What it detects

This rule detects execution of the Kraken ransomware encryptor with its characteristic key, path, timeout and directory command-line switches. The binary encrypts victim files and appends the .zpsc extension while dropping a ransom note. Detecting the encryptor invocation provides a late-stage indicator of active ransomware deployment.
