# MAL-2026-10680: Malicious code in syncgrove (npm)


- **Type:** Malicious package
- **Package:** `syncgrove` (npm)
- **Published:** 15 Jul 2026

## What is MAL-2026-10680?

MAL-2026-10680 is a malicious package in syncgrove, published on 15 Jul 2026. 

### Official description

The package's postinstall lifecycle script contacts a hardcoded plain-HTTP endpoint at http://player.sweeprovider.org, retrieves a key via /getKey.php and an AES-CBC encrypted payload via /generateRandomKey.php, decrypts the payload using CryptoJS with a hardcoded key suffix, and passes the resulting string to child_process.exec. This causes attacker-supplied, mutable, obfuscated shell content to run automatically on the installer's machine during `npm install`. The package's README presents it as a trivial 'greet' module, which does not match the actual install-time behavior. The remote host is unauthenticated and served over plain HTTP, so the fetched command body is both attacker-mutable and MITM-modifiable.

## What should I do about MAL-2026-10680?

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