Impair Defenses: Disable or Modify Tools

ID Name
T1629.001 Prevent Application Removal
T1629.002 Device Lockout
T1629.003 Disable or Modify Tools

Adversaries may disable security tools to avoid potential detection of their tools and activities. This can take the form of disabling security software, modifying SELinux configuration, or other methods to interfere with security tools scanning or reporting information. This is typically done by abusing device administrator permissions or using system exploits to gain root access to the device to modify protected system files.
