Identifies rapid dropping of many distinct files deep within the .npm/_npx/ directory structure, a precursor to worm execution. This rule specifically looks for more than 20 distinct file creations within a 5-minute window in paths matching the regex ".npm[\]_npx[\][0-9a-fA-F]+".

Detects the command line sequence used by Miasma to restore passwordless sudo for the 'runner' user in GitHub Actions by overwriting sudoers via a Docker container. This specific sequence involves echoing 'runner ALL=(ALL) NOPASSWD:ALL' into a file within the /mnt/runner directory and then changing its permissions to 0440, indicative of a privileged modification to the sudoers file within a containerized GitHub Actions runner environment.

Detects creation, modification, or renaming of 'help.php' within a REDCap application path. This activity is indicative of a web shell deployment, as observed by GTIG with UNC6508 using 'help.php' for persistence and payload uploads. The combination of the campaign-specific filename and REDCap path provides a high-confidence signal.

Detects PHP or web server processes launching command-line database clients. INFINITERED collected database credentials and supported arbitrary SQL execution against compromised REDCap environments. Direct database-client execution by a web-serving process is uncommon and may indicate credential access, data collection, or backdoor command execution.

This rule detects when a child process of npm (node, bun, or npm itself) reads a Kubernetes service account token file. This activity can indicate a compromised package attempting to access internal Kubernetes clusters from a developer's machine. Such an event warrants investigation into recent software installations or user activity, and engagement with the security team if the cause is unclear.

Detects a compiled Python extension writing .py or .pyc files into a temporary or profile directory for later execution. This behavior is often associated with malware that uses Python for its runtime logic, where the compiled Python code (e.g., from Cython) extracts and drops the actual Python scripts for execution.

This activity is indicative of the InvisibleFerret malware (also known as Void DoKkaebi or BeaverTail) which uses such launchers to import newly downloaded .pyd or .so extensions and supply runtime connection arguments.
