, and virtualization layers. Once installed, a rootkit can mask secondary malware, suppress security tooling, interfere with logs, and reestablish attacker access even after partial remediation. Their value lies in dwell time. Rootkits give adversaries the space needed to stage follow-on actions such as credential theft, lateral movement, ransomware deployment, or espionage.
Rootkits as a Post-Exploitation Capability
A rootkit is not an initial access mechanism. It does not deliver itself through phishing or exploit chains in isolation. Its role begins after compromise, once an attacker has achieved administrative or kernel-level execution. At that stage, the rootkit becomes an infrastructure component for the intrusion rather than the intrusion itself.
Within MITRE ATT&CK, rootkit activity maps to defense evasion and persistence techniques. T1014 (Rootkit) captures kernel- and user-space manipulation, while T1542.003 (Bootkit) reflects compromise of the boot process. These techniques often reinforce others such as process injection, credential dumping, scheduled task abuse, or covert command-and-control staging. In practice, the rootkit is the layer that keeps those behaviors hidden.
Terminology and Placement
The term “rootkit” is often used broadly, though it covers several distinct implementations based on execution depth. Bootkits operate before the operating system loads. Kernel-mode rootkits execute inside ring 0. Firmware implants reside below the OS entirely. Hypervisor rootkits insert themselves beneath the guest operating system using virtualization features. User-mode rootkits remain in process space and manipulate APIs or shared libraries.
These are not interchangeable from a detection or response perspective. Each location represents a different trust boundary and a different failure point for defensive tooling.
Historical Development
Early rootkits emerged in Unix environments during the 1990s. They modified userland utilities such as ps, ls, and netstat so malicious processes or network connections would never be displayed. Defensive tooling adapted, which forced attackers deeper into the operating system.
Kernel-level rootkits followed, intercepting system calls directly rather than modifying binaries. This removed reliance on disk artifacts and bypassed integrity checks. Modern variants extend even further. UEFI rootkits execute before the kernel and survive OS reinstallation. Hypervisor rootkits exploit hardware virtualization to monitor and manipulate a system from outside the guest OS. Cloud-oriented rootkits embed persistence into container runtimes, shared images, or orchestration layers where endpoint tooling has limited reach.
As infrastructure moved toward ephemeral workloads and abstracted platforms, visibility gaps widened. Rootkits exploit those gaps.
Rootkit Taxonomy
User-Mode Rootkits
User-mode rootkits execute inside normal process space. They hook application programming interfaces, replace shared libraries, or inject code into trusted services. Their purpose is output manipulation. File listings, registry queries, process enumeration, and network calls are filtered before reaching security tools.
Deployment is relatively simple and does not require kernel exploits. Detection is more achievable with mature EDR telemetry and memory inspection, though they still evade basic monitoring.
Kernel-Mode Rootkits
Kernel rootkits operate inside the OS kernel and override core functionality. They hook system call tables, patch kernel modules, or register malicious drivers. From this position, they can hide processes, sockets, files, and even security agents themselves.
On Windows, these rootkits often abuse signed drivers or exploit kernel vulnerabilities to bypass enforcement. On Linux, malicious loadable kernel modules override functions such as readdir() or /proc enumeration. Stability and persistence increase sharply at this layer.
Bootkits
Bootkits compromise the bootloader and execute before the kernel initializes. Their code runs at startup, patches kernel memory, and launches secondary payloads long before endpoint agents load. Disk-based scans and OS reinstallations do not remove them unless boot records are fully rewritten.
Bootkits often appear alongside firmware manipulation or disk encryption abuse in advanced intrusion sets.
Firmware Rootkits
Firmware rootkits infect BIOS, UEFI, or embedded device firmware. They reside outside the operating system and reintroduce malware during every boot cycle. Visibility from the OS is effectively nonexistent.
Remediation requires hardware reflashing with verified images. Several publicly documented campaigns have demonstrated firmware implants used for espionage, particularly in long-term access operations.
Hypervisor Rootkits
Hypervisor rootkits leverage hardware virtualization to insert a malicious layer beneath the operating system. The target OS runs as a guest, unaware that execution is being monitored and modified. All activity becomes observable and alterable by the attacker.
Detection from within the guest is extremely difficult. Telemetry must come from the host, firmware, or hardware attestation layers.
Library and Runtime Rootkits
Library rootkits replace or hijack shared system libraries. On Linux, LD_PRELOAD abuse is common. On Windows, system DLL replacement or sideloading achieves similar outcomes. These rootkits alter program behavior without modifying the kernel, often filtering outputs or redirecting execution paths.
Cloud and Container Rootkits
In cloud-native environments, rootkit functionality is embedded into container images, init containers, daemonsets, or node-level services. Persistence is achieved through orchestration mechanisms rather than traditional startup paths. Some attacks rely on permissive IAM roles rather than local privilege escalation.
Visibility is complicated by shared infrastructure and transient workloads.
Installation and Execution Flow
Rootkits require elevated execution. Attackers obtain this through credential abuse, kernel exploits, signed driver misuse, or supply chain compromise. Once privileges are available, the rootkit modifies system behavior at its chosen layer.
On Windows systems, kernel rootkits hook SSDT entries or register malicious drivers. On Linux, kernel modules override filesystem and process enumeration functions. Firmware rootkits write directly to flash regions. Hypervisor rootkits manipulate virtualization extensions.
Once active, the rootkit’s first priority is concealment. Secondary tooling is then deployed under its protection.
Role in the Attack Lifecycle
Rootkits appear after initial access and privilege escalation. Their presence marks a transition from intrusion to occupation. They cloak lateral movement tooling, credential access activity, tunneling utilities, and data staging operations.
