    Not Just Research: Threat Actors Are Weaponizing AI for Ransomware

    AI-powered ransomware is no longer a distant possibility. Although the recently surfaced PromptLock turned out to be a research prototype created at NYU Tandon School of Engineering, attackers are already using tools like Claude Code to automate reconnaissance, exploitation, and extortion in the wild. What began as an academic demonstration of “Ransomware 3.0” has already been mirrored by real threat actors targeting healthcare, defense, and financial organizations

    When PromptLock samples first appeared on VirusTotal in August 2025, security researchers suspected a new form of ransomware. Analysis by ESET showed it relied on OpenAI’s GPT-OSS:20b model, dynamically generating Lua scripts to perform reconnaissance and execute malicious actions. Soon after, academics confirmed that PromptLock was in fact a controlled proof-of-concept. Their goal was to demonstrate how large language models could coordinate an entire ransomware chain, from surveying a victim’s environment to deploying customized payloads and even writing tailored extortion notes. The research highlighted how easily a benign-looking AI utility could conceal hidden instructions, making detection increasingly difficult.

    The fact that PromptLock was only a lab project does not mean the threat is hypothetical. Anthropic’s August 2025 threat intelligence report revealed real-world misuse of its Claude Code agent. According to the report, attackers were able to use the tool for reconnaissance, lateral movement, and large-scale data theft, embedding their preferred tactics and playbooks into configuration files so the assistant would respond in ways that supported their campaign. The same system generated ransom notes, packaged malware with evasion techniques, and analyzed stolen data to set extortion demands, some of which exceeded half a million dollars. Victims ranged from a defense contractor to financial institutions and healthcare providers, with stolen material including social security numbers, banking details, patient records, and ITAR-controlled documentation.

    Anthropic responded by banning the malicious accounts and working to strengthen its detection capabilities. Security experts stress that although the core techniques of ransomware have not changed, AI drastically lowers the barrier to entry and accelerates every phase of an attack. As Exabeam’s Steve Povolny observed, what once required teams of skilled operators can now be achieved faster and cheaper through modular, AI-driven tasks, in the same way non-coders now build enterprise applications with AI assistance.

    PromptLock itself may be only a proof-of-concept, but its design reflects tactics that are already active in the wild. The lesson for defenders is clear: AI is now serving attackers not just as a consultant, but as an operator, compressing the time it takes to plan and launch ransomware campaigns. Security teams will need to assume that adversaries can rapidly construct large-scale, tailored attacks with the same ease that businesses now adopt AI to streamline development and operations.

    CVE-2025-42957: Critical SAP S/4HANA Code Injection Vulnerability Actively Exploited

    A newly confirmed wave of exploitation is targeting CVE-2025-42957, a critical code injection flaw in SAP’s S/4HANA ERP platform. First disclosed and patched in SAP’s August 2025 security updates, the vulnerability was discovered by SecurityBridge and carries a CVSS v3 score of 9.9. The issue affects both on-premises and private cloud deployments of S/4HANA and is now being abused in the wild, with exploitation attempts spiking after the release of SAP’s patch.

    The vulnerability allows attackers with only low-privileged user access to inject ABAP code into the system, ultimately giving them complete control of both the SAP environment and the host operating system. Although a valid account is required, the complexity of the attack is minimal and can be carried out remotely over the network. According to SecurityBridge, the patch is relatively easy to reverse engineer, which means attackers can quickly develop working exploits.

    Reports from both SecurityBridge and Pathlock confirm that malicious actors are already testing and abusing this flaw. Once exploited, an attacker could directly manipulate or delete corporate data in the SAP database, create persistent backdoor accounts with administrative privileges, steal hashed passwords, and extend control into the host operating system. The fact that a single compromised user account can lead to full system compromise makes this vulnerability especially dangerous.

    SAP customers are strongly urged to apply the August 2025 patches without delay. Beyond patching, SecurityBridge advises enabling the Unified Connectivity framework (UCON) to restrict remote function call (RFC) usage, and monitoring logs carefully for unusual RFC activity or newly created administrative accounts. Organizations should also audit privileged accounts and system activity to ensure attackers have not already established persistence.

    CVE-2025-42957 highlights how attackers continue to focus on SAP environments as high-value targets. The vulnerability requires little effort to exploit, provides complete system access, and has already been weaponized in real-world attacks. Organizations that delay remediation face the risk of data theft, operational disruption, and potentially long-lasting compromise.

  • What is ISO 27001 and How Can It Benefit Your Organization?

    What is ISO 27001 and How Can It Benefit Your Organization?

    Cybersecurity leaders know that technical defenses alone are not enough. To truly safeguard sensitive information, organizations need a structured framework that brings together people, processes, and technology. That’s where ISO/IEC 27001 comes in. As the most widely recognized international standard for information security management, ISO 27001 helps organizations build a resilient Information Security Management System (ISMS) that reduces risk, ensures compliance, and inspires trust across clients and partners.

    For companies operating in highly regulated sectors such as healthcare, finance, and defense, ISO 27001 certification has quickly become a prerequisite for doing business. But even beyond compliance, the standard offers strategic advantages that extend well into daily operations.

    Understanding ISO 27001

    ISO 27001 establishes a clear framework for managing information security by requiring organizations to identify risks, implement controls, and continuously refine their defenses. At its foundation is the CIA triad:

    • Confidentiality – protecting sensitive information from unauthorized access.
    • Integrity – ensuring that data remains accurate and unaltered.
    • Availability – guaranteeing that systems and data are accessible when needed.

