Background

CISA (Cybersecurity and Infrastructure Security Agency) and the open-source community have responded to reports of malicious code being embedded in XZ Utils versions 5.6.0 and 5.6.1. This activity has been assigned CVE-2024-3094.

XZ Utils is data compression software commonly present in Linux distributions. The presence of malicious code in these versions may allow unauthorized access to affected systems.

  • Hunt for Malicious Activity: After downgrading, thoroughly search for any signs of malicious activity within your systems.

  • Report Findings: If you detect any malicious activity or suspicious behavior, report your findings to CISA for further investigation.
