This transmits the installer's host identifier to attacker-controlled infrastructure under the cover of an 'image download.' The package metadata, README, and code disagree three ways: package.json declares scope `@cw-ui/asio-neon-themes` ('themes'), README claims 'Simple Text Utils' with capitalize/reverse/wordCount, and the actual shipped code is an image-fetcher beacon. The author field is the placeholder 'Your Name'. The fetch follows arbitrary 301/302 redirects and writes the response bytes to `downloaded-image.jpg` inside the package directory with no integrity check, enabling staged-payload delivery — the endpoint can return any bytes, and the redirect handler accepts any destination.\n\n## Source: ghsa-malware (68b3e84776090e3839851e3e7d6cd3ac1e42e6b55c5f9f222fd17e87612a20e5)\nAny computer that has this package installed or running should be considered fully compromised.