    Certification requires more than paperwork; it demands organizational commitment, executive buy-in, and third-party audits to confirm that security is not just documented but operationalized.

    Why ISO 27001 Matters

    Strengthened Security and Reduced Breach Risk

    The structured risk assessments required by ISO 27001 uncover blind spots in existing security programs and ensure that controls evolve alongside new threats. This makes breaches less likely and less damaging when they occur.

    Increased Trust With Clients and Partners

    Certification demonstrates to customers that their data is handled responsibly. In a climate where supply chain security is under constant scrutiny, ISO 27001 signals maturity and accountability.

    Competitive Advantage in the Marketplace

    For many contracts, particularly in government and critical infrastructure, ISO 27001 is not optional. Organizations without certification risk being sidelined, while certified entities gain a competitive edge.

    Cost Savings Through Prevention

    Data breaches are expensive, with costs extending well beyond regulatory fines. By reducing the likelihood and impact of incidents, ISO 27001 helps organizations protect both reputation and bottom line.

    Streamlined Compliance Across Frameworks

    Because ISO 27001 aligns closely with frameworks like NIST CSF, GDPR, and SOC 2, certification can reduce the burden of overlapping audits and improve efficiency for compliance teams.

    Building a Culture of Security

    One of ISO 27001’s most impactful benefits is cultural. By embedding information security into every layer of operations, organizations move beyond check-the-box compliance and foster a security-first mindset. Employees receive ongoing training, human error is reduced, and decision-making increasingly considers risk alongside business goals.

    How Netizen Can Help

    Achieving ISO 27001 certification requires expertise and sustained effort, but you don’t have to go it alone. Netizen has guided government, defense, and commercial organizations through complex compliance initiatives, helping them align security programs with business objectives.

  • ClickFix Attack Uses AI Summaries to Spread Malware

    ClickFix Attack Uses AI Summaries to Spread Malware

    Researchers have detailed a new proof-of-concept attack showing how adversaries can use AI-generated summaries to push ransomware and other malicious commands directly to unsuspecting users.

    How ClickFix Works

    The tactic, called ClickFix, manipulates victims into running self-sabotaging commands under the guise of resolving an error or fixing an issue. In past incidents, attackers impersonated Booking.com or injected fake reCAPTCHA prompts, tricking users into pasting commands into the Windows Run prompt. In one campaign, over 100 automotive dealership websites briefly displayed malicious instructions to visitors.

    The new proof-of-concept from CloudSEK takes ClickFix a step further by abusing AI summarization tools. Researchers showed how attackers could embed malicious instructions into HTML content using techniques like invisible white-on-white text, zero-width characters, tiny font sizes, and off-screen text placement. While these elements remain invisible to a human reader, they dominate an AI model’s context window, surfacing prominently in generated summaries.

    When an AI assistant, browser extension, or email summarizer processes the content, the summary may end up displaying the hidden payload as if it were legitimate advice. CloudSEK demonstrated how such a summary could instruct a victim to paste a PowerShell command into the Run prompt, initiating a ransomware infection. Because the instructions appear to come from the AI summarizer itself, not an external attacker, the victim is far less likely to question them.

    CSS Obfuscation and Prompt Overload

    The success of this attack relies on a blend of CSS obfuscation and what researchers call “prompt overdose.” By repeating hidden payloads multiple times in the HTML, the attacker ensures that the malicious instructions outweigh legitimate context during summarization.

    This manipulation effectively turns the AI tool from a passive summarizer into an active participant in the social engineering chain. What looks like a harmless article, blog post, or email to a human user may, once summarized, output only the attacker’s malicious instructions.

    Defensive Recommendations

    CloudSEK’s guidance for defenders focuses on improving how AI pipelines preprocess and handle content:

    • Summarizers should normalize or strip suspicious CSS attributes before processing inputs.
    • Enterprises should implement prompt sanitizers that filter hidden payloads before they reach summarization models.
    • Detection rules should be created for repeated, hidden text patterns that could dominate AI outputs.
    • Organizations deploying internal AI summarizers should enforce strict preprocessing policies at gateways, content systems, and browser extensions.

    Most importantly, researchers emphasize the need for enterprise-level AI policy enforcement and secure design patterns that prevent AI outputs from triggering sensitive actions without explicit user approval.

  • Netizen: August 2025 Vulnerability Review

    Netizen: August 2025 Vulnerability Review

    Security vulnerabilities are a common occurrence in managing any business’s organizational security. The prompt patching and remediation of any new vulnerabilities are critical to reducing the outside attack surface. Netizen’s Security Operations Center (SOC) has compiled five critical vulnerabilities from August that should be immediately patched or addressed if present in your environment. Detailed writeups below:

    CVE-2025-7775

    CVE-2025-7775 describes a critical memory overflow vulnerability affecting NetScaler ADC and NetScaler Gateway when configured in several modes, including Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy), AAA virtual server, and load balancing virtual servers bound with IPv6 services or DBS IPv6 servers, as well as CR virtual servers of type HDX. The vulnerability arises from improper memory handling that can be triggered remotely, allowing an attacker to achieve remote code execution or denial of service depending on the exploitation path. With network-based access, an attacker could craft malicious packets targeting exposed NetScaler services, leading either to the execution of arbitrary code on the device or the crash and disruption of critical VPN and proxy services.

