MAL-2026-10309: Malicious code in imillegal4 (npm)
The npm package 'imillegal4' 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 device. Removing the package alone does not guarantee removal of all malicious software introduced by it, as the attacker may have gained full control of the system.
AI Analysis
Technical Summary
The 'imillegal4' package in the npm ecosystem is identified as malicious software that, when installed or executed, results in a full system compromise. The advisory warns that any system with this package should be considered fully compromised, necessitating immediate rotation of all secrets and keys from a separate secure system. Due to the potential for persistent malicious presence beyond the package itself, removal of the package does not assure complete remediation.
Potential Impact
Full compromise of the affected computer, including potential unauthorized access and control by an attacker. All stored secrets and keys on the compromised system are at risk and must be rotated. The persistence of malicious software beyond the package installation means the system integrity and confidentiality are severely impacted.
Mitigation Recommendations
Remove the 'imillegal4' package immediately. Rotate all secrets and keys from a different, secure computer. Because the system may remain compromised even after package removal, consider rebuilding or thoroughly cleaning the affected system to ensure complete eradication of malicious software.
