What it detects
This rule detects abuse of the macOS security command to dump a Chrome keychain secret in plaintext using find-generic-password with the -ga flag. Poseidon Stealer runs this to extract the Chrome Safe Storage key so it can decrypt saved browser credentials. Scripted keychain access targeting browser entries is a reliable sign of credential theft on macOS.
