banana-stand@9.9.11

Summary

On npm install, the package's install lifecycle hook runs node index.js, which loads lib/core.js. That module reads os.userInfo().username, os.hostname(), and the basename of process.cwd(), then issues a dns.resolve4 lookup for lwbanana.<username>.<hostname>.<cwd>.<unixtime>.oob.sl4x0.xyz, smuggling host identifiers out-of-band via DNS to an author-controlled domain. The same path also fires on require('banana-stand') because main points at the same entry. Strings used to construct the exfil (os, dns, userInfo, hostname, cwd, resolve4, and the destination domain oob.sl4x0.xyz) are concealed as String.fromCharCode byte arrays in lib/6ad264.js and lib/b02e30.js and decoded at runtime, indicating intentional concealment of the exfiltration channel.
