## What is MAL-2026-12067?

MAL-2026-12067 is a malicious package in hwi-lib, published on 5 Aug 2026. 

### Official description

hwi-lib@1.0.1 ships an empty index.js and a postinstall script that runs automatically on npm install. The script reads installer credential files (~/.aws/credentials, ~/.ssh/id_rsa, id_ed25519, id_ecdsa, ~/.npmrc, ~/.gitconfig, ~/.config/solana/id.json, ~/.ethereum/keystore,.env variants) and walks hidden subdirectories of the user's home directory reading any file matching wallet|key|secret|seed|mnemonic|keystore|private or ending in.json/.pem/.key. The collected contents are POSTed via https.request to the hardcoded endpoint https://enxhcjpo5ev.x.pipedream.net/c. Package name and 'crypto utility' description impersonate the HWI (Hardware Wallet Interface) tooling while the shipped module exports nothing, indicating a lure.

It is considered malicious because:

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