The rule 'Yum Package Manager Plugin File Creation' detects file creation and renaming events specifically in the plugin directories associated with the Yum package manager on Linux systems. Given that Yum manages packages predominantly on Fedora-based distributions, an attacker may exploit plugin functionalities to inject malicious code, maintaining persistence on the system. This detection is vital as it helps identify unauthorized modifications potentially indicating a compromise. The rule uses EQL (Event Query Language) to track file actions, incorporating specific criteria to exclude legitimate processes and temporary files to reduce false positives. It highlights the importance of monitoring and securing Yum plugin directories due to their potential vulnerability to malicious exploits.