    This flaw is particularly dangerous in enterprise and cloud environments where NetScaler appliances serve as critical access gateways, since exploitation could result in full compromise of infrastructure, service outages, and lateral movement into internal networks. The vulnerability has been assigned a CVSS v3 base score of 9.8, with a vector of AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, reflecting its low attack complexity, lack of required privileges, and ability to compromise confidentiality, integrity, and availability. Under CVSS v4, the score remains severe at 9.2, further underscoring the risk in production environments. Public reporting confirms that this issue has already been exploited as a zero-day, with CISA adding it to the Known Exploited Vulnerabilities (KEV) catalog and multiple security researchers tracking widespread attacks. Reports indicate that over 28,000 NetScaler appliances remained exposed to the flaw at the time of disclosure, amplifying the urgency for remediation.

    Citrix addressed CVE-2025-7775 in emergency updates released on August 26, 2025, as part of a security bulletin that also included two additional NetScaler vulnerabilities. Organizations running affected versions of NetScaler ADC and Gateway should immediately apply the patches provided by Citrix, or implement compensating controls such as disabling IPv6 bindings and restricting external exposure of management and gateway interfaces until patching is complete. Exploitation of this flaw can grant attackers direct access to internal systems by hijacking critical VPN or load balancing infrastructure, making rapid patching and hardening of NetScaler environments an operational priority. More detailed guidance and official mitigation steps are available from Citrix’s advisory and the CISA KEV catalog.

    CVE-2025-53771

    CVE-2025-53771 describes a medium-severity improper authentication vulnerability in Microsoft Office SharePoint that allows an unauthorized attacker to perform spoofing attacks over a network. The flaw stems from insufficient validation within SharePoint’s authentication mechanisms, which permits a malicious actor to manipulate requests and impersonate legitimate users or services. By exploiting this weakness, an attacker could craft specially designed network requests to trick SharePoint into granting them access under a falsified identity, undermining the trust model of the platform. This can allow further exploitation when chained with other vulnerabilities, particularly in the ToolShell exploit chain where spoofing was used to bypass protections and gain entry into sensitive administrative interfaces.

    The vulnerability poses a significant risk in enterprise environments because SharePoint often serves as a central hub for collaboration, document storage, and workflow automation. Spoofing attacks targeting SharePoint can compromise the confidentiality of business-critical data and may facilitate privilege escalation or lateral movement if an attacker manages to impersonate privileged users. While this issue requires network access, the attack complexity is low and no user interaction is necessary, meaning it can be reliably executed once the attacker identifies a vulnerable system. The vulnerability has been assigned a CVSS v3 base score of 6.5 with a vector of AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, highlighting the impacts to confidentiality and integrity but not availability. Under CVSS v2 scoring, the base score is listed at 7.5 due to differences in weighting methodology.

    Microsoft patched CVE-2025-53771 in July 2025 as part of updates addressing the ToolShell exploit chain, which included several interlinked SharePoint flaws. The vulnerability is actively monitored in security advisories and was quickly added to exploitation watchlists because of its role in enabling bypasses of earlier mitigations. Organizations running affected SharePoint environments should apply Microsoft’s July 2025 security updates without delay and ensure that their SharePoint instances are not directly exposed to the internet. CISA and Microsoft advisories emphasize the importance of restricting external access, applying network segmentation, and enabling strict authentication controls to reduce the impact of any spoofing attempts. Since this flaw fits into broader exploit chains, especially those demonstrated during Pwn2Own and later expanded by attackers in the wild, administrators should consider it a priority to patch and monitor for signs of exploitation.

    CVE-2025-54948

    CVE-2025-54948 is a critical command injection vulnerability affecting the Trend Micro Apex One on-premises management console. The flaw allows a pre-authenticated remote attacker to upload malicious code and execute arbitrary commands on affected systems. Since this vulnerability does not require prior authentication, exploitation is trivial once an attacker can reach the exposed management console, making it particularly dangerous for organizations that have not restricted external access. Exploitation can lead to full compromise of the endpoint security platform, granting adversaries administrative control over large fleets of protected systems.

    Trend Micro confirmed that this vulnerability, alongside CVE-2025-54987, was exploited in the wild as zero-days in August 2025. Reports indicated active targeting of enterprises, with attackers leveraging the flaw to gain persistence, disable defenses, and deploy secondary payloads. Security researchers and CISA flagged the issue as part of the Known Exploited Vulnerabilities (KEV) catalog, further underscoring its active use in attacks. Temporary mitigation tools were released by Trend Micro to limit exposure until full security patches could be applied, but these mitigations should be treated only as stopgaps.

    The vulnerability has been assigned a CVSS v3 base score of 9.8 (vector: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its critical nature across confidentiality, integrity, and availability. Under CVSS v2, the vulnerability carries a base score of 10. The EPSS probability sits at 0.18488, indicating a significant likelihood of widespread exploitation.

    Organizations using Apex One should immediately apply Trend Micro’s latest patches or, at minimum, deploy the mitigation tools provided while restricting console access to trusted networks. Network monitoring for suspicious uploads, reviewing Apex One administrative activity logs, and implementing compensating controls such as firewall rules and intrusion prevention signatures are recommended until systems are fully remediated. Given its exploitation in the wild, unpatched instances remain high-value targets and should be prioritized for immediate remediation.

    CVE-2025-8088

    CVE-2025-8088 is a high-severity path traversal vulnerability in the Windows version of WinRAR that enables attackers to execute arbitrary code by crafting malicious archive files. Discovered by security researchers Anton Cherepanov, Peter Košinár, and Peter Strýček from ESET, the flaw was confirmed to be exploited in the wild before disclosure, which led to its addition to the CISA Known Exploited Vulnerabilities (KEV) catalog.

