Detects pull requests created in GitHub repositories by entities labeled as 'Bot', 'App', or 'integration', or containing the term 'codex', specifically targeting repositories where such entities have not performed these actions in the previous 30 days. This baseline approach identifies potentially hijacked or unauthorized automation accounts performing activities outside of their standard repository scope.

Detects instances where a user grants OAuth application permissions to GitHub or Slack shortly (within 30 minutes) after signing into a low-trust application (Discourse or OpenAI Community), suggesting a potential session hijacking or trusted-relationship abuse scenario where an attacker leverages an existing SSO session to authorize malicious applications.

This rule detects a user account performing its first-ever GitHub OAuth or repository access within a short timeframe (30 minutes) after authenticating to a designated low-trust OpenAI community forum. This pattern is designed to identify potential adversary activity where a compromised or newly created account is used to pivot from a low-trust environment to corporate repository access.

Detects GitHub OAuth authorization, repository cloning, or ZIP downloads from source IP addresses that have not been observed for the specific actor within the past 30 days. This rule helps identify potential account compromise or token theft where an attacker attempts to access repository data from a new location, while specifically excluding bot/service accounts known for rotating CI infrastructure IPs.

Detects GitHub repository actions (git.clone, oauth_authorization.create, repo.download_zip) from actor IPs not seen for that user in the prior 30 days, requiring either 3+ actions or activity across 2+ distinct repositories from the new IP within the same day. Aggregating to burst/multi-repo behavior (rather than alerting on a single new-IP event) filters out one-off false positives from travel, VPNs, or dynamic IP reassignment while still surfacing sustained anomalous access patterns consistent with account compromise or bulk exfiltration.

This rule detects potential cloud service enumeration activity originating from a specific, potentially malicious IP address (23.234.84.102). It flags instances where this source IP performs specific API calls ('GetCallerIdentity' and 'ListTopics') without expected user-agent strings typical of legitimate AWS service traffic.

Detects multiple AWS API calls (Publish, GetCallerIdentity, ListTopics) originating from a specific IP address (23.234.84.102) associated with a Zapier SNS sender. This rule monitors for potentially unauthorized or anomalous API usage patterns by identifying repeated, successful, and non-error events from a known source that may indicate misuse or compromise of an integration account.

Detects instances where a removed GitHub organization member performed bulk repository access (cloning or downloading) shortly before their removal, potentially indicating exploitation of retained access by a departed employee or an adversary using a valid account before deprovisioning. The rule identifies activity occurring more than 24 hours prior to removal involving multiple repositories or multiple access actions.