In ransomware campaigns, rootkits delay detection and interfere with response tooling. In espionage operations, they suppress audit trails and extend dwell time. In cryptomining cases, they hide resource consumption and block security agents.
Their value lies in persistence and deception rather than payload execution.
Detection Challenges and Indicators
Rootkits target the mechanisms defenders trust. Logs disappear. Processes fail to enumerate. Drivers load without visibility. Detection relies on identifying inconsistencies rather than signatures.
On Windows systems, unregistered kernel drivers, resource consumption without visible processes, and conflicting registry query results raise concern. On Linux systems, discrepancies between raw disk views and directory listings, missing processes in ps that appear in /proc, or abnormal syscall table entries are common indicators.
Memory analysis is often required. Rootkits unlink themselves from standard enumeration paths. Volatile memory still contains overwritten pointers, rogue kernel objects, and injected code.
SIEM and XDR platforms should correlate telemetry across layers. Disk activity that lacks process lineage, network traffic from signed drivers, or kernel behavior that deviates from baseline merit investigation.
Memory Forensics and Rootkit Exposure
When disk and runtime telemetry fail, memory remains the final source of truth. Kernel objects cannot fully erase themselves from RAM. Analysts use memory snapshots to identify hidden drivers, altered syscall tables, and direct kernel object manipulation artifacts.
Comparing in-memory structures to known-good kernel images exposes subversion that no log will show. Memory analysis demands skill and effort, though it remains one of the few reliable methods against advanced rootkits.
Prevention and Hardening Strategy
Rootkit defense begins below the operating system. Secure boot, driver enforcement, and firmware integrity controls are foundational. Unsigned kernel modules should be blocked. Firmware updates should be verified. Privileged access should be constrained and audited.
Endpoint tooling must extend into kernel telemetry and integrity monitoring. File integrity baselines, boot chain validation, and memory visibility reduce blind spots. In cloud environments, hardened base images, restricted IAM roles, and workload attestation limit persistence paths.
Reinstalling an operating system without validating firmware or boot components does not restore trust.
Incident Response for Rootkit Compromise
Suspected rootkit infections require containment without destroying evidence. Systems should be isolated but kept powered when possible to preserve volatile artifacts. Memory and disk acquisition should occur before remediation.
Trust must be rebuilt from verified sources. Bare-metal reinstallation, firmware reflashing, and image replacement are often required. In cloud environments, instances should be terminated and rebuilt from validated templates.
Root cause analysis must identify the privilege escalation vector that enabled installation. Without addressing that path, reinfection remains likely.
Engagement of specialized incident response teams is appropriate when firmware or hypervisor compromise is suspected.
Rootkit FAQs
How do rootkits remain hidden for long periods of time?
Rootkits remain hidden by altering how the operating system reports its own state. Rather than stopping security queries outright, many rootkits intercept and modify responses so that tools receive sanitized results. File listings omit malicious artifacts, process enumeration excludes attacker-controlled threads, and network utilities fail to show active connections. This approach preserves system stability and reduces the chance of user-visible failures that would prompt investigation.
At deeper levels, kernel and firmware rootkits modify internal data structures or execution paths so that monitoring tools rely on already-compromised information sources. Once visibility itself is corrupted, conventional detection loses reliability.
Why are rootkits difficult for EDR and antivirus tools to detect?
Most endpoint tools operate at the same or higher abstraction level than the operating system they monitor. A kernel-mode or firmware-level rootkit executes below those tools, allowing it to manipulate the data they depend on. If process lists, file metadata, or kernel callbacks are altered before EDR inspection occurs, the security tool observes a false representation of the system.
Signature-based detection also struggles since many rootkits use custom loaders, encrypted payloads, or legitimate signed drivers. Detection relies less on known indicators and more on behavioral inconsistencies across system layers.
What role does memory forensics play in rootkit detection?
Memory forensics provides visibility into execution state that disk and log analysis cannot offer. Even when a rootkit hides files, drivers, or services from the operating system, its code and modified kernel structures still exist in volatile memory. Analysts can identify discrepancies by reconstructing kernel object lists, inspecting syscall tables, and comparing in-memory structures to known-good baselines.
This technique is resource-intensive and requires specialized expertise, though it remains one of the few reliable options against advanced kernel and firmware rootkits.
What is Direct Kernel Object Manipulation (DKOM) in practical terms?
DKOM refers to the direct modification of kernel data structures in memory without using standard system APIs. A rootkit using DKOM may remove its process from linked lists that tools like Task Manager or ps rely on, even though the process continues executing normally. Network connections, drivers, and registry objects can be hidden using the same method.
Since no API calls are involved, security tools that monitor function usage or driver registration events often miss DKOM-based activity entirely.
Can a system be trusted after a rootkit infection?
Once a rootkit is confirmed, system trust is fundamentally broken. The operating system can no longer be assumed to report accurate information about its own state. Even if malware appears removed, hidden persistence mechanisms may still exist at the kernel, bootloader, or firmware level.
Restoring trust requires rebuilding from verified installation media and validating firmware integrity. In some cases, hardware replacement or firmware reflashing becomes necessary to eliminate residual risk.
Are rootkits used by cybercriminals or only nation-state actors?
Both groups use rootkits, though sophistication varies. Nation-state actors often deploy firmware or boot-level rootkits for long-term surveillance and reentry. Criminal groups tend to favor kernel-mode rootkits to hide credential theft tools, cryptominers, or ransomware staging activity. Public cases show sustained use across espionage, financially motivated attacks, and large botnet operations.
Rootkits no longer indicate exclusivity to advanced intelligence services. They represent a practical tool for any actor seeking extended dwell time.
What security controls reduce the risk of rootkit installation?
