What Defined Defense in 2025

This Binary Defense recap highlights four 2025 trends: EDR‑Freeze attacks that degrade endpoint telemetry without crashing agents, rapid exploitation of CVE‑2025‑53770 integrated into ransomware routines, 'DefendNot' techniques that manipulate Windows security provider registration to silence Defender without alerts, and increasing abuse of RMM tools for access and persistence — all illustrating attackers targeting defender assumptions and control-plane trust and creating visibility gaps that demand sensor-health monitoring and behavior-focused detection.
