Potential macOS SSH Brute Force Detected

Identifies a high number of inbound SSH login attempts on a macOS host within a short time window. On macOS, each inbound SSH authentication attempt spawns the sshd-keygen-wrapper process once, whether the login succeeds or fails. Adversaries may perform password brute force or password spraying against exposed SSH services to obtain unauthorized access.
