Description

Malicious code in @zzzcrypto/bitcoin-lib (npm)

Source: amazon-inspector

On require(), index.js serializes process.env together with hostname, username, homedir, platform, cwd, and a timestamp, base64-encodes the JSON, and sends it via HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id. A tmp flag file gates re-execution to reduce noise. The package name @zzzcrypto/bitcoin-lib and its README present it as a drop-in for bitcoinjs-lib, and the code attempts require('bitcoinjs-lib') to transparently proxy the real library's API when present so callers observe normal behavior; the internal identifier in the exfil payload is @wethenorth12/bitcoin-lib, and identifier names in the harvester are scrambled (kffr, xqyv, qzph, _h). Environment variables in developer and CI processes routinely contain credentials, API tokens, and cloud keys, so this constitutes credential and host-identity theft against any process that imports the package.
