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 Agents or Launch Daemons. 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 Agents or Launch Daemons.(Citation: Sofacy Komplex Trojan)(Citation: 20 macOS Common Tools and Techniques)
Detection Strategy for System Services: Launchctl
User Account Management: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures:
Enforcing the Principle of Least Privilege
Implementing Strong Password Policies
Managing Dormant and Orphaned Accounts
Account Lockout Policies
Multi-Factor Authentication (MFA) for High-Risk Accounts
Restricting Interactive Logins
Tools for Implementation
Built-in Tools:
Identity and Access Management (IAM) Tools:
Privileged Account Management (PAM):
