"Detecting and Defending Against the XZ Backdoor in Linux Systems"

Malicious code was discovered in the widely used XZ Utils library for Linux systems, enabling remote code execution and bypassing secure shell authentication. The backdoor was introduced by a project maintainer named Jia Tan, who gained credibility over two years and eventually added the malicious code to the XZ Utils release. The sophisticated supply chain attack highlights the potential risks associated with open-source software and the need for organizations to adopt tools and processes to identify tampering and malicious features in their development pipeline.
