What it detects

This rule detects execution of the lockd encryptor with its lock argument, the encryption stage of the evolved JADEPUFFER ransomware that targets AI model files. The binary encrypts data and appends a locked extension across the host. Its invocation is a high-confidence sign of in-progress ransomware impact.
