Detection: GPG Key Created
Overview
Detect when a new GPG key is created in a GitHub account. GPG keys are typically used for commit signing, but attackers may add their own keys to impersonate trusted developers, bypass integrity checks, or evade detection through seemingly valid signed commits. Monitoring these events helps ensure the integrity of code contributions and detect potential account compromise.

Usage
Run the detection in your terminal:
powerpipe detection run github_security_log_detections.detection.gpg_key_createdSnapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe detection run github_security_log_detections.detection.gpg_key_created --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 = 'gpg_key.create'order by tp_timestamp desc;
