Hello everybody.

I am taking the initiative to gather more information regarding the possible precursors and perpetrators of the backdoor.

The purpose of this commentary is focused on open source information (OSINT).

I am not a judge of anyone or any action that may occur, the objective of this comment is to help through accurate and quick information to help the core developers of the affected packages and consequently the Linux kernel (which may have been indirectly or directly affected) take action necessary in relation to the fact that occurred.

NOTE: This comment will always have "edit" so always review it for information.

Information I have so far.

Summary: 1. GitHub Account Suspension: - The accounts of @JiaT75 and @Larhzu were suspended by GitHub. - All Tukaani repositories, including downloads, were disabled. - Investigate the cause of the account suspensions and whether there is any correlation with suspicious activities.

2. Possible Backdoor in xz/liblzma: - There are concerns about the presence of a backdoor in xz/liblzma. - Investigate whether there is evidence of compromise in the source code and recent updates. - Examine potential impacts, especially if the software is used in critical systems.

3. Updates and Patches in Packages: - Note recent updates in packages such as MinGW w64, pacman-static, Alpine, and OpenSUSE. - Review changelogs to understand if these updates are related to security fixes.

4. Jia's Activities on Platforms and Projects: - Investigate Jia's contributions to different projects and platforms, such as Arch Linux, Alpine Linux, and OpenSUSE. - Check for correlations between Jia's activities and reported security issues.

5. Libera Registration Information: - Analyze Jia's registration details on Libera to determine the timeline of their online activities. - Consider correlating this information with other online activities of Jia.

6. VPN Usage: - Confirm Jia's use of VPN and assess its impact on security investigations. - Explore possible reasons for using a VPN and how it may affect the identification and tracking of online activities.
