Description

The npm package bcryptjs-node-js has been identified as containing malicious code. Systems with this package installed or running should be considered fully compromised. Immediate action is required to rotate all secrets and keys from a separate, secure computer. Removal of the package is recommended, but it may not fully eliminate the malicious presence due to potential full system compromise.

Impact

Any computer with bcryptjs-node-js installed or running is considered fully compromised, risking exposure of all stored secrets and keys. Attackers may have gained full control over the system, leading to potential data theft, unauthorized access, and persistent malicious activity.

Defensive guidance

Remove the bcryptjs-node-js package immediately. Rotate all secrets, keys, and credentials from a separate, secure computer that is not compromised. Because full system compromise is possible, consider rebuilding or thoroughly cleaning the affected systems to ensure removal of all malicious components.

Summary

The bcryptjs-node-js package on npm was found to include malicious code that compromises the security of any system on which it is installed or executed. According to sources including Amazon Inspector and the GitHub Security Advisory for malware, the presence of this package indicates a full system compromise. The advisory strongly recommends rotating all secrets and keys from a different, uncompromised machine and removing the package. However, because the attacker may have gained full control, removing the package alone may not eradicate all malicious software introduced.
