The source code for the BlackLotus UEFI bootkit has leaked online, allowing greater insight into a malware that has caused great concern among the enterprise, governments, and the cybersecurity community.
BlackLotus is a Windows-targeting UEFI bootkit that bypasses Secure Boot on fully patched Windows 11 installs, evades security software, persists on an infected system, and executes payloads with the highest level of privileges in the operating system.
Today, security firm Binarly told BleepingComputer that the source code of the BlackLotus UEFI bootkit was leaked on GitHub by the user 'Yukari.
"The leaked source code isn't complete and contains mainly the rootkit part and bootkit code to bypass Secure Boot," stated Binarly's co-founder and CEO Alex Matrosov.
With the bootkit's source code now widely available, it is also possible that competent malware authors might create more potent variants that can bypass existing and future countermeasures.
