status: stable
description: This rule detects the execution of an AnyDesk binary with a version prior to 8.0.8. Prior to version 8.0.8, the Anydesk application used a signing certificate that got compromised by threat actors. Use this rule to detect instances of older versions of Anydesk using the compromised certificate This is recommended to avoid adversaries abusing the certificate and signing their binaries to bypass detections.
