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.
