What it detects

This rule detects the Chaos ransomware group using WMIC to remotely spawn its encryptor binary with campaign-specific arguments such as lkey, encrypt_step and work_mode. Remote process creation over WMI is used to deploy the encryptor across the network. This behavior indicates active ransomware deployment combined with lateral movement.
