Secure code review has always required more than finding obvious injection bugs or checking whether a developer used the right library call. Good review connects code behavior to trust boundaries, data flow, authorization logic, state changes, error handling, deployment context, and abuse cases. AI does not remove that requirement. It changes the volume, speed, source,…

Service accounts sit at the intersection of identity, application runtime, infrastructure automation, and privileged access. They run Windows services, connect middleware to databases, let pipelines deploy code, let SaaS applications read tenant data, and allow workloads in cloud and Kubernetes environments to call APIs without a person at the keyboard. That operational value also makes…

For many organizations, SOC 2 begins as a customer request. A prospect asks for the report, a contract requires it, or a sales cycle stalls until the organization can prove that it has controls in place to protect customer data. That pressure often turns SOC 2 into a project with a deadline, an audit window,…

Today’s Topics: Self-Replicating AI Worm Shows Malware Can Reason Its Way Through a Network University of Toronto researchers have demonstrated a proof-of-concept AI worm that changes one of the oldest assumptions in worm defense: that the malware arrives with a fixed exploit path. In a preprint posted to arXiv on June 2, a team from…

Living-off-the-land attacks have become one of the clearest examples of a security problem that cannot be solved by malware detection alone. Instead of bringing obvious malicious tooling into an environment, attackers use what is already present: signed Windows binaries, administrative consoles, scripting engines, remote management services, cloud command-line tools, backup utilities, identity platforms, and trusted…

Microsoft’s June 2026 Patch Tuesday includes security updates for 200 vulnerabilities, making it one of the largest patch releases in recent years. The update addresses three publicly disclosed zero-days and 33 critical vulnerabilities, the majority of which are remote code execution flaws. While none of the zero-days are known to have been exploited in the…

Today’s Topics: LLM Agent Used in Post-Exploitation Attack After Marimo Vulnerability Exploit A threat actor was observed using a large language model agent to conduct post-exploitation activity after compromising a publicly exposed Marimo notebook through CVE-2026-39987, a critical pre-authenticated remote code execution vulnerability affecting Marimo versions up to and including 0.20.4. The activity, reported by…

Vulnerability management has always been a race between disclosure, exploitation, prioritization, testing, and remediation. AI is compressing that race. The issue is not simply that attackers have better tools. It is that the entire vulnerability lifecycle is moving faster than the operational processes most organizations use to manage risk. For years, vulnerability management programs were…

Kali365 is the latest reminder that Microsoft 365 phishing has moved beyond fake login pages and stolen passwords. According to the FBI, Kali365 is a phishing-as-a-service platform first seen in April 2026 and distributed mainly through Telegram. Its purpose is direct: help attackers obtain Microsoft 365 OAuth access and refresh tokens, bypass common MFA controls,…

Microsoft is facing criticism from the cybersecurity community after a public dispute with an anonymous researcher escalated into a series of Windows zero-day releases, emergency mitigation guidance, and a broader argument over how major vendors handle vulnerability disclosure. The researcher, known publicly as Chaotic Eclipse or Nightmare-Eclipse, has published multiple proof-of-concept exploits for Windows flaws…
