Detects rapid termination of specific mobile messenger applications (Max) within seconds of starting, while indicators of the Frida dynamic instrumentation tool are concurrently detected on the device. This pattern suggests the application is identifying the presence of a hooking/instrumentation environment and self-terminating as a defense mechanism. The detection is further correlated with failed connection attempts to the application's backend.

Detects the obfuscated first-stage JavaScript payload sharedLoad.min.js dropped by the malicious npm indexed-btree package, identified by string-array encoding and self-checksumming array rotation obfuscation patterns
Detects the indexed-btree npm malware loader embedded in BTree.prototype.set that spawns a detached hidden Node.js child process and references sharedLoad.min.js
Detects the execution of npm commands to install specific, potentially malicious or typo-squatted npm packages. The rule filters for common npm install command line arguments and matches against a predefined list of package names that are often associated with supply chain compromise attempts.

This rule detects potentially malicious child processes spawned by Node.js. It specifically monitors for scenarios where a Node.js process executes a detached child process using standard library options ('detached', 'stdio', 'windowsHide', 'ignore'), which is a common technique used by malware to run background tasks while remaining hidden from the parent process terminal. The rule excludes common benign development, build, and process management tools to reduce false positives.
This rule detects instances where a Node.js process spawns a child Node.js process from a 'node_modules' directory using configuration flags typically associated with hidden, detached background tasks (e.g., 'detached', 'stdio', 'windowsHide', 'ignore'). It explicitly excludes common Node.js process managers and build tools to reduce false positives associated with legitimate development activities.

Identifies Debian systems running vulnerable versions of the libheif package (versions 1.10.x through 1.21.x) that are susceptible to CVE-2026-32882. This rule uses software inventory data to detect installations requiring an upgrade to version 1.22.0 or higher.
