# MAL-2026-17302: Malicious code in solidity-lock (npm)


- **Type:** Malicious package
- **Package:** `solidity-lock` (npm)
- **Published:** 30 Sep 2026

## What is MAL-2026-17302?

MAL-2026-17302 is a malicious package in solidity-lock, published on 30 Sep 2026. 

### Official description

The package's declared main index.js is a trivial no-op Express middleware whose only real effect is to require('./lib/config'), a ~4 MB obfuscator.io-style bundle (rotating string array, hex-escaped entries, self-executing IIFE) that runs at import time. Package identity does not match the shipped code: package.json name is 'solidity-lock' with a vulnerability-management description, keywords advertise a logger ('fast','logger','stream','json'), scripts are 'smoke:pino'/'smoke:file', the README is a copy of pino's README with the name changed, and index.d.ts references pinojs/pino — three inconsistent cover stories layered over the opaque payload. axios ^1.10.0 is declared as a dependency but is not referenced anywhere in the plain-text sources; the only plausible consumer is the obfuscated blob, consistent with outbound HTTP from the hidden payload. Any process that requires this package executes the obfuscated bundle in-process with full host privileges.

## What should I do about MAL-2026-17302?

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