Disable or Modify Tools
Where this stands
No Sigma rule can address this — the telemetry MITRE names has no Sigma logsource behind it.
Sigma has no logsource taxonomy for mobile platforms. MITRE's telemetry here is mobile EDR and device APIs, which no Sigma rule can address.
What the technique is
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.

Correlates (1) application acquisition or use of elevated control paths capable of altering defensive tooling or protected system state, such as device administration, root-enabled modification, or security-setting manipulation, (2) direct changes to security-tool configuration, service state, package state, or protected enforcement settings such as SELinux-relevant files or security-app components, and (3) immediate degradation, suppression, or disappearance of expected security telemetry while the device and initiating application remain active.
