SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

PolinRider is a DPRK/Lazarus supply-chain malware that targets JavaScript and Node.js developers by infecting build config files, malicious npm packages, and VS Code droppers to exfiltrate credentials, crypto assets, and propagate via git force-pushes. This Skill provides a comprehensive, no-dependency scan to identify active infections, residual indicators of compromise (IOCs), and propagation artifacts on both local project directories and entire global systems.

Core Features & Use Cases

  • Active threat detection: Identifies running malware processes and live C2 connections to catch ongoing exfiltration in real time.
  • Comprehensive IOC scanning: Checks source code, build configs, build caches, VS Code tasks, fake binary payloads, git hooks, and installed npm packages for known PolinRider signatures.
  • Guided remediation: Provides step-by-step instructions to kill active threats, clean infected files, remove propagation scripts, and rotate compromised credentials.
  • Use case: If you installed an affected npm package or used a compromised VS Code extension between March and April 2026, run this scan to confirm if your machine or projects are infected.

Quick Start

Trigger a scan by asking Claude to scan for PolinRider locally to check your current project, or scan for PolinRider globally to check your entire home directory.

FAQPage Schema
How do I scan my Node.js project for PolinRider supply-chain malware?

You can scan for PolinRider malware by triggering a local scan to check your current project directory, or a global scan to check your entire home directory for active threats, residual IOCs, and propagation artifacts.

What is PolinRider malware and how does it compromise JavaScript development environments?

PolinRider is a DPRK/Lazarus supply-chain malware that targets JavaScript and Node.js developers by infecting build configs, malicious npm packages, and VS Code droppers to exfiltrate credentials, crypto assets, and propagate via git force-pushes.

How do I detect active malware C2 connections and malicious npm packages on my system?

To detect active malware C2 connections and malicious npm packages, run a scan that identifies running malware processes, live C2 endpoints, known obfuscation signatures, VS Code droppers, and fake binary payloads using standard built-in system utilities.

Can I check for PolinRider infections without installing additional security dependencies?

Yes, you can check for PolinRider infections without dependencies because the scan uses only standard built-in system utilities to identify active threats, compromised VS Code extensions, and tampered build configs.

How do I remove PolinRider persistence mechanisms and rotate compromised credentials?

To remove PolinRider persistence mechanisms and rotate compromised credentials, follow the scan's guided remediation instructions to kill active threats, clean infected files, remove propagation scripts, and execute credential rotation.

When should I scan for PolinRider if I installed npm packages or VS Code extensions recently?

You should scan for PolinRider if you installed an affected npm package or used a compromised VS Code extension between March and April 2026, to confirm whether your machine or projects are infected.
