- T1490Inhibit System Recovery

What it detects

This rule detects bcdedit being used to delete recovery settings or force safe boot, an inhibit-system-recovery behavior observed in BlackSuit ransomware intrusions. Operators run this before encryption to prevent victims from booting into recovery and to weaken protections, making it a high-value pre-encryption signal.