    The attack vector relies on specially crafted archive files that bypass WinRAR’s intended directory restrictions. When a user extracts such a file, the embedded payload can overwrite critical files or be executed outside the intended extraction path. Because WinRAR is widely used to handle compressed files, especially in enterprise environments where email attachments and downloads are common, this flaw presents a strong opportunity for attackers to distribute malware, gain persistence, or escalate access within targeted networks. Social engineering campaigns could easily weaponize the vulnerability by disguising malicious archives as legitimate content, tricking users into extraction.

    The vulnerability has been rated as critical under CVSS v2 with a score of 10, while CVSS v3 assigned it a high score of 8.8 (vector: AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Under the updated CVSS v4 framework, it carries a score of 8.4, with the primary risk centered on confidentiality, integrity, and availability impacts through unauthorized code execution. EPSS data places its exploitation probability at 0.05624, underscoring that active use has been observed and further exploitation is likely.

    Organizations should prioritize mitigation by ensuring they are running patched versions of WinRAR and restricting the use of outdated builds. Since exploitation requires users to interact with malicious archives, endpoint detection and monitoring of suspicious archive extraction behavior should also be employed. Where possible, implementing application control, disabling automatic script execution, and limiting the use of WinRAR in high-risk environments can reduce exposure. Security advisories also suggest deploying Windows Software Restriction Policies (SRP) or Image File Execution Options (IFEO) to mitigate exploitation attempts until full remediation is in place.

    CVE-2025-21479

    CVE-2025-21479 describes a high-severity memory corruption vulnerability affecting Qualcomm GPU micronodes, where unauthorized command execution during the processing of a specific sequence of GPU instructions can lead to code execution. This flaw allows an attacker to trigger memory corruption by exploiting improperly validated GPU command streams, potentially resulting in arbitrary command execution within the GPU environment. Since GPUs are heavily leveraged for both graphics rendering and compute workloads, exploitation could allow an attacker to interfere with trusted processes, inject malicious operations, or escalate their control over the device.

    The attack vector is local in nature, as exploitation requires the attacker to execute crafted GPU command sequences on a vulnerable system. This can occur through malicious applications distributed via app stores or sideloaded APKs on Android devices. Once executed, the malicious commands can corrupt GPU memory structures, allowing an attacker to achieve code execution in the context of GPU processes, which can then be leveraged for persistence or to escape into higher-privilege components of the operating system. Reports have confirmed that this vulnerability has been actively exploited in the wild, leading to its inclusion in the CISA Known Exploited Vulnerabilities (KEV) catalog, underscoring the likelihood of targeted attacks against Android and other Qualcomm-powered devices.

    The vulnerability carries a CVSS v3 base score of 8.6 (vector: AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H), reflecting its high impact across confidentiality, integrity, and availability once triggered. Under CVSS v2, it is rated 7.2, with exploitation requiring local access but relatively low complexity. EPSS data places the probability of exploitation at 0.12787, reinforcing the fact that attackers are already using it against exposed devices.

    Google addressed the flaw in the August 2025 Android security bulletin, patching affected devices through firmware updates. Qualcomm also issued fixes for impacted Adreno GPU drivers and urged OEMs to push updates to their devices as quickly as possible. Organizations and end-users are strongly encouraged to apply the latest Android security updates immediately, as devices running outdated GPU firmware remain at significant risk. Mitigations such as restricting the installation of untrusted apps and monitoring for abnormal GPU behavior should be applied until patches are fully deployed.

    Phish Tale of the Week

    Often times phishing campaigns, created by malicious actors, target users by utilizing social engineering. For example, in this email, the actors are appearing as Coinbase. They’re sending us a text message, telling us that our Coinbase account was logged into, and we need to call support if it wasn’t us. It seems both urgent and genuine, so why shouldn’t we? Luckily, there’s plenty of reasons that point to this being a scam.

    Here’s how we can tell not to call this number:

    1. The first warning sign for this SMS is the context in which it was sent. When I recieved this SMS, I immediately knew not to click on the link due to the fact that I do not have a Coinbase account. On top of that, it’s very apparent that this message was blasted out to random numbers: the message doesn’t even include my name or attempt to provide any level of familiarity.
    2. The second warning signs in this email is the messaging. This message tries to create a sense of urgency in order to get you to take action by using language such as “If this was not you.” Phishing and smishing scams commonly attempt to create a sense of urgency/confusion in their messages in order to get you to click their link without thinking about it first. Always be sure to thoroughly inspect the style and tone of all texts before following a link or other attachment sent through SMS.
    3. The final warning sign for this email is the wording; in our case the smisher suggests we call a random number, something that Coinbase support would never do. All of these factors point to the above being a smishing text, and a very unsophisticated one at that.


    General Recommendations:

    A smishing attack will typically direct the user to click on a link where they will then be prompted to update personal information, such as a password, credit card, social security, or bank account information. A legitimate company already has this sensitive information and would not ask for it again, especially via your text messages. 

    1. Scrutinize your messages before clicking anything. Have you ordered anything recently? Does this order number match the one I already have? Did the message come from a store you don’t usually order supplies from or a service you don’t use? If so, it’s probably a phishing attempt.
    2. Verify that the sender is actually from the company sending the message.
    3. Did you receive a message from someone you don’t recognize? Are they asking you to sign into a website to give Personally Identifiable Information (PII) such as credit card numbers, social security number, etc. A legitimate company will never ask for PII via instant message or email.
    4. Do not give out personal or company information over the internet.
    5. Do not click on unrecognized links or attachments. If you do proceed, verify that the URL is the correct one for the company/service and it has the proper security in place, such as HTTPS.

