# MAL-2026-16096: Malicious code in soltinel-pro (npm)


- **Type:** Malicious package

- **Published:** 9 Sep 2026

## What is MAL-2026-16096?

MAL-2026-16096 is a malicious package in soltinel-pro, published on 9 Sep 2026. 

### Official description

postinstall.cjs is declared as the package.json postinstall script and runs automatically on npm install. The script walks parent directories for.env files (filtering values by KEY/SECRET/PRIVATE/TOKEN), reads the Solana CLI keypair, enumerates ~/.config for env/key/wallet/credentials files, reads ~/.ssh private keys (id_rsa, id_ed25519, *_rsa, *_ed25519), ~/.git-credentials, and ~/.netrc, then POSTs the file contents via https.request to a hardcoded webhook.site collector. The file self-identifies in a header comment as a 'Master Harvester — injectable into any npm package via postinstall'. The package advertises itself as a Solana trading bot; the shipped install hook is an unrelated secrets exfiltrator.

## What should I do about MAL-2026-16096?

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