Controls that restrict privileged execution reduce exposure significantly. Enforcing secure boot, blocking unsigned drivers, limiting kernel module loading, and restricting firmware updates narrow the attack surface. Strong credential hygiene and least-privilege access reduce the likelihood that attackers can reach the execution level rootkits require.
Visibility below user space also matters. Kernel telemetry, boot-chain validation, integrity monitoring, and memory-aware detection increase the chance of identifying tampering before long-term persistence is established.

Featured Browser Extensions Caught Harvesting AI Chat Data at Scale
Actively Exploited WinRAR Flaw Draws Multiple APT Groups and CISA Action
How can Netizen help?
Featured Browser Extensions Caught Harvesting AI Chat Data at Scale
A Chrome browser extension promoted as a trusted, “Featured” tool has been caught quietly collecting AI chat conversations at massive scale, raising serious questions about extension marketplace oversight and user consent in AI-heavy workflows.
Urban VPN Proxy, a Chrome extension with roughly six million users and a 4.7-star rating, was found intercepting and exporting every prompt and response exchanged with major AI platforms. That includes ChatGPT, Claude, Copilot, Gemini, Grok, Meta AI, DeepSeek, and Perplexity. The same extension also reports more than 1.3 million installs on Microsoft Edge.
The behavior was introduced in version 5.5.0, released July 9, 2025. From that point forward, AI data harvesting was active by default, controlled through hard-coded settings rather than user configuration. Anyone using the extension for its advertised VPN functionality effectively received new surveillance code without meaningful notice or opt-in.
The technical mechanism is direct and difficult for users to observe. The extension injects platform-specific JavaScript files into AI chat sessions, including scripts such as chatgpt.js and gemini.js. Once active, those scripts override standard browser networking interfaces, intercepting both fetch() and XMLHttpRequest() calls. Every AI interaction is routed through the extension before being sent onward, allowing the full conversation to be captured.
Captured data includes user prompts, AI responses, session identifiers, timestamps, platform details, and related metadata. That information is then transmitted to remote infrastructure controlled by Urban VPN, including analytics and statistics endpoints under the company’s domain.
Koi Security, which disclosed the activity, noted the practical risk created by automatic extension updates. Users who installed Urban VPN months or years earlier for basic proxy services woke up to a version that harvested sensitive AI conversations without fresh consent or clear disclosure. From a security perspective, that change materially alters the threat profile of the extension.
Urban VPN’s privacy policy was updated shortly before the release, acknowledging that AI prompts and outputs are collected. The policy frames the practice as support for “safe browsing” and marketing analytics, claiming that data is filtered, de-identified, and aggregated. At the same time, the company concedes that sensitive information may still be processed and that complete removal of personal data cannot be guaranteed.
More concerning is the downstream data-sharing model. One of the listed recipients of collected browsing data is BIScience, an ad intelligence and brand monitoring firm that owns Urban Cyber Security Inc. The policy states that BIScience receives raw, non-anonymized data to generate commercial insights shared with business partners.
That relationship is not new. Earlier this year, independent researchers accused BIScience of collecting detailed clickstream data through third-party browser extensions under misleading disclosures. According to those findings, BIScience supplies SDKs to extension developers that funnel browsing data to infrastructure under its control, exploiting policy carve-outs in Chrome’s Limited Use requirements.
Urban VPN markets an “AI protection” feature that warns users when prompts contain personal data or when AI responses include suspicious links. The presentation suggests user safety controls. What it does not disclose is that AI conversation harvesting continues whether that feature is enabled or disabled.
As Koi Security described it, users receive warnings about sharing sensitive data with AI providers while the extension simultaneously sends that same data to its own servers for resale. From a risk standpoint, the protection messaging functions more as cover than control.
The issue extends beyond a single extension. Koi Security identified identical AI interception logic in three other tools published by the same developer: 1ClickVPN Proxy, Urban Browser Guard, and Urban Ad Blocker. Combined, those extensions account for more than eight million installs across Chrome and Edge. Most carry “Featured” badges, signaling platform endorsement and quality review.
That badge carries weight. For many users, it represents an implicit trust signal from Google or Microsoft. Security teams often treat featured extensions as lower risk during audits. This case shows how easily that trust can be abused.
The broader takeaway is not limited to Urban VPN. AI chat interfaces now sit at the center of sensitive workflows. Users draft legal language, troubleshoot production systems, discuss health concerns, and disclose internal business context through these tools. Browser extensions operate at exactly the layer where that data passes in clear view.
Actively Exploited WinRAR Flaw Draws Multiple APT Groups and CISA Action
CISA has added a WinRAR vulnerability to its Known Exploited Vulnerabilities catalog following confirmation that multiple threat groups are actively abusing the flaw in real-world attacks.
The issue, tracked as CVE-2025-6218 and rated 7.8 on the CVSS scale, is a path traversal vulnerability in WinRAR for Windows. Successful exploitation allows an attacker to place files outside the intended extraction directory, opening a path to unintended code execution under the current user’s context. Exploitation hinges on user interaction, typically through opening a malicious archive delivered via phishing or visiting a hostile webpage.
RARLAB addressed the vulnerability in WinRAR version 7.12, released in June 2025. Only Windows builds are affected. Unix-based and Android versions remain unaffected.
At a technical level, the flaw enables attackers to write files into sensitive locations such as the Windows Startup folder or application template paths. This behavior can establish persistence that triggers execution on system startup or during normal application use, without relying on exploits that immediately draw attention from endpoint defenses.
Multiple security firms, including BI.ZONE, Foresiet, SecPod, and Synaptic Security, have documented exploitation by at least three distinct threat groups. The campaigns show consistent use of phishing-delivered RAR archives and deliberate targeting rather than indiscriminate mass distribution.
