Detection: SSH Key Created

Overview

Detect when a new SSH key is added to a GitHub account. While SSH keys are commonly used to enable secure repository access, attackers may add their own keys to maintain persistence or gain unauthorized access. Monitoring these events helps identify unexpected credential additions and reduce the risk of account compromise.

  tp_timestamp as timestamp,
action as operation,
fingerprint as resource,
actor,
tp_source_ip as source_ip,
tp_id as source_id,
*
exclude (actor, timestamp)

from
  github_security_log
where
  action = 'public_key.create'
order by
  tp_timestamp desc;
