A critical malware incident has been identified in the npm package reseller-app. According to the GitHub Advisory (GHSA-x3qj-pjpv-x4c6), any computer that has this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised computer. 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 package installation, as the attacker may have gained full control of the system.\n\nThis represents a critical supply chain attack through a compromised npm package with potentially severe impact on all systems where it was deployed.