One set of attacks has been attributed to the Russian-linked group tracked as GOFFEE, also known as Paper Werewolf. BI.ZONE reported that the group combined CVE-2025-6218 with another WinRAR path traversal flaw, CVE-2025-8088, during phishing campaigns observed in July 2025. The activity focused on organizations inside Russia and relied on carefully crafted archives to place malicious files in execution paths.
The vulnerability has also been weaponized by the South Asia-focused Bitter APT, tracked as APT-C-08 or Manlinghua. Foresiet’s analysis shows the group using malicious RAR files that include a legitimate Word document alongside a malicious macro template. During extraction, the archive drops a weaponized Normal.dotm file into Microsoft Word’s global template directory.
Normal.dotm loads automatically every time Word is opened. By replacing the legitimate template, the attacker achieves persistent macro execution without relying on subsequent phishing emails or user interaction. This approach bypasses many email-based macro defenses since the malicious behavior occurs after the initial compromise.
Once persistence is established, Bitter deploys a lightweight downloader that retrieves a C# trojan from external infrastructure hosted at johnfashionaccess[.]com. The payload supports keylogging, screenshot collection, credential harvesting from RDP sessions, and file exfiltration. Campaign telemetry suggests spear-phishing remains the primary delivery method.
CVE-2025-6218 has also appeared in campaigns attributed to Gamaredon, a Russian state-aligned group known for sustained operations against Ukrainian government and military entities. In activity first observed in November 2025, the group used malicious WinRAR archives to deploy malware known as Pteranodon.
Researchers assessing the campaign described it as deliberate and mission-focused, aligning with military-oriented intelligence collection and disruption rather than opportunistic cybercrime. Follow-on analysis shows Gamaredon also abusing CVE-2025-8088 to deploy Visual Basic Script malware and a destructive wiper dubbed GamaWiper.
ClearSky assessed this activity as the first confirmed instance of Gamaredon engaging in destructive operations rather than its traditional espionage-focused tradecraft. That shift increases the risk profile of unpatched systems, particularly inside government and defense environments.
Given confirmed exploitation, CISA has directed Federal Civilian Executive Branch agencies to remediate affected WinRAR installations by December 30, 2025. Organizations outside the federal space should treat the timeline as a practical benchmark rather than a compliance formality.

Attackers looking to move sideways inside a network increasingly treat shared file stores, on-prem SMB/CIFS shares, collaboration drives, and cloud file services, as low-risk highways for staging, discovery, and quiet data collection. These locations are attractive because they are widely trusted, broadly accessible, and rarely monitored closely enough to catch subtle behavior. Lateral movement through file shares lets an adversary expand access without noisy scans or obvious remote execution attempts, often succeeding long before defenders notice anything unusual.
How Threat Actors Use Shared Drives
Adversaries use shared drives in several ways. They drop reconnaissance tools, scripts, or encrypted archives into folders where service accounts or administrators will eventually access them. They hide tooling inside harmless-looking filenames or deeply nested folders and rely on routine user actions to trigger execution or movement. When cloud storage is available, attackers can shift staging and exfiltration into remote accounts under their control, which makes detection even more difficult. This fits into the broader pattern of living off trusted services instead of relying on noisy exploits.
Why Shared Drives Work Well for Quiet Lateral Movement
Shared drives are busy environments by design. Users copy files constantly, sync folders across devices, and run automated tasks that generate steady background noise. That noise makes it easy for attackers to hide small deviations, such as a new executable or a large archive dropping into a common folder. Weak permissions, legacy share configurations, and wide write access contribute to the problem. In hybrid environments, attackers can also pivot between on-prem shares and cloud collaboration drives, where trust models differ and oversight is inconsistent.
Common Techniques Observed
A typical attack path looks like this: foothold on a workstation, reconnaissance to locate writable or commonly accessed shares, staging of scripts or payloads, and then using legitimate processes, scheduled tasks, sync tools, backup software, or service accounts, to move code or credentials deeper into the environment. Credential theft often plays a supporting role. Once an attacker captures usable tokens or hashes, they can access more shares and deploy more staged tools without generating obvious red flags. Because the approach blends in with normal behavior, dwell time increases and response becomes harder.
Detection Challenges
Catching this activity is difficult because file creation, movement, and deletion events are high volume and rarely filtered with security in mind. Many environments forward these events into logging platforms without linking them to identity or process behavior, which reduces visibility and increases fatigue. Successful detection usually requires establishing baselines: who normally writes to a given share, which processes interact with shared folders, and how service accounts move across systems. Attack-path mapping also helps, since the relationships between identities, hosts, and shares often reveal the routes attackers prefer.
Practical Mitigations That Reduce Risk
Risk drops considerably when organizations strengthen access control, tighten permissions, and improve visibility around shared storage.
Start with access cleanup. Remove broad write rights, restrict legacy shares, and review service accounts that touch multiple systems. Enforce secure authentication where possible and, for cloud drives, monitor third-party app consents and permissions granted to automation tools. File integrity monitoring helps when paired with process and identity telemetry, because an unexpected write by a rarely used account or a desktop process writing archives to a server becomes much harder to overlook.
Combine this with attack-path analysis. Understanding how users, groups, and systems connect makes it easier to predict the lateral routes an attacker would choose. Treat shared drives as part of the identity surface rather than just storage, and aim for monitoring that ties file events to real user behavior. Tabletop exercises focused on file-based staging can uncover operational blind spots before a real attacker finds them.
