What Zero-Day Response Should Be in the Post-Mythos Era
September 15, 2026 · BleepingComputer · Severity: CRITICAL
AI is shrinking the time between vulnerability disclosure and exploitation, leaving defenders less time to wait for patches or public exploits. Picus Security explains how exploitability validation, security control testing, and autonomous pentesting can help teams close exposure gaps before attackers arrive.
Key Takeaways
- Picus Security argues that AI is compressing the window between vulnerability disclosure and exploitation for defenders.
- Zero-day response strategies must shift from waiting for patches to proactive exploitability validation and security control testing.
- Autonomous penetration testing and continuous validation are becoming essential to close exposure gaps before attackers can exploit them.
