An unknown individual has leaked the source code for Intel’s Alder Lake BIOS onto 4chan, and a duplicate copy was posted to GitHub (now removed). Intel has now confirmed the leak is legitimate and security researchers are checking it out. Magnet link and info is mirrored into my data leaks page.

The file appears to contain a plethora of files and tools geared for building a BIOS/UEFI for Intel’s Alder Lake platform and chipsets. It is unclear where the leaker obtained the files, but one of the documents does refer to “Lenovo Feature Tag Test Information.”

Our proprietary UEFI code appears to have been leaked by a third party. We do not believe this exposes any new security vulnerabilities as we do not rely on obfuscation of information as a security measure. This code is covered under our bug bounty program within the Project Circuit Breaker campaign, and we encourage any researchers who may identify potential vulnerabilities to bring them our attention through this program. We are reaching out to both customers and the security research community to keep them informed of this situation. Intel
