MAL-2026-10289: Malicious code in backup5-updated (npm)
The npm package 'backup5-updated' contains malicious code that fully compromises any computer on which it is installed or running. The compromise is severe enough that all secrets and keys stored on the affected system should be rotated immediately from a different, trusted computer. Simply removing the package does not guarantee removal of all malicious software, as the attacker may have established persistent control over the system.
AI Analysis
Technical Summary
The 'backup5-updated' npm package is identified as malicious software that, when installed or executed, results in a full compromise of the host computer. This includes potential unauthorized access and control by an outside entity. Due to the severity of the compromise, all sensitive credentials on the affected machine must be considered exposed and rotated from a secure environment. Removal of the package alone is insufficient to ensure system integrity, as additional malicious components may remain.
Potential Impact
Full system compromise on any computer with the package installed or running. Exposure of all stored secrets and keys on the affected system. Potential persistent unauthorized access by attackers. The integrity and confidentiality of the affected system are severely impacted.
Mitigation Recommendations
Remove the 'backup5-updated' package immediately. Rotate all secrets and keys stored on the compromised computer from a different, secure machine. Because the system may remain compromised even after package removal, consider rebuilding or thoroughly cleaning the affected system to ensure all malicious components are eradicated.
