# MAL-2026-10102: Malicious code in dc-repro (npm)


- **Type:** Malicious package
- **Package:** `dc-repro` (npm)
- **Published:** 9 Jul 2026

## What is MAL-2026-10102?

MAL-2026-10102 is a malicious package in dc-repro, published on 9 Jul 2026. 

### Official description

On `npm install`, postinstall.js issues an HTTP GET to a hardcoded bare-IP endpoint at http://130.49.177.51:18080/p/dc-20260627-yandex-geobase carrying the package name, version, and a campaign tag (`bb-yandex-geobase-20260627`). The beacon fires automatically as a lifecycle script with no user opt-in, confirming code execution inside the installer's environment and exposing the installer's source IP / network position to an attacker-controlled host over plain HTTP. The package additionally declares a dependency on `yandex-geobase` and labels its callback with that package name, consistent with a dependency-confusion probe targeting the `yandex-geobase` namespace. Installer impact: any machine that resolves and installs `dc-repro` silently emits a network callback to the hardcoded IP at install time.

## What should I do about MAL-2026-10102?

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