Detection: MFA Factor Removed
Overview
Detect when a registered multi-factor authentication (MFA) factor (such as a TOTP app, SMS number, or hardware security key) is removed from a GitHub account. While this may occur during account updates or device changes, it can also indicate that an attacker is weakening account protections to maintain persistent access. Monitoring these events helps detect suspicious changes to MFA settings and protect account security.

Usage
Run the detection in your terminal:
powerpipe detection run github_security_log_detections.detection.mfa_method_removedSnapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe detection run github_security_log_detections.detection.mfa_method_removed --shareSQL
This detection uses a named query:
select tp_timestamp as timestamp,action as operation,concat('https://github.com/', user) as resource,actor,tp_source_ip as source_ip,tp_id as source_id,*exclude (actor, timestamp)
from github_security_logwhere action in ('two_factor_authentication.remove_factor')order by tp_timestamp desc;
