The package '@mc-xp/mc-monolith-js-src-package' at version 99.9.1 on npm has been flagged as malicious by the OpenSSF Package Analysis project and the GHSA database. The malicious behavior includes communication with a domain associated with malicious activity, suggesting that systems with this package installed may be fully compromised. Immediate action is required to remove the package and rotate any secrets or keys that may have been exposed. Due to the potential full compromise, removing the package alone may not fully remediate the threat.

Any computer with this package installed or running should be considered fully compromised. Attackers may have gained full control, risking exposure of all secrets and keys stored on the system. This can lead to unauthorized access, data theft, and further malicious activity originating from the compromised host.

Remove the '@mc-xp/mc-monolith-js-src-package' version 99.9.1 from all affected systems immediately. Rotate all secrets and keys that were stored on the compromised systems from a separate, trusted environment. Because full system compromise is possible, consider rebuilding or thoroughly auditing affected systems to ensure no residual malicious software remains.
