What this malware does

chrome-enterprise-premium-mcp ships a postinstall lifecycle script that fires automatically on npm install and POSTs installer host metadata (os.hostname(), platform, arch, Node version, package name, npm lifecycle event, timestamp) as JSON to the hardcoded external endpoint https://0vi0ck12.instances.poc.jchunt.top/chrome-enterprise-premium-mcp. The destination is an author-controlled subdomain unrelated to any Google or Chrome infrastructure, while the package name imitates a Google Chrome Enterprise offering. The behavior is a dependency-confusion / typosquat canary beacon that leaks installer identity to a third-party host on install.

Detection & response playbook

Backdoor / remote access

  1. Find it

    Search your lockfiles and build artifacts for chrome-enterprise-premium-mcp (version 1.0.0).

  2. If you installed it — respond

    chrome-enterprise-premium-mcp establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If chrome-enterprise-premium-mcp was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
