Query: what is T1569
Matching passage: T1569 System Services. Tactics: execution. Description: Adversaries may abuse system services or daemons to execute commands or programs. Adversaries can execute malicious content by interacting with or creating services either locally or remotely. Many services are set to run at boot, which can aid in achieving persistence ([Create or Modify System Process](https://attack.mitre.org/techniques/T1543)), but adversaries can also abuse services for one-time or temporary execution.
Near-miss passage: T1569.001 Launchctl. Tactics: execution. Description: Adversaries may abuse launchctl to execute commands or programs. Launchctl interfaces with launchd, the service management framework for macOS. Launchctl supports taking subcommands on the command-line, interactively, or even redirected from standard input.(Citation: Launchctl Man) Adversaries use launchctl to execute commands and programs as [Launch Agent](https://attack.mitre.org/techniques/T1543/001)s or [Launch Daemon](https://attack.mitre.org/techniques/T1543/004)s. Common subcommands include: <code>launchctl load</code>,<code>launchctl unload</code>, and <code>launchctl start</code>. Adversaries can use scripts or manually run the commands <code>launchctl load -w "%s/Library/LaunchAgents/%s"</code> or <code>/bin/launchctl load</code> to execute [Launch Agent](https://attack.mitre.org/techniques/T1543/001)s or [Launch Daemon](https://attack.mitre.org/techniques/T1543/004)s.(Citation: Sofacy Komplex Trojan)(Citation: 20 macOS Common Tools and Techniques)
