T1547.007 — Boot or Logon Autostart Execution: Re-opened Applications
Sub-technique of T1547 Boot or Logon Autostart Execution
Description
Adversaries may modify plist files to automatically run an application when a user logs in. When a user logs out or restarts via the macOS Graphical User Interface (GUI), a prompt is provided to the user with a checkbox to "Reopen windows when logging back in". When selected, all applications currently open are added to a property list file named com.apple.loginwindow.[UUID].plist within the ~/Library/Preferences/ByHost directory. Applications listed in this file are automatically reopened upon the user’s next logon.
Adversaries can establish Persistence by adding a malicious application path to the com.apple.loginwindow.[UUID].plist file to execute payloads when a user logs in.

This project's own SigmaHQ-derived detection pipeline tags every compiled rule with the ATT&CK technique(s) it maps to -- if a rule in your install covers this technique, it shows up automatically on your own Grafana Alerts dashboard's "Top ATT&CK Techniques" panel, no lookup needed. This page exists so a click from there always lands here on easysiem.com, not on attack.mitre.org.