    Many smishing messages pose a sense of urgency or even aggressiveness to prompt a form of intimidation. Any SMS requesting immediate action should be vetted thoroughly to determine whether or not it is a scam. Also, beware of messages that seek to tempt users into opening an attachment or visiting a link. For example, “Fix your account now” may draw the question “What is wrong with my account?” and prompt you to click a suspicious link.

    Cybersecurity Brief

    In this month’s Cybersecurity Brief:

    NetScaler ADC and Gateway Security Bulletin: CVE-2025-7775, CVE-2025-7776, CVE-2025-8424

    Citrix has released a security bulletin addressing three high-severity vulnerabilities affecting NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (formerly Citrix Gateway). The flaws are tracked as CVE-2025-7775, CVE-2025-7776, and CVE-2025-8424. One of these, CVE-2025-7775, is confirmed to be under active exploitation in the wild, making immediate patching critical for organizations relying on these products.

    PromptLock: The First AI-Powered Ransomware Emerges Using OpenAI’s gpt-oss:20b

    ESET researchers have identified a new proof-of-concept ransomware family, codenamed PromptLock, that leverages artificial intelligence to generate its malicious payloads in real time. This marks one of the first documented cases of ransomware built directly around a large language model (LLM), raising new concerns about AI’s role in accelerating cybercrime.

    PromptLock is written in Golang and integrates with OpenAI’s recently released gpt-oss:20b model using the Ollama API. Instead of relying on precompiled binaries, the ransomware dynamically generates Lua scripts during execution, guided by hardcoded prompts. These scripts are capable of:

    • Enumerating the local filesystem
    • Inspecting and selecting target files
    • Exfiltrating chosen data
    • Encrypting files across platforms

    Because the Lua payloads are created at runtime, the indicators of compromise (IoCs) may vary between infections. This variability makes detection more difficult and complicates the work of defenders.

    The ransomware uses the SPECK 128-bit encryption algorithm and can operate on Windows, Linux, and macOS environments. Analysis of current samples suggests it could also be adapted for destructive capabilities, though data-wiping functionality does not yet appear to be active.

    ESET assesses that PromptLock is currently a proof-of-concept rather than a fully weaponized strain deployed at scale. Artifacts linked to PromptLock were uploaded to VirusTotal from the United States on August 25, 2025. No active ransomware campaigns have been confirmed to date.

    One key feature is that PromptLock does not require downloading the full LLM model, which could be many gigabytes in size. Instead, attackers can configure the malware to communicate with a remote server running the model via the Ollama API. This approach reduces the footprint on infected systems while maintaining the flexibility of AI-driven payload generation.

    The appearance of PromptLock illustrates how AI can lower the barrier to entry for cybercriminals. By outsourcing payload generation to an LLM, attackers can:

    • Create variable, unpredictable payloads that evade signature-based defenses
    • Automate the customization of ransom notes and infection routines
    • Scale ransomware development even with limited technical expertise

    This trend is part of a broader shift. Earlier this month, Anthropic confirmed that it banned two groups using its Claude model to develop ransomware variants with advanced encryption and anti-recovery mechanisms. Separately, researchers have warned of novel prompt injection techniques such as PROMISQROUTE, which abuses model-routing systems to downgrade protections and bypass AI safety filters.

    Defenders should treat PromptLock as an early warning of where ransomware development may be heading. AI-powered malware offers attackers agility and adaptability that traditional static analysis will struggle to keep up with.

  • Why Small Businesses Are Prime Targets for Ransomware —And How to Avoid Becoming One

    Why Small Businesses Are Prime Targets for Ransomware —And How to Avoid Becoming One

    Ransomware attacks no longer just affect large corporations and government agencies. In fact, small and mid-sized businesses (SMBs) have become one of the most frequently targeted groups by ransomware operators. Their limited IT budgets, inconsistent patching practices, and reliance on third-party services create a perfect environment for threat actors to exploit.

    Why Ransomware Groups Target Small Businesses

    Threat actors are not only after billion-dollar payouts, they are also opportunistic. Small businesses often lack dedicated cybersecurity personnel and rely on outdated or misconfigured systems, making initial access much easier. Once inside, attackers can rapidly encrypt files or exfiltrate sensitive data for double-extortion tactics.

    1. Lower Barriers to Entry

    Many SMBs rely on legacy systems, shared credentials, weak remote desktop configurations, or improperly secured VPNs. These provide a wide attack surface with minimal resistance. Tools like Cobalt Strike, PowerShell Empire, or even off-the-shelf ransomware kits allow attackers to exploit these weaknesses with little technical sophistication.

    2. Slower Detection and Response

    Without a 24/7 security operations center (SOC) or centralized alerting, malicious activity often goes unnoticed for hours or days. This delay gives attackers ample time to disable backups, escalate privileges, and deploy ransomware payloads across endpoints and file servers.

    3. High Ransom Payment Rate

    Many small businesses cannot afford prolonged downtime. This urgency makes them more likely to pay the ransom to resume operations, especially if their data backups are incomplete, encrypted, or unavailable.

    4. Access to Supply Chain Targets

    By compromising an SMB that serves larger clients, attackers can use that access as a pivot point into more lucrative targets. Managed service providers (MSPs), legal firms, and regional logistics companies are frequently used as stepping stones in broader campaigns.

