Source: amazon-inspector (0b6dec4d715e2863e7f55749d6d2a390926f3f2f1df62e4de223c6acc818632d)

The package runs a bootstrap from both its install lifecycle script (node index.js) and its main module that invokes an obfuscated probe. The probe reads os.userInfo().username, os.hostname(), and the basename of process.cwd(), concatenates them with a static tag (bxcfg) and a timestamp, and performs a dns.resolve4 lookup against <tag>.<user>.<host>.<cwd>.<ts>.oob.algamil7x.xyz, exfiltrating installer identity over DNS to a non-first-party domain unrelated to the claimed baanx publisher. The exfil host and the os/dns/userInfo/hostname/cwd/resolve4 API references are hidden in String.fromCharCode/hex-decoded byte arrays in probe/impl.js and sibling files e9c3a6.js / f0d4b7.js, and the os and dns modules are loaded through module.constructor._load with decoded name arrays to defeat static analysis. Behavior fires automatically on npm install and on require('@baanx/blockchain-config').
