# MAL-2026-10728: Malicious code in bvm-core (npm)


- **Type:** Malicious package
- **Package:** `bvm-core` (npm)
- **Published:** 16 Jul 2026

## What is MAL-2026-10728?

MAL-2026-10728 is a malicious package in bvm-core, published on 16 Jul 2026. 

### Official description

dist/index.js in bvm-core@1.1.43 imports child_process and issues fetch() calls to the hardcoded host https://bvm-core.nexsail.top at the top of the bundled module, alongside a secondary fetch to registry.npmmirror.com. The combination — a lookalike domain that mirrors the package name on an unrelated TLD, module-load-time network calls, and child_process usage in the same bundle — is the fingerprint of an install/import-time beacon and command execution channel, not a legitimate SDK call. The package name resembles established `bvm` version-manager tooling but the code routes traffic to an author-controlled host on nexsail.top rather than to any documented registry or vendor endpoint.

## What should I do about MAL-2026-10728?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
