Yes. Intel ME (CSME) runs its own MINIX-based OS on a dedicated co-processor with direct RAM, network, and hardware access—below Ring 0 and independent of your main OS. With ME-level control (via exploit like CVE-2025-20037 TOCTOU escalation, AMT provisioning, or firmware mod): - BitLocker: Bypassed by reading keys from memory/TPM or AMT out-of-band recovery boot (proven in multiple vulns, e.g. 2018 F-Secure & 2026 AMT disclosures). - Secure Boot: Ignored, as ME controls early boot stages. - Kernel AV: Evaded entirely—ME sees everything pre-OS, can inject/hide undetected. It stays active when "off" but plugged in. Full bypass requires ME access (often local/network config dependent), but once there, OS precautions are irrelevant. Partial neutering via me_cleaner works on some boards but risks bricking.
Post summary
The post details Intel ME’s privileged capabilities that can bypass key OS security features, mentions a mitigation tool, but lacks evidence of a PoC, exploit tool, or active exploitation.
