A critical malware incident was identified in the npm package @flex-ng/error-component. According to the GitHub Advisory (GHSA-pw64-8rr7-9h66), 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 package installation, as the attacker may have gained full control of the system.\n\nThis represents a severe supply chain attack through a compromised npm package with potential for widespread impact across all systems that have installed or executed it.
