## What is MAL-2026-10401?

MAL-2026-10401 is a malicious package in @espn-ping/react-dmed-oauth, published on 13 Jul 2026. 

### Official description

@espn-ping/react-dmed-oauth@666.0.0 declares a preinstall lifecycle script (`node index.js > /dev/null 2>&1`) that automatically executes on `npm install`. index.js shells out via child_process.exec to collect the installer's hostname, current working directory, username, and public IP (via `curl https://ifconfig.me`), then transmits the encoded data via `curl -k` GET to `https://r.dontvisitmy.website/sendreq.php?newdata=...`. Output is suppressed to hide the beacon from the installer's console. The scope `@espn-ping` and version `666.0.0` are consistent with a dependency-confusion beacon targeting an internal ESPN/Disney namespace.

## What should I do about MAL-2026-10401?

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