A malware-laden version of the npm package @kl-dolphin/jump was identified and published on GitHub's advisory database (GHSA-wfwr-cf4w-fpj5). The package grants full control of the affected system to an outside entity upon installation or execution.\n\nAccording to the advisory, any computer with this package installed or running should be considered fully compromised. All secrets, keys, and credentials stored on affected systems should be rotated immediately from a different, uncompromised computer.\n\nWhile removal of the package is recommended, the advisory notes that full system compromise may have occurred, meaning removal of the package alone may not eliminate all malicious software that was installed as a result of the initial compromise.\n\nThe package should be avoided entirely, and users should verify their systems for any signs of compromise or unauthorized access.
