Project Glasswing is the defensive security story of the month. Anthropic's Mythos Preview found a 27-year-old OpenBSD TCP bug and a 16-year-old FFmpeg flaw. UK AISI's independent eval: 73% success on expert-level CTFs (0% before April 2025), first AI to solve a full 32-step corporate network attack range. Foreign Policy argues Mythos eliminates the exploit window entirely. Barracuda published a post-Mythos action checklist: deploy phishing-resistant MFA, increase scan frequency, automate patching. Patch cycles designed for human-speed exploit development are inadequate now.
