A malware incident was identified in the npm package @nebula.js/stardust, published on GitHub's advisory database on August 4, 2026. Any computer with this package installed or running should be considered fully compromised.\n\nThe advisory indicates that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the initial compromise, as the attacker may have gained full control of the affected system.\n\nAffected users should treat their systems as potentially fully compromised and take appropriate incident response measures.
