Description

The npm package 'hemi-viem-stake-actions' was found to contain malicious code. Any system with this package installed or running should be considered fully compromised. It is recommended to remove the package and immediately rotate all secrets and keys from a different, trusted computer. Due to the potential full control gained by an attacker, removing the package alone may not eliminate all malicious software installed as a result.

Impact

Systems with the 'hemi-viem-stake-actions' package installed are considered fully compromised, potentially allowing attackers full control over the affected computer. All secrets and keys stored on the compromised system are at risk and must be rotated immediately. The malicious code may have installed additional malware, making simple removal insufficient to restore system integrity.

Defensive guidance

Remove the 'hemi-viem-stake-actions' package immediately. Rotate all secrets and keys stored on the compromised system from a different, secure computer. Due to the likelihood of full system compromise, consider rebuilding the affected system from a known good state to ensure complete removal of malicious software.

Summary

The 'hemi-viem-stake-actions' npm package contains malicious code that compromises the security of any computer on which it is installed or executed. The compromise is severe enough that all stored secrets and keys on the affected system should be rotated from a separate, secure environment. The presence of this package indicates a full system compromise, and removal of the package does not guarantee complete remediation due to possible persistence mechanisms.
