A critical malware incident was identified in the npm package @sflyinc-knapsack/shutterfly-react. According to the GitHub Security Advisory (GHSA-55g7-853c-wpj5), any computer with 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, unaffected computer. While the malicious package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software that resulted from installation.\n\nThis represents a supply chain compromise of the npm ecosystem through a malicious package distribution.