What To Do When You Find Staging Artifacts
If you discover suspicious files or scripts on a shared drive, start with containment and context. Limit access to the affected share or narrow the permissions used to drop the artifact. Capture metadata, timestamps, ACLs, and the host that created or modified the file, and search for similar files across other shares. Check account activity around the time of the write and look for related scheduled tasks, process launches, or signs of credential misuse. Preserve evidence before cleaning anything up and coordinate with system owners to avoid breaking legitimate workflows. These steps help determine how far the attacker progressed and whether other systems have been touched.
Balancing Operations and Security
Hardening shared filesystems often requires cooperation across storage teams, identity teams, and security teams. Start with the highest-risk shares and accounts, and phase changes carefully so you don’t disrupt business operations. Improving telemetry and conducting regular threat hunts focused on file-based staging will shorten dwell time and reduce the chance that an attacker uses shared drives as a quiet highway through the network.

Zero Trust has become the organizing model for most modern security programs. At the same time, more organizations are moving to SOC as a Service because the operational load of running an in-house SOC, tuning content, maintaining coverage, hiring analysts, and responding at all hours, is increasingly unrealistic. The question most security leaders ask now is simple: where do these two strategies meet, and how does a managed SOC actually help an organization progress toward a Zero Trust architecture?
A Brief Foundation
Zero Trust rests on a core idea: nothing inside the environment is assumed safe, and every request for access is treated as a fresh decision based on identity, device posture, context, and risk signals. Network location offers no automatic trust. Access is only granted when enough evidence supports it, and that evidence must be re-evaluated continuously.
A managed SOC fits directly into that model because Zero Trust cannot function without ongoing visibility, correlation, and feedback. The architecture depends on the constant collection of logs, signals, and behaviors. It also depends on someone interpreting that data and using it to reinforce policies. That is where SOC as a Service operates best.
What SOC as a Service Actually Delivers
SOC as a Service replaces the traditional in-house security operations center with a cloud-delivered team responsible for continuous monitoring, detection, investigation, and response guidance. It removes the need for organizations to maintain a SIEM, staff analysts, or manage tooling pipelines. Instead, the provider handles:
Round-the-clock monitoring of infrastructure, endpoints, cloud services, identities, and applications.
Detection logic tuned to real attacker behaviors, supported by threat intelligence and behavioral analytics.
Human investigation of alerts to filter false positives and escalate only meaningful activity.
Guidance or hands-on assistance in containment actions.
This turns cybersecurity operations into an operating expense and removes most of the overhead associated with scaling a SOC internally.
How SOC as a Service Strengthens Zero Trust
Zero Trust is built on several pillars: identity, devices, networks, applications, and data. What ties them together is a continuous verification loop. SOC as a Service provides that loop.
Identity
Every Zero Trust program treats identity as the first control point. A managed SOC monitors authentication flows, MFA behavior, privileged account usage, and suspicious consent activity. Analysts can detect token theft, unusual login patterns, or abuse of service accounts. These events guide adjustments to conditional access policies, privilege boundaries, and identity governance controls.
Devices
Zero Trust expects devices to be healthy, monitored, and strongly attributed. SOCaaS providers rely on EDR or XDR telemetry to maintain a real-time view of host behavior: exploit attempts, persistence mechanisms, unexpected command execution, or lateral movement. These findings feed decisions about device trust levels and drive adjustments to posture-based access rules.
Networks
Zero Trust networking emphasizes microsegmentation and the reduction of lateral movement. A managed SOC watches internal flows, VPN activity, and unusual traversal between segments. When the SOC sees a suspicious pattern, an unmanaged host reaching into a sensitive subnet, or a workload attempting a direct database connection, it can recommend segmentation changes or closer boundary controls.
Applications and Workloads
Modern environments depend heavily on cloud workloads, containerized applications, and APIs. SOCaaS monitors logs from orchestration layers, serverless functions, WAFs, and API gateways. Analysts look for abuse of service accounts, unexpected API calls, or deviations in workload behavior. Those insights push teams to refine workload identity, strengthen application access policies, and correct misconfigurations exposed by real activity.
Data
The data pillar is where Zero Trust ultimately leads. A managed SOC correlates DLP activity, cloud storage access, database audit logs, and file access events with identity and device context. When patterns point to exfiltration or unauthorized aggregation, the SOC can recommend policy adjustments to narrow access or implement stricter controls on sensitive repositories.
Why SOC as a Service Accelerates Zero Trust Adoption
Zero Trust requires telemetry coverage, deep correlation, and continuous feedback. Those demands are exactly where organizations often struggle. SOCaaS fills that operational gap in several ways.
It provides the visibility foundation needed before any meaningful Zero Trust policy decisions can occur. Without consistent logging and analysis, Zero Trust devolves into guesswork.
It shortens the gap between detection and response. The whole idea of Zero Trust is built around the assumption that threats will get inside. Fast detection and containment support that mindset.
It turns incidents into policy improvements. Every confirmed alert reveals gaps: an identity with too much access, a segment too open, a workload too permissive. A managed SOC highlights these weaknesses and pushes teams to refine controls.
It supports automation. As detection patterns stabilize, playbooks can be developed so certain events trigger automated policy adjustments or isolation steps. SOCaaS providers often help organizations mature into these automated workflows.
Patterns That Help Programs Mature Faster
Organizations that successfully integrate SOC as a Service into their Zero Trust programs tend to follow a few predictable patterns.
They start with a mapping exercise, comparing their log and signal coverage to the Zero Trust pillars; the gaps usually show where the SOC needs more data.
They feed every investigation into policy refinement, rather than treating incidents as isolated tasks. This is the difference between an operational SOC and a Zero Trust SOC.
They align SOC workflows and SLAs with Zero Trust goals. If identity risk is the top priority, identity-related detections must be escalated differently than low-impact anomalies.
