@flipbit2-bb/test-auth-statenpm

On npm install, a postinstall script (phone-home.js) collects os.hostname(), os.userInfo().username, process.platform + os.release(), a timestamp, and a package label, then issues an HTTPS GET to https://webhook.site/a536b433-b440-43ec-8399-26059196216e. The package is published under @flipbit2-bb/test-auth-state but the bundled tarball, README, and the phone-home payload's v field all identify as @atlassiansox/[email protected] — a dependency-confusion targeting of Atlassian's internal scope, with version 99.99.99 chosen to win internal-vs-public resolution. Any installer who pulls this package — not just the intended target — leaks host identifiers to the author's webhook.site endpoint. The package has no other functionality.

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.
