Detects anomalous, large-scale cloning or mirroring of code repositories combined with targeted access to infrastructure-as-code configuration files (e.g., .tfvars, .tfstate) or automated exfiltration of CI/CD build artifacts. This behavior is indicative of an adversary attempting to exfiltrate proprietary source code or sensitive secrets stored within repositories.
Detects high-frequency S3 object upload activity (PutObject/CompleteMultipartUpload) originating from the Rclone tool, a common indicator of potential data exfiltration to cloud storage.
This rule detects modifications to Group Policy Objects (GPO) or Microsoft Entra (formerly Azure AD) policies that weaken established security controls. For GPO, it monitors Event ID 5136 for changes to security-relevant attributes (e.g., disabling firewall or real-time monitoring) in Active Directory. For Entra, it monitors audit logs for administrative operations that reduce security posture, such as disabling MFA, lowering authentication trust, or deleting Conditional Access policies. It includes filters to exclude legitimate, documented change management activities.

Detects OAuth2 JWT bearer-grant token requests to Google's OAuth endpoint using the attacker-controlled service-account identity and Sheets API scope observed in the fake GlobalProtect campaign
Detects instances where the Grafana MCP (Model Context Protocol) server's service account identity executes administrative tools (such as 'grafana_api_request') within a session that lacks a verified, prior authentication event (bearer token). This pattern suggests an adversary may be spoofing or hijacking a privileged service account session to perform unauthorized administrative actions.
This rule detects activity associated with known indicators of compromise (IOCs) related to European political targeting campaigns. It monitors network, email, and authentication logs for connections to specific malicious domains (including .onion addresses) and IP addresses. The rule spans multiple data sources, including device network events, Entra ID sign-in logs, cloud application events, and email communications.
Detects a GitLab personal access token used from multiple distinct source IPs or from IPs associated with the leaked gitlab-triage token, inconsistent with expected CI runner infrastructure.
Detects unreviewed commits to .gitlab-ci.yml that alter how the gitlab-triage tool invokes the sensitive API_TOKEN variable, with no associated merge request.

Detects GitLab's personal_access_tokens/self endpoint being queried via GET, the reconnaissance step a leaked token uses to confirm its own scopes and privilege level.

Detects an Owner-role GitLab account or token modifying merge-request approval rules, protected-branch settings, or project membership -- controls that, if weakened, defeat code-review safeguards.
Detects the gitlab-triage automation tool being invoked with a personal access token scoped to the broad 'api' permission rather than a narrower issue/MR-only scope, inflating the blast radius if the token leaks.

Detects a single GitLab token/account holding Owner-level access across an unusually large number of projects (50+), the standing-privilege condition that turned one leaked token into a 55-project supply-chain exposure.
This rule monitors Office 365 SharePoint file operations and search queries for patterns indicative of automated discovery and exfiltration of sensitive content. It specifically identifies high-frequency search queries involving wildcard parameters used in SharePoint content indexing, which may suggest an adversary is systematically crawling or enumerating organizational documents.
Detects cloud application events originating from suspicious or specific User-Agent strings, including 'python-requests' and identified outdated or potentially spoofed Chrome versions (146, 150, 151.0.0). This behavior often correlates with automated scripts or bot activity interacting with cloud services.
