Detects Node.js processes executing suspicious command lines that involve fetching and executing remote JavaScript code. This behavior is indicative of a loader or downloader script commonly used to pull and evaluate malicious payloads at runtime, specifically referencing indicators associated with 'GHAPPIER'.
Detects the presence of the malicious 'indexed-btree' npm package, which contains a backdoor that hooks 'BTree.prototype.set' to execute 'sharedLoad.min.js' at runtime. The rule monitors for characteristic file paths, function hooking patterns, and node process spawning behavior designed to evade installation-time static analysis.
Detects instances where a parent Node.js process spawns a child Node.js process using a command line structure often associated with malicious npm packages. These packages frequently attempt to execute loader scripts in a detached or background manner to evade detection while maintaining persistence or performing malicious operations.
Detects instances where a Node.js process spawns another Node.js process as a child. This behavior is often associated with malicious npm packages attempting to evade detection during runtime execution or executing secondary malicious payloads.
Detects the GHAPPIER loader identified across 65 public npm/GitHub repositories and 22 developer accounts, based on its embedded remote-fetch/eval pattern and campaign markers
This rule detects the presence of the malicious indexed-btree npm package by searching for its obfuscated runtime loader triggered via BTree.prototype.set. The malware attempts to spawn a detached Node.js process to execute a secondary payload (sharedLoad.min.js) instead of relying on standard installation scripts, allowing it to maintain persistence and bypass simple static analysis.
Detects the 'sharedLoad.min.js' loader script associated with the malicious 'indexed-btree' npm package family. This script utilizes X25519 ECDH for key exchange and AES-256 decryption to retrieve and execute a second-stage payload hosted on a Sepolia smart contract.
Detects Node.js processes executing command lines containing known malicious indicators or accessing specific suspicious JavaScript files (e.g., sharedLoad.min.js) associated with malicious loaders or hardcoded cryptographic keys.
Detects the sharedLoad.min.js obfuscated first-stage loader dropped by the malicious npm indexed-btree package, triggered via BTree.prototype.set to evade static/taint-analysis scanners
Detects the sharedLoad.min.js obfuscated first-stage loader dropped by the malicious npm indexed-btree package, triggered via BTree.prototype.set to evade static/taint-analysis scanners
Detects the sharedLoad.min.js obfuscated first-stage loader dropped by the malicious npm indexed-btree package, triggered via BTree.prototype.set to evade static/taint-analysis scanners
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.
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.
Detects the execution of 'git checkout' commands involving 'FETCH_HEAD', initiated by Gemini or Node.js runtime environments. This pattern may indicate automated repository synchronization, potential software supply chain activity, or anomalous usage of developer tools.
Detects the execution of the 'sckit' Go implant, a malicious binary associated with trojanized '@memtensor/memos-cloud-openclaw-plugin' or 'MemoryOS' packages. The rule identifies instances where this binary is spawned as a child process of a language runtime (Node.js or Python) when the execution originates from specific directory paths associated with these packages, or when the parent process command line indicates these packages are being initialized.
Detects BeaverTail JavaScript-based loader malware hidden inside NPM packages, distributed via GitHub or Bitbucket during fake technical interviews
This rule detects suspicious activity where a node.exe process, often associated with a node-pty terminal emulation, launches common Windows command-line shells (cmd.exe, powershell.exe) from specific file paths or directories. This behavior is indicative of a Node.js-based Remote Access Trojan (RAT) or shell spawning mechanism being used to establish command and control or persistence on a Windows host.
Detects the GHAPPIER four-stage malware loader, specifically targeting npm-based JavaScript files. The rule identifies malicious activity through specific artifacts including hardcoded C2 URLs (vercel.app domains), campaign markers, file paths, and eval-based execution patterns.
Detects npm package publishing events performed via GitHub Actions OIDC trusted publishing that occur without the use of a traditional npm token. This rule targets potentially unauthorized package releases triggered by automated CI/CD identities, which may indicate abuse of compromised workflows or misconfigured auto-publish settings.
Detects the obfuscated index.js payload bundled in the compromised actions-cool/issues-helper and actions-cool/maintain-one-comment commit a0c53dd42fc842d2f9276c5a1d4f9a26abe8713d, executed via 'bun run $GITHUB_ACTION_PATH/index.js'
