A critical malware incident was identified in the npm package iwsdk. According to the GitHub Advisory (GHSA-35fw-734c-r8xf), any computer that has this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning there is no guarantee that removing the package will remove all malicious software resulting from the installation.\n\nThis represents a critical supply chain attack through a compromised npm package with potential for widespread impact across all systems where iwsdk was deployed.
