MYRA RAT: systemd-userdbd Process Masquerade via prctl from npm/node Parent
This rule detects instances where a process named 'systemd-userdbd' is executed from a file path other than the standard locations ('/lib/systemd/systemd-userdbd' or '/usr/lib/systemd/systemd-userdbd'). Such behavior is often indicative of masquerading, where malicious actors rename their executables to match legitimate system services to evade detection. The rule additionally flags when the parent process is a common interpreter or package manager, which increases the likelihood of malicious activity.
