What it detects

This rule detects download of the lockd ransomware binary into a hidden temp directory, the staging step of the evolved JADEPUFFER campaign built to destroy AI models. The actor writes the encryptor to a concealed path before execution. This named artifact in a hidden directory is a strong ransomware deployment indicator.
