Detect bootkits such as BlackLotus and Bootkitty and Secure Boot bypass via DBX and binary checks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Detecting Secure Boot Bypass
> **Legal Notice:** Firmware and Secure Boot assessment must only be performed on systems you own or are explicitly authorized to test. CHIPSEC's write/modify modes and EFI variable manipulation can brick hardware. Run destructive checks only in a lab. This skill is for defensive verification and authorized assessment.
## Overview
UEFI Secure Boot is the firmware-enforced trust chain that only permits boot components signed by keys in the platform's allow-list (db) and not present in the revocation list (dbx). Bootkits defeat this layer to gain pre-OS, persistent, kernel-level control that survives OS reinstalls and disk wipes. **BlackLotus** (2023) was the first publicly observed UEFI bootkit to bypass Secure Boot on fully patched Windows 11, abusing **CVE-2022-21894** ("baton drop") in a vulnerable, signed Windows boot manager to neutralize Secure Boot and disable BitLocker, HVCI, and Defender. **Bootkitty** (2024) was the first PoC UEFI bootkit targeting Linux. Microsoft's **CVE-2023-24932** addressed a related Secure Boot bypass that required a phased dbx (revocation) rollout because revoking the vulnerable boot managers can render systems…

How to install
mdr add adriannoes/awesome-agentic-ai/detecting-secure-boot-bypass@sha256:0115f82d1b735acaThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
