This rule identifies "impossible travel" scenarios where a user logs in from two geographically distant locations within a short period (less than 2 hours). This can indicate a compromised account being used by an attacker, potentially leveraging VPNs or other proxy services to obscure their true location.
Detects the execution of the TruffleHog secret scanning tool. This tool is often used by attackers to find sensitive information like credentials in various data sources (filesystems, Git repositories, cloud storage, etc.). This rule identifies the process creation of TruffleHog and categorizes the type of scan being performed. It includes exclusions for legitimate CI/CD environments or security scanners.
Detects when an a role is modified or deleted in Google Workspace.
Detects when a firewall rule is modified or deleted in Google Cloud Platform (GCP).
Detects when an an application is removed from Google Workspace.
Detects a login attempt in Google Workspace flagged as a potential attack by a government-backed threat actor
Detects when an access level is changed for a Google workspace application.
An access level is part of BeyondCorp Enterprise which is Google Workspace's way of enforcing Zero Trust model.
An adversary would be able to remove access levels to gain easier access to Google workspace resources.

Detects when multi-factor authentication (MFA) is disabled.
Detects when an a role privilege is deleted in Google Workspace.
Detects when an Google Workspace user is granted admin privileges.
Detects automatic email forwarding to external domains in Google Workspace, which may indicate data leakage or misuse.
Detects the deployment of workloads that are deployed by using the break-glass flag to override Binary Authorization controls.
Identifies when an admission controller is executed in GCP Kubernetes.
A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server.
The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster.
An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster.
For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod. An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials.
An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.

Detects when an API access service account is granted domain authority.
This rule detects activity associated with TruffleHog, an open-source tool used for finding credentials and sensitive data, within cloud audit logs. It specifically looks for the 'trufflehog' string in the user_agent field, indicating that the tool was used to interact with cloud resources.
Detects a Python-initiated process attempting to read Google Cloud Platform (GCP) credentials by looking for command-line arguments containing 'GOOGLE_APPLICATION_CREDENTIALS' and 'cat 2>/dev/null'. This behavior is indicative of credential harvesting, potentially related to supply chain compromises like the Trivy incident.
Detects exploitation attempts of CVE-2026-21962 (Critical - CVSS 10.0) in Oracle WebLogic Server Proxy Plug-in. The vulnerability allows unauthenticated attackers to bypass access controls via path traversal (patterns like /_proxy/ or /wl_proxy/ + weblogic/..; + ProxyServlet) and header spoofing (WL-Proxy-Client-IP pointing to localhost/127.0.0.1). Successful exploitation can lead to unauthorized access, data modification or full compromise of the backend WebLogic Server.
Detects BigQuery queries using CONCAT with CHR functions to dynamically build cross-project paths, bypassing dot filters. High-fidelity indicator of LeakyLooker-style SQL injection.
Detects when a user authorizes the 'ToogleBox Recall' Google Workspace add-on. This tool has been observed being used by threat actors like UNC6661 (associated with ShinyHunters) to automate the deletion of MFA enrollment notifications, hiding unauthorized device registrations.
Detects attempts to exploit a vulnerability in Google Looker (CVE-2025-12743) by using error-based SQL injection within LookML dimension definitions. Attackers can use this to exfiltrate the internal Looker database.
Detects strong indicators of a successful device code phishing attack.
