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,…

For most organizations, APIs are no longer a secondary concern sitting behind the application. They are the application’s…

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…

AI-powered phishing is forcing security teams to rethink one of the oldest assumptions in email defense: that malicious messages usually look different from legitimate ones. For years, defenders trained users and tuned controls around obvious signs of fraud, including awkward grammar, misspelled domains, generic greetings, suspicious attachments, and low-quality branding. That model still catches plenty…
