Detects a suspicious pattern where an AI coding agent or user creates a public GitHub repository with specific naming conventions (e.g., 'sweeper-demo', 'gitshot-images') and subsequently pushes content containing sensitive terms like 'screenshot' within a short timeframe. This behavior is indicative of potential data exfiltration of internal development screenshots to a public repository.
Detects evidence of the SCKit supply chain worm within GitHub Actions CI pipelines. The rule identifies attempts to poison the build process by injecting a BASH_ENV path into GITHUB_ENV, which forces the execution of a malicious script (sckit-publish-bridge.sh) during subsequent shell steps. This script is designed to exfiltrate npm publishing credentials (NODE_AUTH_TOKEN) to external infrastructure. The detection logic covers both the injection mechanism and diagnostic output indicators from the bridge script.
Detects the GitHub Actions runner executing the Bun runtime to run a hidden index.js payload, specifically associated with the compromised 'actions-cool/issues-helper' or 'actions-cool/maintain-one-comment' actions. The rule filters for process execution context tied to GitHub runner internals and validates that the Bun execution follows the pattern observed in these supply chain attacks.
Detects anomalous GitHub audit log activity indicative of a potential supply-chain compromise. The rule identifies workflows or automated entities (Bot/App) that access sensitive Action secrets followed by the publishing of packages to public registries like PyPI or npm. This activity can represent the precursor steps of token-theft-driven malicious package injection.
Detects anomalous cloud authentication activity where an OIDC provider is created or its thumbprint is updated, followed by an 'AssumeRoleWithWebIdentity' call originating from a GitHub Actions subject claim that does not match authorized repository or branch patterns. This often indicates an adversary abusing OIDC trust relationships to gain unauthorized access to high-privileged roles, frequently linked to subsequent IAM policy modifications like 'setIamPolicy' in GCP to grant persistent 'owner' access.
Detects rapid mass-cloning or downloading of private GitHub repositories shortly after an OAuth token authorization, originating from IP addresses or countries not previously associated with the user account. This behavior is indicative of unauthorized bulk data extraction using compromised credentials, consistent with threat actor activity (e.g., TeamPCP/UNC6780).
Detects malicious BASH_ENV injection within GitHub Actions CI pipelines originating from the compromised sckit_poetry_build.py build backend. The injection, which targets GITHUB_ENV to introduce a malicious _pypi_bridge.sh script, is used to intercept PyPI publishing tokens during build processes, characteristic of the MemTensor/sckit supply chain attack.
Detects the creation or exposure of public repositories, releases, or gists under a personal GitHub account that utilize naming conventions associated with the 'PixelLeak' workaround. This technique allows adversaries to make previously private screenshots, recordings, or internal assets publicly accessible by hosting them in public personal repositories or releases.

This rule detects GitHub Actions workflows that explicitly reference specific 'actions-cool' GitHub actions using a known-bad mutable version tag ('@v2.2.1'). This tag corresponds to malicious code introduced into these repositories, allowing for potential CI/CD pipeline poisoning and supply chain compromise.
This rule monitors for unauthorized changes to GitHub Actions workflows that involve release or publishing processes, specifically looking for indicators of supply chain compromise like the introduction of 'id-token: write' or changes to publish scripts. It correlates these modifications with subsequent workflow executions and npm registry publish events attributed to the same actor to identify potential account takeover and malicious package distribution.
Detects the addition of new members to a GitHub organization or team outside of standard business hours. This behavior is correlated with potential subsequent grants of repository administrative access or read access to secrets, characteristic of attacker patterns attempting to gain unauthorized access to cloud environments and OAuth tokens via CI/CD pipelines or VCS platforms.
Detects anomalous engineering account activity associated with supply-chain compromise, specifically identifying the generation of access tokens or retrieval of secrets followed by unauthorized changes to CI/CD pipeline configurations or secret stores in platforms like GitHub, JFrog Artifactory, or BrowserStack.

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.
Detects the deletion of GitHub workflow logs that occur in close temporal proximity to sensitive operations such as secret access or package publication. The rule also flags deletions associated with workflow names containing AI-themed keywords, which may indicate an attempt to conceal malicious automation or activity.
Detects suspicious force push events to the 'main' branch in GitHub repositories. The rule flags pushes that include hardcoded commit hashes associated with known malicious activity, pushes where the author and committer identities do not match, or pushes containing specific indicators such as 'indexe.cjs' or 'preinstall' scripts which are common in software supply chain attacks.
Detects the GitHub Actions runner executing the Bun runtime to run a hidden index.js payload, specifically associated with the compromised 'actions-cool/issues-helper' or 'actions-cool/maintain-one-comment' actions. The rule filters for process execution context tied to GitHub runner internals and validates that the Bun execution follows the pattern observed in these supply chain attacks.
