package.json for @polymarkets/clob-client-v2 declares its inquirer dependency as an HTTPS tarball URL on registrynpmjs.to, a lookalike of the real npm registry (registry.npmjs.org): "inquirer": "https://registrynpmjs.to/inquirer-14.0.2.tgz". On npm install, npm fetches and installs whatever tarball that host serves as inquirer into node_modules, so the operator of registrynpmjs.to controls the code that runs via inquirer's install lifecycle and on first require. The package is also published under the scope @polymarkets, a one-character variation of the legitimate Polymarket scope @polymarket, consistent with a typosquat lure whose delivery vector is the redirected dependency.
