We just dodged a bullet...... More like a howitzer round........
This backdoor almost infected Linux everywhere: The XZ Utils close call
The backdoor was discovered because Linux is open source, if it was a closed system it would have infected millions.
It all started when Andres Freund, a Microsoft principal software engineer, became curious about why the SSH remote security code in the Debian Linux beta was running slowly. Freund did some digging and discovered the problem: A chief programmer and maintainer of the xz data compression library, Jia Tan, had put a backdoor in the code. Its purpose? To enable attackers to take over Linux systems.
