What it detects

This rule detects execution of the Lynx ransomware binary using its distinctive command-line flags that control network-share encryption, drive mounting, process termination, and wallpaper behavior. Adversaries run the encryptor with these parameters to maximize impact across a compromised environment, making early detection critical for interrupting encryption before widespread data loss.
