What it detects

This rule detects creation of the local accounts support or whiteninja using net user add, the backdoor accounts provisioned by the ToyMaker access broker after gaining a foothold. Attacker-created local accounts give the operator a persistent, credentialed re-entry path that survives reboots and is later reused by the double extortion crews ToyMaker sells access to.
