The @calm2026/imux npm package is identified as containing malicious code that compromises the host system completely. According to the source advisory, installation or execution of this package results in full system compromise, potentially allowing an attacker to control the affected computer. Due to the severity of the compromise, simply removing the package is insufficient to restore system integrity, as additional malicious software may persist. No CVSS score or detailed technical exploit information is provided. There is no indication of known exploits in the wild or available patches.

Any system with the @calm2026/imux package installed or running should be considered fully compromised. This includes potential unauthorized access and control over the system, leading to exposure or theft of all stored secrets and keys. The compromise may persist beyond removal of the package, indicating a high risk of persistent malicious presence.

Remove the @calm2026/imux package immediately. Rotate all secrets, keys, and credentials stored on the affected system from a separate, secure computer. Because full system compromise is indicated, consider rebuilding the affected system from a known good backup or reinstalling the operating system to ensure removal of all malicious components. Monitor for any suspicious activity and avoid using the compromised system until it is fully remediated.
