What happened
SANS ISC Diary (mid-May 2026) highlights several security items: new malware libraries require updated signatures, increasing detection needs; a simple bypass of Outlook’s Junk-folder link preview can expose users to hidden/malicious links; an analysis of website fraud and techniques for proxying EXE traffic were published; Microsoft’s May 2026 Patch Tuesday addresses 137 vulnerabilities (including 137 Chromium-related Microsoft Edge issues); and Apple released updates fixing 84 vulnerabilities across multiple OSes. Several ISC Stormcast podcast entries were also posted. No specific CVEs were列
