What it detects

This rule detects the CivilDefense lure executable spawning civildefensestarter.exe, the Pronsis Loader chain used in a Russia-aligned campaign to stage PURESTEALER against Ukrainian military recruits. The parent-child masquerade using civil defense themed filenames indicates second-stage loader execution.
