Description
The following analytic detects the execution of Ruby commands with elevated privileges on a Linux system. It identifies processes where Ruby is used with the `-e` flag to execute commands via `sudo`, leveraging Endpoint Detection and Response (EDR) telemetry. This activity is significant because it indicates a potential privilege escalation attempt, allowing a user to execute commands as root. If confirmed malicious, this could lead to full system compromise, enabling an attacker to gain root access, execute arbitrary commands, and maintain persistent control over the affected system.
Detection logic
Detection requirements
- Platform
- LinuxmacOS
The rule states no platform. This is derived from the ATT&CK technique it maps to.
- Log source category
- sysmon_for_linux_eventid_1
Known benign triggers
- False positives are present based on automated tooling or system administrative usage. Filter as needed.
MITRE ATT&CK mappings
0 exclusive techniques.This is coverage no other published rule has; it is not this rule's total technique count.