    Common Ransomware Entry Points in SMB Environments

    Understanding how ransomware is typically introduced into SMB networks is the first step toward defending against it:

    • Phishing emails containing malicious attachments or links to credential-harvesting sites
    • Exposed RDP or SSH services with weak credentials or no MFA
    • Compromised third-party software, including remote monitoring and management (RMM) tools
    • Drive-by downloads from hijacked websites or malvertising campaigns
    • Unpatched systems, especially for known vulnerabilities like ProxyShell (Exchange), PrintNightmare, or Fortinet SSL VPN flaws

    Defensive Strategies That Work

    To defend against ransomware, SMBs need a layered approach that combines prevention, detection, and response. The goal is not only to block initial access but also to reduce lateral movement and limit damage if a breach occurs.

    Implement Endpoint Detection and Response (EDR)

    Traditional antivirus tools often fail to catch modern ransomware strains or fileless attacks. EDR solutions provide behavioral analytics, process monitoring, and memory scanning to detect suspicious activity like credential dumping or PowerShell abuse. They also allow incident responders to isolate infected machines and roll back malicious changes.

    Enforce Strong Access Controls

    Limit administrative privileges to only what’s necessary. Enforce multi-factor authentication (MFA) on all remote access portals and cloud applications. Regularly audit accounts and disable stale credentials, especially service accounts with elevated rights.

    Patch High-Value Targets First

    SMBs may not have the resources to patch every system immediately, but they can prioritize. Focus first on systems exposed to the internet, VPN gateways, and assets holding sensitive data. Track patch status through a vulnerability management platform or vulnerability scanning solution.

    Harden Backup Infrastructure

    A reliable and isolated backup can mean the difference between full recovery and financial collapse. Backups should be encrypted, stored offsite or offline, and regularly tested. Disable backup access from user accounts and ensure backups are not on the same domain as production systems.

    Security Awareness Training

    Human error remains a primary cause of ransomware incidents. Train employees to recognize phishing attempts, avoid macro-enabled attachments, and report suspicious activity. Simulated phishing campaigns are an effective way to test resilience and adjust training accordingly.

    Netizen: Monday Security Brief (8/25/2024)

    Today’s Topics:

    • SDocker Fixes CVE-2025-9074: Critical Container Escape Vulnerability in Docker Desktop
    • New Attack Technique Uses RAR Filenames to Deploy VShell Backdoor on Linux
    • How can Netizen help?

    SDocker Fixes CVE-2025-9074: Critical Container Escape Vulnerability in Docker Desktop

    Docker has released an urgent patch addressing CVE-2025-9074, a critical container escape vulnerability impacting Docker Desktop for Windows and macOS. Rated CVSS 9.3, this flaw could allow a malicious container to break out of isolation, compromise host systems, and access sensitive files.

    The issue is fixed in Docker Desktop version 4.44.3, and security teams are strongly advised to update immediately.

    The flaw stems from how Docker Desktop handled access to the Docker Engine API. Researcher Felix Boulet discovered that containers could communicate with the API at 192.168.65[.]7:2375 without authentication.

    This design oversight meant that a malicious or compromised container could:

    • Launch new containers without needing the Docker socket.
    • Bind the host’s C:\ drive (on Windows) to the container, granting read/write access.
    • Escalate privileges by modifying critical system files or DLLs.

    A proof-of-concept (PoC) exploit showed that a simple web request from a container could mount the host filesystem and compromise the system.

    Researcher Philippe Dugre (zer0x64) demonstrated that attackers could escalate privileges to full administrator access. By mounting the host filesystem, an attacker could:

    • Read sensitive files, including credentials.
    • Overwrite system DLLs to persist as an admin.
    • Deploy backdoors for long-term host compromise.

    Linux systems are not impacted by CVE-2025-9074. Docker on Linux communicates with the Engine API through a named pipe rather than a TCP socket, preventing the same attack vector.

    The primary risk comes from malicious containers controlled by threat actors. However, researchers warn that an SSRF (Server-Side Request Forgery) vulnerability in a separate application could also proxy requests to the Docker API, making exploitation possible without direct container access.

    Depending on request methods available (POST, PATCH, DELETE), attackers could remotely spin up privileged containers and escape to the host.

    Mitigation and Recommendations

    • Update immediately to Docker Desktop 4.44.3 or later.
    • Avoid running untrusted containers, particularly from public sources.
    • Restrict Docker Engine API access and monitor for suspicious container launches.
    • Audit host systems for unauthorized file changes or DLL modifications (Windows).

    Organizations that rely on containers in production should treat this as a high-priority incident and integrate Docker security monitoring into their broader DevSecOps practices.

    New Attack Technique Uses RAR Filenames to Deploy VShell Backdoor on Linux

    Cybersecurity researchers have identified a new Linux malware campaign that abuses malicious RAR archive filenames to deliver the VShell backdoor. The technique allows attackers to bypass traditional antivirus detection by hiding payloads in the filename itself rather than in the file contents.

    The attack begins with phishing emails disguised as invitations to a beauty product survey offering a monetary reward. These messages include a RAR archive attachment named yy.rar. Inside the archive is a file with a specially crafted filename containing embedded Bash commands.

    Example filename:

    ziliao2.pdf`{echo,<Base64-encoded command>}|{base64,-d}|bash`

    When a shell script or command interprets the filename, the embedded payload executes. This leads to the download of an ELF binary tailored to the victim’s architecture, which then connects to a command-and-control server to retrieve and execute the encrypted VShell backdoor.

