This rule identifies developer or contractor workstations that have Node.js/npm installed but currently lack active EDR sensor coverage (i.e., the sensor is either not onboarded or not in an active state). It employs a 24-hour grace period to filter out transient onboarding issues and ensures that the device has reported activity within the last 7 days to avoid alerting on decommissioned hardware. This gap in visibility increases the risk of undetected supply-chain malware execution and credential theft on sensitive developer endpoints.
Detects anomalous credential retrieval activity occurring within 30 minutes of a GitLab Duo Chat GraphQL subscription request. This pattern is indicative of potential exploitation of CVE-2026-87719, which involves insecure deserialization within the GitLab EE GraphQL subscription serializer to facilitate unauthorized credential access.
Detects anomalous serialized object payloads within authenticated GraphQL subscription requests to GitLab Duo Chat endpoints. This pattern is indicative of exploitation attempts targeting the insecure deserialization vulnerability in GitLab EE (CVE-2026-87719), where malicious payloads are injected into serialized data streams.
Detects unauthenticated path traversal attempts targeting the GitLab repository commits API, specifically checking for URL-encoded and plain path traversal patterns (e.g., '../') in requests to the commits endpoint. This behavior is indicative of attempts to exploit vulnerabilities like CVE-2026-85706 to read arbitrary files outside the repository scope.

This behavior is indicative of attempts to exploit vulnerabilities like CVE-2026-85706 to read arbitrary files outside the repository scope.
Detects the execution of Python interpreters with command-line arguments referencing files commonly used for proxy configurations, such as 'verify3.py', 'proxy_tester', or various '.txt' files located within a '/root/proxy/' directory. This pattern is indicative of potential proxy testing, configuration, or usage of custom proxy-based command-and-control tools.

Detects Java-based Metasploit/Meterpreter payload files (.class/.jar) dropped post-exploitation, as observed following PaperCut RCE exploitation chain
Detects instances where a development-oriented web server (such as Vite or Node.js) is configured to bind to all network interfaces ('0.0.0.0') and is simultaneously receiving inbound connections from non-private, external IP addresses on a common development port (5173). This rule filters out common CI/CD environments to focus on potentially insecure exposure of development tools to the public internet.
Detects attempts to access sensitive files like environment variables (.env), cloud provider credentials (AWS/Azure), or Terraform state files via a web server interface, specifically targeting Vite development server deployments.
Detects an exploitation attempt against the Vite Development Server (CVE-2026-39364) where an attacker uses specific query parameters to bypass file access restrictions and disclose sensitive files. The rule triggers on GET requests containing suspicious import-related query parameters and checks the resulting response to ensure a successful 200/206 status code and non-HTML content type.

CloudSEK researchers uncovered BigBear 2.0, a global Microsoft 365 phishing-as-a-service operation targeting hundreds of organizations across 40+ countries. The investigation exposed the attacker’s admin panel, affiliate network, phishing infrastructure, and thousands of stolen credentials and session cookies, revealing how modern AiTM attacks can hijack authenticated sessions even after MFA.
