This package implements a classic Contagious Interview / chai-max DPRK/Lazarus staged payload loader. The entrypoint (index.js) auto-initializes on import, spawning a detached background process via init.js with suppressed stdio and windowsHide:true to evade detection. loader.js fetches base64-encoded code from the npoint.io C2 endpoint (https://api.npoint.io/641d37178a880b1e8b8f), decodes it, and executes it via `new Function("require", "__dirname", "__filename", "module", "exports", decodedCode)` — a full remote code execution primitive with access to the Node.js runtime. The Module.prototype.require monkey-patching is a known chai-max technique to intercept child_process calls cross-platform (Win32/Unix), ensuring payload execution works silently on both platforms. The publisher account is less than an hour old, has one package, and no repository — all consistent with a throwaway attacker account.
