BlackX UEFI bootkit exploits Baton Drop flaw to bypass Secure Boot
Espionage actors weaponised the long-patched Baton Drop Secure Boot bypass into a full UEFI bootkit that disables select endpoint security products — a reminder that unpatched firmware remains a strategic blind spot.
Summary written by editorial AI · Source link below
A new UEFI bootkit named BlackX, deployed in an espionage campaign in early 2026, exploited the old Baton Drop vulnerability to bypass Secure Boot and load a malicious driver designed to interfere with security solutions from Kaspersky and Avast. [...]
Editorial Analysis
Firmware-level persistence bypasses OS-based defences entirely; organisations that neglected Secure Boot revocation list updates face undetectable compromise vectors in espionage campaigns.
Audit firmware patch status and Secure Boot DBX revocation lists across all endpoints; prioritise UEFI integrity monitoring deployment.
A new espionage bootkit highlights that unpatched firmware can render endpoint security investments ineffective.
