What happened
SANS ISC diary RSS entries (mid-April 2026) covering multiple operational intelligence items: a Lumma Stealer infection observed alongside Sectop RAT (ArechClient2); ongoing internet-wide probes (since 2026-03-10) scanning for AI model endpoints (claude, openclaw, huggingface, etc.) reported by DShield sensors; scans for the EncystPHP webshell (noted targeting vulnerable FreePBX instances); a guest diary on compromised DVRs and how to find them; and analysis of a large Microsoft Patch Tuesday (April 2026). Several daily “ISC Stormcast” podcast entries are also listed.
