In addition, lib/cache.js runs `module.require('node-net-pool')` inside a swallowed try/catch at top level, so the third-party payload also loads when a consumer `require()`s the package, extending the code-execution surface beyond install time to any downstream import. The account owning the tarball URL is unrelated to the package publisher, so whoever controls that branch controls arbitrary code delivered to every installer.\n\n## Source: ghsa-malware (84ee181e9b6b445ce9e2243b203fc25121cd29ea4e4a6bf8561c05fd0f361f94)\nAny computer that has this package installed or running should be considered fully compromised.
