Bypassing Self-Encrypting Drives (SED) in Enterprise Environments
summary
Claims a widespread design gap: Opal / eDrive SEDs unlock on wake and stay unlocked until power‑cycled or an explicit lock command, so physical access while a machine is asleep or soft‑restarted yields plaintext. Demonstrated exploits include hot-plug/hot-unplug (remove drive, power it externally, swap SATA data), a force-restart via USB emulation (Facedancer/UMAP) to boot an external OS and copy files, and a proposed firmware/SATA sniffer key-capture. Demos use USB↔SATA adapters and caused Windows crashes; mitigation is forced power‑off/hibernate, BIOS lockdown, or vendor fixes (Lenovo eDrive behavior differs).
