Description

The npm package @calm2026/imux contains malicious code that fully compromises any computer on which it is installed or running. Removal of the package does not guarantee elimination of all malicious software introduced. Immediate rotation of all secrets and keys stored on the affected computer from a different, secure machine is strongly advised.

Impact

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.

Defensive guidance

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.

Summary

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.
