A malware incident was identified in the npm package fireblocks-netlink-v2-api-validator. According to the GitHub Security Advisory (GHSA-rq6c-4p5q-xrjw), any computer with this package installed or running should be considered fully compromised.
The 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, 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 the installation.
This is a critical supply chain incident affecting the npm ecosystem, with the potential for widespread impact on any systems that depend on this package.
