# MAL-2026-6253: Malicious code in zomato-server (npm)


- **Type:** Malicious package
- **Package:** `zomato-server` (npm)
- **Published:** 21 Jun 2026

## What is MAL-2026-6253?

MAL-2026-6253 is a malicious package in zomato-server, published on 21 Jun 2026. 

### Official description

The package's package.json declares a preinstall lifecycle hook that runs curl to POST the installer's hostname, whoami, current working directory, and a base64-encoded dump of the full process environment to http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site over plain HTTP. The destination is an Interactsh-style out-of-band collection subdomain unrelated to any legitimate Zomato infrastructure. This fires automatically on `npm install` without user consent, leaking any credentials, tokens, or secrets present in environment variables (CI tokens, npm auth, AWS keys, etc.). The package itself ships only a 62-byte stub index.js exporting { name, version } and impersonates the Zomato brand (description 'Zomato server-side utilities', repo pointing at github.com/zomato/zomato-server), consistent with a dependency-confusion lure targeting Zomato internal builds.

The OpenSSF Package Analysis project identified 'zomato-server' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

- The package executes one or more commands associated with malicious behavior.

## What should I do about MAL-2026-6253?

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