status: test
description: This rule identifies process creation events where a command line invokes CoercedPotato.exe with an "--exploitId" argument. CoercedPotato is used for privilege escalation, so attacker execution of it is a strong indicator of attempted elevation. The detection relies on Windows process creation telemetry including the executable image path, command-line arguments, and matching IMPHASH values.
