Microsoft Defender Bug Triggers False BIOS Update Alerts

⚠️ Microsoft is addressing a logic bug in Microsoft Defender for Endpoint that causes some Dell devices' BIOS firmware to be incorrectly marked as outdated, prompting unnecessary update alerts to users. The company says a fix has been developed and is being prepared for deployment, but it has not disclosed the regions or number of customers affected. Microsoft also recently resolved macOS black screen crashes linked to a deadlock in the Apple enterprise security framework and has been correcting several anti-spam and machine-learning false positives impacting Teams and Exchange Online.

ReVault: Deep Analysis of Dell ControlVault3 Firmware

🔒 This deep-dive by Philippe Laulheret (Talos) dissects Dell's ControlVault3 ecosystem, exposing firmware decryption, memory-corruption flaws, and exploit chains that cross the device/host boundary. The researchers recovered hardcoded keys, reverse-engineered the SCD/SMAU update mechanism, and achieved arbitrary code execution in firmware, enabling persistence and a demonstrated Windows Hello bypass. Practical attacks include forging SCD blobs, backdooring firmware to escalate to SYSTEM, and physically extracting the USH board over USB for rapid compromise.

ReVault: Vulnerabilities in Dell ControlVault3 Firmware

🔒 Talos disclosed five vulnerabilities in Dell ControlVault3 firmware and its Windows APIs, collectively named ReVault. The flaws affect more than 100 Latitude and Precision models and can enable persistent firmware implants that survive OS reinstalls. Attackers with local or physical access may bypass biometric authentication or escalate to Admin/System level. Apply Dell firmware updates and recommended mitigations without delay.
