MAL-2026-12068 Malicious code in ledger-lib (npm)

The npm package [email protected] presents itself as a Ledger hardware wallet library but ships no wallet functionality (index.js is empty). Its package.json declares a postinstall hook that runs postinstall.js on every npm install. postinstall.js reads a hardcoded list of installer-owned secret files including ~/.env variants, ~/.npmrc, ~/.aws/credentials, ~/.ssh/id_rsa, and ~/.ssh/id_ed25519, then enumerates dotdirectories under the user's home and reads any file whose name matches wallet, key, secret, seed, mnemonic, keystore, or private, truncating each to 8KB. The collected contents are POSTed via https.request to the hardcoded host enxhcjpo5ev.x.pipedream.net at path /c, a Pipedream request bin acting as the attacker's collection endpoint. The stated Ledger purpose is cover for credential and wallet-seed theft executed automatically at install time.
