Adversaries may gain persistence and elevate privileges by executing malicious content triggered by the Event Monitor Daemon (emond). Emond is a Launch Daemon that accepts events from various services, runs them through a simple rules engine, and takes action. The emond binary at `/sbin/emond` will load any rules from the `/etc/emond.d/rules/` directory and take action once an explicitly defined event takes place.
If this is happening now
Checklists and playbooks to open while the alert is still live.
Suspicious execution on an endpoint
An EDR alert, an unexplained process, or a user reporting something odd.
Cloud account compromise
Impossible travel, an unrecognised inbox rule, or a reported invoice-fraud attempt.
how MITRE says to see it
Detection Strategy for Event Triggered Execution via emond on macOS
- Detection focuses on identifying unauthorized file creation or modification within `/etc/emond.d/rules/` or `/private/var/db/emondClients`, which indicate attempts to register a malicious emond rule.
what reduces it
- M1042 Disable or Remove Feature or Program. Consider disabling emond by removing the Launch Daemon plist file.
