Summary
Malicious code in @su-doughnym/loginui (npm)
Details
Package self-identifies as a HubSpot dependency-confusion proof-of-concept and is published at version 99.99.99 — a typical high-version-pin used to win resolution against internal packages of the same name. On install, postinstall.js reads os.hostname(), os.userInfo().username, process.version, PID, and the package name/version, then prints them to stdout. There is no network I/O, no remote fetch, no eval, no filesystem writes outside normal npm behavior, and no credential access. An installer who unintentionally pulls this via a misconfigured registry/scope gets noisy install logs but no data exfiltration or code execution by an attacker. Routing to review because the package is a name-squat against an internal scope and the PoC nature plus the 99.99.99 version pin means future republishes by the same author could swap in real installer-harm behavior.

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.
