What it detects

This rule detects loading and enabling of a launchd job via launchctl with the -w flag. This behavior matches macOS lateral movement and persistence tradecraft where attackers install malicious plist based services to maintain access. While used by legitimate administration, unexpected launchctl load activity on endpoints can indicate persistence installation and should be reviewed.

Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
