Description

The npm package 'hemi-tunnel-actions' contains malicious code that compromises any computer on which it is installed or running. Installation of this package may lead to full system compromise, including unauthorized access to secrets and keys stored on the affected machine. Immediate removal of the package is recommended, but due to the extent of the compromise, complete remediation may require additional measures such as rotating all secrets from a separate, uncompromised system.

Impact

Systems with the 'hemi-tunnel-actions' package installed are at risk of full compromise. Attackers may gain complete control, leading to the exposure and potential misuse of sensitive information such as secrets and keys. This level of compromise undermines system integrity and confidentiality, requiring urgent security response.

Defensive guidance

Remove the 'hemi-tunnel-actions' package immediately from all affected systems. Rotate all secrets and keys from a secure, uncompromised environment to prevent unauthorized access. Due to the potential for extensive system compromise, consider conducting a full incident response and forensic analysis to identify and remediate any additional malicious artifacts.

Summary

The 'hemi-tunnel-actions' npm package has been identified as containing malicious code. According to sources including Amazon Inspector and the GitHub Security Advisory for malware, any system with this package installed should be considered fully compromised. The malicious code potentially grants an attacker full control over the affected system, risking exposure of all stored secrets and keys. Removal of the package alone may not suffice to eliminate the threat, as the attacker may have installed additional malicious components.