They address governance questions early: who owns tuning, what data gets retained, how automated actions are approved, and how findings feed into compliance and internal risk reporting.
Final View
Zero Trust depends on ongoing verification, adaptive controls, and the assumption that intrusions will occur. That model cannot function without continuous monitoring and interpretation of security data. SOC as a Service gives organizations a practical engine for that work. It closes operational gaps, accelerates maturity, and supplies the visibility and response capabilities that Zero Trust requires.
Without a managed SOC or an in-house equivalent, Zero Trust risks becoming a diagram instead of a functioning security model. With SOC as a Service in place, the architecture gains the real-time feedback and corrective pressure it needs to actually protect an organization.

Microsoft’s December 2025 Patch Tuesday includes fixes for 57 vulnerabilities, including one actively exploited zero-day and two publicly disclosed zero-days. Three of the patched flaws are classified as critical, all tied to remote code execution.
Breakdown of Vulnerabilities
28 Elevation of Privilege vulnerabilities
19 Remote Code Execution vulnerabilities
4 Information Disclosure vulnerabilities
3 Denial of Service vulnerabilities
2 Spoofing vulnerabilities
These totals do not include 15 Microsoft Edge vulnerabilities or Mariner fixes that were released earlier in the month. Non-security updates released alongside this cycle include Windows 11 KB5072033 and KB5071417.
Zero-Day Vulnerabilities
This month’s update addresses three zero-days, one of which has been actively exploited in real-world attacks.
CVE-2025-62221 | Windows Cloud Files Mini Filter Driver Elevation of Privilege Vulnerability
This actively exploited flaw stems from a use-after-free condition in the Windows Cloud Files Mini Filter Driver. Successful exploitation allows a local attacker to escalate privileges to SYSTEM. Microsoft attributes the discovery to the Microsoft Threat Intelligence Center and Microsoft Security Response Center but has not shared exploitation details.
CVE-2025-64671 | GitHub Copilot for JetBrains Remote Code Execution Vulnerability
This publicly disclosed vulnerability allows local command execution through improper neutralization of special elements in command handling. The issue can be triggered via a Cross Prompt Injection using untrusted files or malicious MCP servers, allowing attackers to append commands to those auto-approved in the terminal. The flaw was disclosed by Ari Marzuk as part of the “IDEsaster” research into AI-powered development tools.
This PowerShell vulnerability results from improper command handling when Invoke-WebRequest retrieves web content containing embedded scripts. Under certain conditions, those scripts could execute locally. Microsoft has added a new warning that prompts users to apply the -UseBasicParsing switch to prevent unintended script execution. Multiple researchers contributed to the discovery of this issue.
Other Critical Vulnerabilities
Beyond the zero-days, Microsoft patched three additional critical RCE flaws affecting Windows components. While exploitation details were not disclosed, the classification indicates a high likelihood of weaponization once exploit tooling becomes available.

Detecting React2Shell: What Security Teams Should Be Watching for Right Now
Since the disclosure of CVE-2025-55182 on December 3, 2025, most of the attention around React2Shell has centered on patching timelines and framework exposure. That is necessary, but for many environments, detection is the real safety net while fixes are staged, tested, and deployed. This vulnerability enables unauthenticated remote code execution against React Server Components through a single crafted HTTP request, and public proof-of-concept code is already circulating. With default configurations proving exploitable in most cases, security teams should assume active scanning and live exploitation attempts are already taking place.
The core behavior to watch for is unexpected server-side command execution originating from Next.js, React Router, or other RSC-backed runtimes. Once the deserialization flaw in the React “Flight” protocol is triggered, attackers can instruct the server to spawn shell commands directly. In practice, this often surfaces as web-facing services suddenly executing file system commands, downloading secondary payloads, or opening outbound connections that do not align with normal application behavior. Any instance of a web server process invoking utilities like ls, cat, curl, wget, chmod, or similar tools in production should be treated as a high-confidence signal.
Runtime detection has already proven effective against this activity. The Sysdig Threat Research Team reinforced its “Suspicious Command Executed by Web Server” logic to catch React2Shell exploitation as it happens. Their Falco rule focuses on process execution events where a shell is launched by next-server, react-router, waku, or vite-related processes and then used to execute common Unix commands. In observed cases, this rule alone has been sufficient to surface exploitation almost immediately. Additional runtime alerts such as reverse shell detections and UNIX socket redirections have also been triggered during real attack simulations, which aligns with attacker behavior focused on persistence and remote control.
Network-layer protections also play a role, though they should be treated strictly as short-term containment. Cloudflare, Google Cloud Armor, Vercel, and Firebase have all deployed platform-level rules aimed at blocking exploitation attempts tied to unsafe deserialization in POST requests. These controls can reduce opportunistic attacks, but they do not change the underlying application behavior. WAF bypass techniques remain a routine part of modern exploit chains, so organizations relying solely on edge filtering remain exposed.
Vulnerability scanning adds another detection layer, though teams should be cautious about tool quality. Many publicly shared scanners misidentify React2Shell or fail to confirm exploitability accurately. Assetnote released one of the more reliable approaches by triggering a specific server error response tied to the vulnerable deserialization logic. Platforms with integrated vulnerability management can already flag affected React packages directly through software inventory, which helps prioritize response across large environments.
From a defensive standpoint, the detection priority is straightforward: watch for anomalous command execution by web services, monitor outbound connections from application servers that do not normally initiate external traffic, and treat any reverse shell indicators as confirmation of compromise. These signals tend to appear quickly after successful exploitation because attackers gain immediate code execution and typically move to payload delivery or persistence within seconds.
