package.json declares `inquirer` with a tarball URL pointing at registrynpmjs.to — a domain that typosquats the official npm registry (registry.npmjs.org). Running `npm install` fetches and installs whatever tarball is hosted at that attacker-controlled URL as a transitive dependency, delivering arbitrary code into the installer's node_modules on every install. The package otherwise mimics a legitimate Hyperliquid TypeScript SDK (README shape, `@nktkas/rews` dep, jsr.io/@std references), and `inquirer` (an interactive-prompt library) is not a normal runtime dependency for a trading SDK, indicating the entry exists as a delivery vector rather than a functional dependency. Judge assessment: This looks like a supply-chain trojan delivered through a typosquatted external tarball dependency: `package.json` pins `inquirer` to `https://registrynpmjs.to/inquirer-14.0.2.tgz`, which would bypass npm registry controls and fetch attacker-controlled code on install. The package otherwise presents as a legitimate Hyperliquid SDK, but the suspicious dependency is not a normal runtime need for a trading SDK and matches the attacker model described in MAL-2026-14042. The repeated `fetch("https://api.hyperliquid.xyz/exchange")` calls in `src/signing/mod.ts` and related build artifacts are consistent with a real SDK, but they do not explain the registry-bypassing install hook. Given the malicious delivery vector and the typosquat domain `registrynpmjs.to`, this should be treated as a compromise of a legitimate package rather than a false positive.
