Remove the '@tw-marionette/input' package immediately from all affected systems. Rotate all secrets and keys stored on the compromised machines from a separate, trusted device. Due to the potential full system compromise, further forensic analysis and remediation may be necessary to ensure complete removal of malicious software.
