What Zero-Day Response Should Be in the Post-Mythos Era

What Zero-Day Response Should Be in the Post-Mythos Era
AI is compressing the time between vulnerability disclosure and real-world exploitation, and the PaperCut incident shows how defenders can be forced to respond before a patch or public exploit even exists. The article argues for combining exploitability validation, security control validation, and agentic pentesting to close exposure gaps in hours, not weeks. #PaperCut #PicusSecurity #CVE-2026-1001 #TheValidationSummit26 #IranianThreatGroup

Keypoints

  • PaperCut was exploited before a stable patch or public exploit was available.
  • Vulnerability response time is shrinking from days to hours.
  • Exploitability should be tested as a chain of techniques, not only with a live payload.
  • Security controls can be validated immediately to close gaps before an exploit appears.
  • Agentic pentesting confirms ground truth once a working exploit is published.
