What this malware does

The package's preinstall lifecycle script in package.json runs unconditionally on npm install and issues an HTTPS GET to https://jnhwbzedabyratvgvgpgo7wtsmhsiw8d4.oast.fun/?host=shopify-<hostname>, where <hostname> is taken from os.hostname(). The oast.fun domain is a public out-of-band interaction service (interactsh) commonly used as a callback collector, so this beacon discloses the installer's machine hostname to a remote third party at install time. The package name shopify-app-bridge-internal (unscoped) with version 99.9.9 and an internal suffix is the canonical dependency-confusion shape against Shopify's official scoped @shopify/app-bridge, designed to be resolved by internal build systems that look up a private dep name against the public registry. Despite the package's self-description as a bug-bounty PoC, the install-time beacon harms any installer that resolves the name.