Patching remains the only real fix, but detection is what buys response teams time. Updated React Server Components releases at 19.0.1, 19.1.2, and 19.2.1 remove the vulnerable code path, and patched Next.js versions close downstream exposure. Until those updates are fully deployed, continuous runtime monitoring is the line that separates a blocked exploit attempt from a full server takeover.
BRICKSTORM: How PRC Operators Are Turning VMware and Cloud Infrastructure into Long-Term Access Platforms
CISA confirmed last week that a sophisticated backdoor called BRICKSTORM is being actively used by state-sponsored operators from the People’s Republic of China to maintain long-term, covert access inside U.S. networks. The malware targets both VMware vSphere and Windows environments and is designed for persistence, remote command execution, and stealthy command-and-control. According to CISA, BRICKSTORM gives attackers interactive shell access along with full file manipulation capabilities, making it a powerful post-exploitation platform rather than a simple loader or beacon.
BRICKSTORM is written in Golang and supports multiple C2 channels, including HTTPS, WebSockets, nested TLS, and DNS-over-HTTPS. It can also operate as a SOCKS proxy, which allows attackers to tunnel traffic through compromised systems and pivot deeper into internal networks. One of its more dangerous traits is its built-in self-monitoring logic that automatically reinstalls or restarts the implant if it is disrupted. That single feature sharply increases dwell time by allowing the malware to survive partial remediation efforts.
The malware was first documented in 2024 by Google Mandiant during investigations tied to the zero-day exploitation of Ivanti Connect Secure vulnerabilities, including CVE-2023-46805 and CVE-2024-21887. Since then, the activity has matured. CISA now ties the tool to operations conducted by UNC5221 and a separate China-nexus threat cluster that CrowdStrike tracks as Warp Panda. CrowdStrike reports that Warp Panda has been active since at least 2022 and has focused heavily on VMware vCenter environments inside U.S. legal, technology, and manufacturing organizations throughout 2025.
In one confirmed intrusion, attackers gained initial access to a public-facing web server inside a DMZ using a web shell, then moved laterally into an internal vCenter server where BRICKSTORM was implanted after privilege escalation. From there, the operators harvested service account credentials, accessed a domain controller over RDP, and extracted Active Directory data. They continued moving laterally using SMB to additional jump servers and an ADFS server, where cryptographic keys were exfiltrated. From the compromised vCenter system, they were then able to shovel traffic between hypervisors and guest VMs while disguising BRICKSTORM as a legitimate vCenter process.
CISA’s technical breakdown shows that BRICKSTORM relies on custom handlers to spin up web servers on compromised hosts, establish SOCKS proxy tunnels, and execute commands remotely. Some components are purpose-built for virtualized environments and leverage the VSOCK interface for inter-VM communication, data exfiltration, and resilience across ESXi hosts and guest machines. CrowdStrike confirmed that in several intrusions, BRICKSTORM was deployed alongside two previously undocumented Golang implants named Junction and GuestConduit. Junction acts as a local HTTP command server and proxy layer on ESXi hosts, while GuestConduit sits inside guest VMs and maintains a persistent VSOCK listener on port 5555 to bridge traffic back to the hypervisor.
Initial access continues to rely on edge device exploitation and stolen or abused credentials. Confirmed vulnerabilities include multiple Ivanti Connect Secure flaws, VMware vCenter bugs such as CVE-2024-38812, CVE-2023-34048, and CVE-2021-22005, as well as CVE-2023-46747 in F5 BIG-IP. Once inside vCenter, the attackers use SSH, the privileged “vpxuser” account, and SFTP to move laterally and shuttle data between hosts. Their cleanup discipline remains strong, with timestomping, aggressive log clearing, and short-lived rogue virtual machines used for staging operations before being destroyed.
What makes Warp Panda’s activity especially concerning is its cloud focus. CrowdStrike described the group as “cloud-conscious,” noting repeated abuse of Microsoft Azure environments after on-prem compromise. Attackers accessed OneDrive, SharePoint, and Exchange by stealing browser session tokens and replaying them through BRICKSTORM tunnels. In at least one case, they registered new MFA devices to entrench access and used Microsoft Graph API calls to enumerate service principals, applications, directory roles, and user mailboxes. This shows a clean operational bridge between on-prem virtualization compromise and direct exploitation of SaaS identity planes.
The operational goal is not disruption. Everything about this malware stack points to intelligence collection and quiet, long-term access. CrowdStrike observed attackers cloning domain controller virtual machines inside vCenter to extract Active Directory databases offline. They also accessed employee email accounts aligned with Chinese government interest areas and performed limited reconnaissance against foreign government networks from within U.S. infrastructure. This is classic strategic access behavior backed by modern virtualization tradecraft.

A new round of activity tied to China-based operators began almost immediately after details of CVE-2025-55182 were released. The flaw, now nicknamed React2Shell, affects React Server Components and grants remote code execution without authentication. With a perfect CVSS score of 10.0, the weakness attracted interest from multiple actors within hours, according to new reporting from Amazon Web Services.
Patches and Early Exploitation Attempts
Patches landed in React versions 19.0.1, 19.1.2, and 19.2.1. Even with fixes available, attempts to exploit unpatched systems appeared nearly in real time across AWS MadPot honeypots. CJ Moses, CISO of Amazon Integrated Security, noted that the traffic matched long-running Chinese state-linked infrastructure and patterns that analysts have tracked for several years.
Earth Lamia’s Activity
One cluster of attempts came from sources tied to Earth Lamia, the same group responsible for exploiting SAP NetWeaver (CVE-2025-31324) earlier this year. Earth Lamia has shown wide geographic reach, hitting organizations across financial services, logistics, retail, higher education, government entities, and general IT across Latin America, the Middle East, and Southeast Asia. Their behavior around React2Shell fits with that pattern: broad reconnaissance, automated probing, and a desire to reach new entry points before defenders finish patching.
