What happened

SANS ISC diary roundup (May 4–11, 2026) covering multiple operational and security topics: implementation of Cloudflare Turnstile CAPTCHAs to mitigate bot traffic; YARA-X 1.16.0 release (minor improvements/bug fixes); disclosure of a new universal Linux local privilege escalation dubbed “Dirty Frag” (related to the recently disclosed Copy Fail issue) with mitigation guidance recommended; reports of cleartext-stored passwords in Microsoft Edge; and an SSL.com root certificate rotation. Actionable items: prioritize Linux kernel updates/mitigations for Dirty Frag/Copy Fail, validate Edge password
