The 'MacOS Keyboard Events' detection rule is designed to identify potential key logger activity on macOS systems through analysis of keyboard events monitored by applications. Specifically, the rule utilizes osquery to track applications that are monitoring keyboard inputs. If an application is detected watching keyboard events, it generates an alert if it is not operating from an approved system path, which is indicative of potentially malicious software. The rule correlates with the MITRE ATT&CK framework under the tactic T1056, which focuses on input capture techniques. Validation tests assure that only unauthorized applications from unapproved paths will trigger alerts, thereby reducing false positives from legitimate applications and maintaining system integrity.
