Malicious code in getui-library (npm)

On npm install, postinstall.js issues an HTTPS GET to https://webhook.site/18dc4281-d366-438a-9186-76fbcd56ade5 with query parameters containing the installer's hostname (os.hostname()), username (os.userInfo()), platform (os.platform()), current working directory, CI environment indicators, package name/version, and a timestamp. Errors are silently swallowed to avoid breaking the install. The package's own description self-identifies as a typosquat placeholder for the @getd/* scoped namespace, so any developer who mistypes the intended package name is fingerprinted without consent. Regardless of the author's stated 'defensive security research' rationale, the technical behavior is unconsented installer-side identifier exfiltration to a third-party webhook collector triggered automatically by the postinstall lifecycle hook.

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.
