Description

The colder-cli npm package contains malicious code that compromises any computer on which it is installed or run. Installation of this package can lead to full system compromise, including unauthorized access to secrets and keys stored on the affected machine. Removal of the package does not guarantee elimination of all malicious software introduced. Immediate secret and key rotation from a separate, uncompromised device is strongly recommended.

Impact

Full system compromise on any computer with the colder-cli package installed or executed. Potential exposure and theft of all secrets and keys stored on the machine. Persistence of malicious code beyond package removal is possible, increasing risk of ongoing unauthorized access.

Defensive guidance

Remove the colder-cli package immediately from all affected systems. Rotate all secrets and keys that were stored or used on the compromised machines, performing this rotation from a separate, trusted device. Because full system compromise is possible, consider a full system reinstallation or forensic analysis to ensure removal of all malicious components. Monitor for any suspicious activity related to the compromise.

Summary

The colder-cli package on npm has been identified as containing malicious code that fully compromises affected systems. According to the source advisory, any computer with this package installed or running should be considered fully compromised. Attackers may gain complete control, potentially accessing all stored secrets and keys. The advisory warns that simply removing the package may not remove all malicious artifacts, indicating persistence mechanisms or additional payloads may be involved.
