According to data from URLhaus, winlocker executables have high detection rates. One sample hosted on GitHub achieved a across multiple antivirus engines when scanned.

Unlike advanced ransomware that targets enterprise networks with sophisticated asymmetric encryption, Winlockers are structurally rudimentary. They primarily focus on visual extortion by hijacking the Windows Desktop Window Manager (DWM), disabling system recovery tools, and forcing a ransom screen to overlay all other windows.

Use robust anti-malware and Endpoint Detection and Response (EDR) solutions that can detect unauthorized encryption behavior, not just known signatures.
