Detection: GPG Key Deleted

Overview

Detect when a GPG key is removed from a GitHub account. While this may be part of normal key rotation, attackers may delete trusted GPG keys to prevent legitimate developers from signing commits or to replace them with their own keys. Monitoring these events helps ensure the authenticity of code contributions and detect potential tampering.

Usage

Run the detection in your terminal:

powerpipe detection run github_security_log_detections.detection.gpg_key_deleted

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe detection run github_security_log_detections.detection.gpg_key_deleted --share

SQL

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_log
where
  action = 'gpg_key.destroy'
order by
  tp_timestamp desc;
