What happened

SANS ISC diary (13 Jul 2026 feed) aggregates several security items: active scanning targeting MCP servers and AI-assistant credential endpoints (possible credential-harvesting reconnaissance); Wireshark 4.6.7 released addressing 12 vulnerabilities and 16 bugs (patch recommended); a phishing-evasion technique using “comment stuffing” in HTML attachments to try to evade AI-based detectors; an educational “stack simulator” write-up covering stack/memory concepts and exploitation risks; and an explanation of unusual DNS records (NIMLOC/NAPTR/RCS). Also includes routine ISC Stormcast podcast posts
