You Don't Have to Run an Exploit to Know If You're Vulnerable

**Picus analysis of accelerating CVE weaponization and mitigation via TTP-chaining:** The article warns that CVEs are being weaponized far faster (median time-to-exploit under a day in 2026) and that defenders should move budget from patch velocity to validation (Breach and Attack Simulation/TTP-chaining). It provides a worked example, "Nightmare-Eclipse," describing three Windows zero-days (BlueHammer, RedSun, UnDefend) which together enable SYSTEM-level execution, SAM/SYSTEM hive access via VSS, and disruption of Defender, illustrating how testing attack steps (not firing full exploits) can show real exploitability safely.