    Traditional antivirus tools scan file contents, not file names. Since the malicious logic resides in the filename, the payload slips past conventional detection methods. Execution only occurs when the filename is parsed by the shell, not when the archive is extracted, adding another layer of stealth.

    VShell is a Go-based remote access tool used by multiple threat groups, including UNC5174. It provides remote shell access, file operations, process management, port forwarding, and encrypted communication. Because it runs entirely in memory, VShell avoids leaving disk artifacts that could be detected during forensic analysis.

    In addition to VShell delivery, researchers at Picus Security detailed a Linux malware tool called RingReaper. This tool leverages the Linux kernel’s io_uring framework to evade detection by endpoint monitoring tools. By replacing traditional system calls with io_uring primitives, RingReaper avoids hooks commonly used by EDR solutions.

    RingReaper is capable of enumerating system processes, network sessions, and logged-in users, while also enabling privilege escalation through SUID binaries. It can erase traces of its activity after execution, making detection even more difficult.

    Organizations should harden their defenses by sanitizing shell input in scripts, deploying behavioral-based detection systems, and analyzing archive attachments beyond just file content. Linux EDR tools need to adapt to io_uring-based activity, while user awareness training should reinforce caution around unexpected email attachments.

  • Why Security Culture is Critical to Reducing Cyber Risk

    Why Security Culture is Critical to Reducing Cyber Risk

    After two decades of maturing technical defenses, organizations are confronting a difficult reality: even the strongest tools cannot fully protect them if human behavior is left unaddressed. As technology has advanced, attackers have adapted, shifting focus from purely exploiting infrastructure to targeting people directly. In many breaches, the entry point is not a software flaw but a human one.

    For five years in a row, Verizon’s Data Breach Investigations Report has found that the majority of breaches involve a human element. In 2024, nearly 60% of global breaches were traced back to actions or decisions made by individuals. Yet employees are not the problem. Most failures stem from environments where security is unnecessarily complex, communicated in technical jargon, or treated as a barrier to productivity.

    What Defines Security Culture

    Every organization has a security culture, whether intentional or not. The question is whether it supports secure behavior.

    Security culture refers to the shared beliefs, perceptions, and attitudes about cybersecurity across a workforce. When employees believe security is important, understand their role in it, and see themselves as targets, they are more likely to act securely. When they see it as someone else’s responsibility, or as an obstacle, risk rises quickly.

    Behavior follows environment. If policies, tools, and leadership make security difficult, employees will find workarounds. If those same systems simplify security, people are more likely to make safe choices as part of their daily routines.

    Four Levers That Shape Security Culture

    • Leadership signals – Executives set the tone. If they visibly prioritize security with funding, accountability, and organizational support for the CISO, the message is clear.
    • Security team engagement – The way employees experience security day to day matters. Supportive and approachable teams build trust. Teams that are rigid or unhelpful erode it.
    • Policy design – Policies that are overly technical or inconvenient push employees toward insecure shortcuts. Simple, practical rules reinforce the idea that security is achievable.
    • Security training – Training should be engaging, role-specific, and relevant. When it feels outdated or disconnected, it signals that security is just a checkbox.

    Aligning Culture Across the Organization

    Leadership may set direction, but employees measure culture by what they experience daily. If executives talk about security as a priority but policies are impractical, teams are unapproachable, or training is irrelevant, trust breaks down.

    Aligning leadership, policies, team engagement, and training creates the conditions where security becomes part of normal operations. When employees see that security is supported, achievable, and integrated into their roles, the human risks that attackers exploit are significantly reduced.

  • Scattered Spider Hacker “King Bob” Gets 10 Years in Prison

    Scattered Spider Hacker “King Bob” Gets 10 Years in Prison

    A 20-year-old Florida man tied to one of the most disruptive cybercrime groups in recent memory has been sentenced to ten years in federal prison and ordered to pay $13 million in restitution to victims.

    Noah Michael Urban of Palm Coast, Florida, better known in underground circles as Sosa, King Bob, Elijah, Gustavo Fring, and Anthony Ramirez, pleaded guilty earlier this year to charges of wire fraud and conspiracy.

    Federal prosecutors said Urban and his co-conspirators engaged in SIM-swapping campaigns that diverted victims’ mobile phone calls and text messages to devices under their control, allowing the theft of at least $800,000 from five individuals between August 2022 and March 2023.

    Although prosecutors initially recommended an eight-year term, the judge imposed a 120-month sentence along with three years of supervised release. The restitution order, which covers both Florida and California cases against Urban, was set at $13 million.

    Scattered Spider Operations

    Urban was indicted in Los Angeles in late 2024 as one of five key members of Scattered Spider, also tracked as Oktapus, Scatter Swine, and UNC3944. The group specialized in SMS phishing (smishing) and voice phishing (vishing) campaigns that targeted employees of U.S. companies. Victims were lured to fraudulent authentication portals mimicking Okta login pages, tricked into entering passwords and MFA codes, and then exploited for access into corporate environments.

    The operation spanned the summer of 2022 and hit more than 130 organizations, including Twilio, LastPass, DoorDash, MailChimp, and Plex. Stolen access enabled follow-on intrusions, theft of proprietary data, and millions of dollars’ worth of stolen cryptocurrency.

    Star Fraud and SIM-Swapping Tactics

    Urban wasn’t just part of Scattered Spider, he also belonged to Star Fraud, a notorious collective of SIM-swappers with a reputation for attacking major telecom providers. Investigations found that Star Fraud members repeatedly compromised mobile carrier employees, gaining temporary control over victims’ phone numbers.

