Description
The AD FS service configuration file was modified.
Attacker's Goals
The attacker's goal is to establish a persistent, high-privilege backdoor by forcing the service to load a malicious configuration that enables remote code execution and the bypass of security controls like MFA.
Investigative actions
- Check if the AD FS service was stopped or restarted around the time of modification.
- Investigate the process and user that performed the write operation for signs of compromise.
