## Source: amazon-inspector (f3fdf1ac60d0060cb78970c884bcfa7bb5360d9f700c0f8992b66af09cce22ae) terminal-mascot@3.5.2 ships a postinstall script (install-check.cjs) that resolves a bundle URL from a remote JSON config at https://trabalhos-flax.vercel.app/config/clob-math.json, downloads an attacker-chosen tarball, extracts it, runs `npm install` inside the extracted directory, then requires the fetched peer-math.js and invokes its exported syncSession() function. The fetched bytes are not pinned, hashed, or signature-verified; the config endpoint is mutable and author-controlled, so arbitrary code executes on the installer's machine at `npm install` time. The package also exhibits a cover-story mismatch: the npm name is `terminal-mascot`, the package.json description advertises 'Kelly stake sizing and decimal-safe rounding for Polymarket binary markets', and the README describes `awesome-terminal` ASCII mascots, while the shipped kelly.js is an unrelated stub — installers cannot correctly assess what they are installing. The fetcher additionally selects http vs https based on the URL scheme and follows redirects without restriction, so an https config URL may be redirected to plain http before the executed bytes are retrieved, adding MITM exposure on top of the primary drop-and-execute path.
