# MAL-2026-12335: Malicious code in aegis-runtime (npm)


- **Type:** Malicious package
- **Package:** `aegis-runtime` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12335?

MAL-2026-12335 is a malicious package in aegis-runtime, published on 5 Aug 2026. 

### Official description

The package's declared postinstall hook runs `node src/test.js`, which issues an HTTPS GET to https://workconfig.vercel.app with TLS certificate validation disabled (`rejectUnauthorized: false`) and passes the response body to `new Function('require', data.toString())(require)`, executing the fetched payload with access to the installer's `require` at `npm install` time. The destination is a mutable, non-registry, non-publisher host unrelated to the package's advertised purpose. Package metadata presents the module as a Node.js runtime monitoring and diagnostics toolkit and lists the placeholder author `Your Name`; the postinstall behavior is unrelated to the advertised monitor sources.

## What should I do about MAL-2026-12335?

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