box-sign-client@1.0.0

Summary

box-sign-client@1.0.0 is a dependency-confusion vehicle positioned against the internal Box namespace (@box/sign-client). Its package.json declares a preinstall script (node index.js) that reads os.hostname() and process.env.USER/USERNAME, embeds those values into a subdomain of the hardcoded host iv6mfybhp42k33ysmzi73de5w.canarytokens.com, and calls dns.resolve() to trigger a DNS lookup against that subdomain. On any npm install that resolves this public package instead of the intended internal one, the installing host's hostname and login user are transmitted via DNS to a third-party Canarytokens collector at install time, before any application code is run. The package advertises itself as a proof-of-concept for Box dependency confusion, but the beacon fires against any installer regardless of intent.
