The repository, often attributed to a user named "LCFCASD," was titled "ICE_TEA_BIOS" and described as "BIOS Code from project C970". The leaked data was reportedly developed by , a major firmware vendor for computer manufacturers, and contained extensive references to Lenovo systems. The archive includes several critical categories of data: Complete UEFI firmware source code for the Alder

Shortly after the leak was discovered, the original GitHub repository and its major mirrors were taken down due to DMCA notices or terms of service violations. Intel integrated the leaked components into its bug bounty program, encouraging researchers to report any flaws found in the code for rewards rather than exploiting them. The leaked data was reportedly developed by ,

Compilation tools, change logs, and internal scripts used to build and test BIOS images.

Intel confirmed the authenticity of the leak but maintained that it did not immediately expose new vulnerabilities, as their security model does not rely on "security through obscurity". However, security researchers noted several long-term risks:
