What it detects

This rule detects execution of dmidecode requesting baseboard information, a host-fingerprinting step used by the Prometei botnet alongside reads of /proc/cpuinfo. Malware profiles infected systems this way before cryptomining. While inventory tools may use dmidecode, its use by unexpected parents warrants review.
