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…

AI risk is often discussed like it is one massive category, but most organizations face a narrower and more practical set of problems: sensitive data entering tools that were never approved, AI features being added into business platforms without security review, employees relying on generated answers without validation, developers embedding models into workflows with weak…

A fragile detection rule is a rule that works only under narrow, ideal conditions. It may fire in a lab, catch one known proof-of-concept, or match a specific command from a public report, yet fail as soon as an attacker changes syntax, tooling, parent process, file path, argument order, encoding, log source, or execution method.…

Backups are often described as the last line of defense against ransomware, but that same role makes them a direct target. Modern attackers do not usually encrypt production systems first and hope the victim has weak recovery. They often look for backup servers, backup repositories, cloud snapshots, domain controller backups, hypervisor backups, and SaaS backup…

Token replay is one of the reasons identity compromise has become harder for security teams to contain. In a traditional credential theft scenario, the attacker needs a password, a working MFA path, or some way to trigger a new authentication event. In a token replay scenario, the attacker steals an already-issued authentication or session artifact…

Microsoft’s May 2026 Patch Tuesday includes security updates for 120 vulnerabilities, with no zero-days disclosed this month. Despite the absence of actively exploited or publicly disclosed zero-days, the release is still significant due to the volume of high-severity flaws and the number of critical remote code execution vulnerabilities addressed. This month’s update includes 17 critical…

The recent Canvas security incident tied to ShinyHunters shows how quickly a third-party platform compromise can move from a vendor issue to an operational disruption for schools, universities, faculty, students, and IT teams. Instructure, the company behind Canvas LMS, confirmed that it detected unauthorized activity in Canvas on April 29, 2026. According to Instructure, the…

AI-generated code has moved from developer experiment to production reality, and security teams are now dealing with the result: faster software output, more code entering review, and a new class of AppSec risk where code can look clean, functional, and production-ready, yet still contain common security flaws. GitHub reported that nearly 80% of new developers…

VECT ransomware has emerged as a newer ransomware-as-a-service operation attempting to grow through affiliate recruitment, underground forum promotion, and a structured backend model built around victim management, payload generation, and ransom negotiation. Public reporting from Dark Atlas indicates that the group began advertising its affiliate program in early 2026, later tying itself to BreachForums and…

If you are preparing for CMMC 2.0 certification, the question is not whether you need a SIEM. The question is whether your logging, alerting, and monitoring architecture can survive a Level 2 assessment tied directly to NIST SP 800-171. CMMC 2.0 does not explicitly mandate “deploy a SIEM.” What it does mandate is far more…