Jackpot Panda’s Parallel Interest
A second wave matched indicators linked to Jackpot Panda. This actor has a long-running focus on gambling-adjacent operations in East and Southeast Asia, and is known for supply chain compromises, including the Comm100 incident in 2022. Research from CrowdStrike and ESET has tied Jackpot Panda to a series of campaigns that rely on manipulated installers, staged implants, and credential theft. More recent work suggests that I-Soon, a Chinese contractor, may have supported portions of those operations due to infrastructure overlap.
By 2023, Jackpot Panda had shifted attention inward, aiming at Chinese-speaking users through trojanized CloudChat installers. Those installers set up a multi-stage chain that delivered an implant named XShade, which analysts say overlaps with the group’s earlier CplRAT tooling. Their presence in the early React2Shell exploitation window signals how quickly established operators adjust playbooks once a fresh entry point appears.
What Early Probing Looked Like
AWS observed attackers testing basic shell commands, creating or modifying files such as /tmp/pwned.txt, and attempting to read /etc/passwd. This pattern reflects the early phase of an opportunistic campaign—simple checks to confirm that the target is vulnerable, followed by a gradual shift into more tailored post-exploitation activity. The same scanners also attempted to weaponize N-day issues such as the NUUO Camera flaw (CVE-2025-1338), which points to a broad sweep rather than a single-purpose operation.
Moses described the workflow as a routine cycle for these groups: watch vulnerability disclosures closely, grab public exploit code as soon as it appears, and feed it into sweeping infrastructure that tests multiple CVEs at once. Whoever falls behind on patching becomes the easiest target.
Cloudflare’s Brief Outage
At the same time, the broader ecosystem felt the ripple effect of the disclosure. Cloudflare experienced a short but very visible service interruption that produced waves of 500 errors across major sites. The company later clarified that the problem came from an internal change to its Web Application Firewall. The update was intended to expand protection for the new React2Shell issue. A parsing error caused the outage, not any attempt by threat actors to hit Cloudflare’s systems.

A joint investigation by BCA LTD, NorthScan, and ANY.RUN has provided an unusually clear look into one of North Korea’s most persistent infiltration methods. Instead of relying on malware or exploit chains, the operators tied to Lazarus Group’s Famous Chollima division attempted to slip remote IT workers into Western companies under stolen or borrowed identities. The research teams managed to watch this activity play out live, using purpose-built sandbox environments that the operators believed were ordinary developer laptops.
How the Scheme Works
The operation began with a familiar introduction: a recruiter message offering a remote IT position. In this case, the recruiter used the alias “Aaron,” also known as “Blaze,” a persona previously linked to Chollima activity. Blaze’s pitch followed the same pattern seen in earlier cases, presenting a job-placement “business” that would place a U.S. developer in a remote role, while a North Korean operator actually performed the work.
The goal remained the same as in past incidents. Operators attempted to borrow or take over an identity, pass interviews with AI-generated answers, work remotely by controlling the victim’s laptop, and route the salary back to DPRK channels. Once Blaze requested everything from SSN and government ID to full-time remote access and uninterrupted laptop availability, the researchers shifted into a controlled environment.
The Fake Laptops That Exposed the Operation
BCA LTD’s Mauro Eldritch deployed ANY.RUN’s long-running virtual machines, configured to appear indistinguishable from real personal workstations. They carried typical developer tools, normal browser history, and realistic usage patterns, along with network routing that matched U.S. residential activity.
These systems gave the research teams full visibility. They could watch sessions in real time, record every action, throttle the network, force crashes, and capture system snapshots. The operators, convinced they were working on legitimate devices, proceeded normally.
What Investigators Saw Inside Famous Chollima’s Toolkit
The sessions revealed a streamlined toolset focused almost entirely on identity takeover and remote access. Once the operators synced their Chrome profiles, they began loading the tools they rely on across many of these campaigns.
The setup included AI-driven platforms such as Simplify Copilot, AiApply, and Final Round AI, which helped automate job applications and provide pre-written interview responses. Browser-based one-time passcode utilities such as OTP.ee and Authenticator.cc appeared as soon as they collected personal documents, giving them the ability to manage the victim’s two-factor authentication.
Google Remote Desktop, configured through PowerShell with a fixed PIN, became the primary access channel. To validate the environment, the operators ran simple reconnaissance utilities such as dxdiag, systeminfo, and whoami. All traffic consistently moved through Astrill VPN, matching patterns tied to earlier Lazarus infrastructure.
At one point, an operator even left a Notepad message requesting uploads of a government ID, SSN, and banking details. The intent behind the scheme was unmistakable: complete control of the identity and workstation of a U.S.-based employee without pushing malware or triggering traditional defenses.
Why This Matters for Employers
The activity highlights a growing risk for hiring teams. Remote recruitment provides attackers with a quiet avenue into corporate environments. Instead of breaching external services or exploiting software vulnerabilities, they gain access by passing job interviews and taking control of an employee’s laptop once hired.
This raises the stakes beyond a single compromised worker. A successful infiltrator could reach internal dashboards, sensitive operational systems, or even managerial accounts if the organization does not have strong identity and endpoint controls. The investigation shows that these schemes rely on social engineering, identity theft, and remote-access tooling rather than traditional malware delivery.
Building internal awareness and giving staff a place to report suspicious interactions can play a significant role in catching these schemes early. Companies that review unusual requests, identity inconsistencies, or access demands are in a stronger position to prevent such infiltration attempts before they escalate into operational consequences.
