BIOS source code for Intel Alder Lake chipsets allegedly leaked online

An unknown individual allegedly deliberately leaked the BIOS source code for Intel Alder Lake using an anonymous 4chan imageboard, and a copy of the material was subsequently posted to GitHub. The files are packed into a ZIP archive of 2.8 GB, when unpacked, the amount of data is 5.86 GB. The authenticity of the materials has not yet been confirmed.

The archive contains many files and tools designed to create BIOS / UEFI firmware for the Intel Alder Lake platform and related chipsets. The source of the data remains unknown, but one document mentions Lenovo.

Even if the authenticity of the data is confirmed, it is not yet clear whether sensitive information can be used to develop exploits, especially if they are not obtained directly from Intel, but from a third-party source. Similar materials are likely to be available from most motherboard manufacturers and OEM partners, and Intel should remove potentially problematic fragments from the dataset before sending sources to third-party vendors. But any classified information therefore has such a status that even small parts of it can become sources of serious vulnerabilities, especially if there is a connection with security components like TPM (Trusted Platform Module).

Last year the attackers twice hacked internal resources of Gigabyte for ransom. In June of this year, the RansomHouse group tried receive a ransom from AMD for refusing to publish 56 GB of stolen confidential data, but the Reds did not pay. Hacking NVIDIA in February turned into a curiosity: the company itself produced cyber attack on intruders.