    In one seven-month span in 2022, Star Fraud boasted of 100 separate intrusions into T-Mobile systems, according to logs published by KrebsOnSecurity. These SIM-swapping capabilities were critical to high-profile extortion campaigns, including the MGM Resorts and Caesars Entertainment breaches in 2023.

    Urban’s Online Persona: “The Com” and Leaked Music

    For years, Urban was a fixture in The Com, a largely Telegram- and Discord-based community of English-speaking cybercriminals. Using the moniker King Bob, he frequently bragged about stealing unreleased rap music, or “grails,” often obtained via SIM-swapping techniques. Some of these tracks were sold; others were given away freely on forums.

    Judge Targeted in Hack

    In an extraordinary development, Urban’s case intersected with a direct attack on the judiciary itself. While Urban was in federal custody, a co-defendant in the California prosecution reportedly hacked into a magistrate judge’s email account and accessed sealed documents tied to Urban’s indictment.

    Court transcripts from February 2025 confirm the breach occurred after an attacker impersonated a judge in a call to a court contractor, successfully requesting a password reset. Judge Harvey E. Schlesinger, presiding over Urban’s case, later described it as a “big faux pas” and confirmed the compromise had been traced to Scattered Spider associates attempting to gather intelligence on Urban’s legal proceedings.

    Urban, speaking through one of his online accounts, has insisted his sentence is unjust, claiming the judge in his case failed to account for his age and bias stemming from the incident.

    Broader Implications

    The sentencing of Noah Urban marks a significant milestone in U.S. law enforcement’s pursuit of Scattered Spider and affiliated groups. Yet the threat posed by these actors remains. Scattered Spider continues to operate, reportedly forming new alliances with ShinyHunters and LAPSUS$ under the larger umbrella of The Com. Analysts say these alliances are intended to consolidate resources in response to law enforcement crackdowns, producing more versatile and dangerous operations.

    Flashpoint research has noted Scattered Spider’s wave-based attack strategy, in which entire sectors are targeted in short, concentrated bursts. By focusing on human weaknesses rather than purely technical flaws, groups like Scattered Spider demonstrate how deception remains one of the most effective paths into corporate systems.

  • The Value of a vCISO: Fractional Security Leadership, Full-Time Peace of Mind

    The Value of a vCISO: Fractional Security Leadership, Full-Time Peace of Mind

    Technology now underpins nearly every function of business, from financial systems to customer engagement platforms. This reliance brings with it an unavoidable reality: cybersecurity is no longer optional. A single breach can cause financial loss, reputational damage, and regulatory penalties. For organizations without the resources or need for a full-time Chief Information Security Officer (CISO), the solution increasingly comes in the form of a Virtual Chief Information Security Officer (vCISO).

    A vCISO provides executive-level cybersecurity guidance remotely, often on a part-time or contract basis. Despite not being embedded within the company, their expertise is directly aligned with strengthening security programs, ensuring compliance, and helping organizations manage cyber risk without the cost of a permanent hire.

    What a vCISO Brings to the Table

    A vCISO offers the same caliber of strategic direction as a traditional CISO but with flexibility that makes the role accessible to organizations of all sizes. Their responsibilities typically include:

    • Developing Security Strategies: Crafting a security roadmap that identifies and mitigates risks.
    • Managing Policies and Procedures: Creating, reviewing, and updating frameworks to align with industry standards.
    • Risk Management and Compliance: Conducting assessments, audits, and ensuring adherence to regulations like HIPAA, PCI DSS, or GDPR.
    • Incident Response: Coordinating swift actions during security incidents to contain and mitigate damage.
    • Training and Awareness: Building a security-first culture by educating employees on threats and best practices.
    • Vendor Risk Oversight: Evaluating the security posture of third-party partners and service providers.
    • Budget and Metrics Management: Ensuring investments in security tools are effective and measurable.

    Through these efforts, a vCISO acts as both strategist and safeguard, guiding leadership teams in balancing operational growth with strong defenses.

    Why the Role Has Grown in Importance

    The escalating frequency and sophistication of cyber threats have accelerated demand for vCISO services. Small and mid-sized businesses, often prime targets for attackers, find value in contracting expertise that would otherwise be out of reach. Large enterprises, too, increasingly turn to vCISOs to supplement in-house leadership or address specialized projects.

    The flexibility of the role became especially evident during the Covid-19 pandemic, when businesses shifted to remote operations. vCISOs adapted seamlessly, continuing to provide oversight without disruption—proving the resilience of fractional security leadership.

    The Cost Advantage

    Hiring a full-time CISO can represent a six-figure expense, not including benefits and overhead. By contrast, a vCISO delivers comparable expertise at a fraction of the cost. The model is inherently scalable, allowing organizations to increase or decrease engagement as needs evolve. This makes vCISO services especially practical for companies in transitional phases, whether scaling rapidly, pursuing compliance certifications, or recovering from incidents.

    For many, the biggest financial advantage lies not only in reduced staffing costs but also in preventing the far greater expense of a major breach.

    Selecting the Right vCISO

    Choosing a vCISO requires more than technical vetting. Organizations should begin by identifying specific needs—whether it’s regulatory compliance, risk management, or strengthening incident response. From there, leaders can evaluate candidates on experience within their sector, qualifications, references, and cultural fit. Clear expectations around deliverables and reporting are key to ensuring success.
