What it detects

This rule identifies process executions of common Linux commands used to gather system and hardware information, including uname, hostname, uptime, lspci, dmidecode, lscpu, and lsmod. Such discovery activity helps attackers profile the host environment before follow-on exploitation or lateral movement. The detection relies on Linux process creation telemetry by matching the executed image path ending with these utilities.
