What it detects

This rule detects use of the built-in security utility to dump the keychain or extract stored generic and internet passwords, a credential-access behavior used by macOS stealers to harvest saved secrets. Credential theft from the keychain supports the infostealer activity documented in the Red Canary Threat Detection Report. Because interactive keychain dumping is uncommon, detecting these security-command patterns surfaces credential harvesting.
