This detection rule identifies when Time Machine, Apple's automated backup service on macOS, is disabled using the native command line utility `tmutil`. This action can indicate malicious intent, as disabling backups can expose a system to data loss or prevent recovery from an attack. The rule monitors process creation events, specifically filtering for instances where the `tmutil` command is invoked with options that include 'disable'. It detects both the process name and command line arguments to distinguish malicious configurations from legitimate administrative operations. False positives may occur due to legitimate administrative activities, hence it's essential to incorporate additional context-awareness when interpreting alerts from this rule.
