MAL-2026-6905: Malicious code in winston-prism (npm)
The npm package winston-prism version 1.0.1 contains malicious code that compromises any computer on which it is installed or running. The presence of this package indicates a full system compromise, and all secrets and keys stored on the affected system should be rotated immediately from a different, trusted machine. Removing the package alone may not eliminate all malicious software introduced by it.
AI Analysis
Technical Summary
The npm package winston-prism version 1.0.1 is identified as containing malicious code. Installation or execution of this package results in a full compromise of the affected computer, potentially allowing an attacker complete control. Due to the severity of the compromise, simply uninstalling the package does not guarantee removal of all malicious artifacts. Immediate secret and key rotation from a separate secure environment is advised to mitigate ongoing risk.
Potential Impact
Full system compromise on any computer running or having installed winston-prism version 1.0.1. All stored secrets and keys on the compromised system are at risk and should be considered exposed. The attacker may have persistent access beyond the presence of the malicious package itself.
Mitigation Recommendations
Remove the winston-prism package version 1.0.1 from all affected systems. Immediately rotate all secrets and keys stored on the compromised systems using a different, secure computer. Because the system may be fully compromised, consider rebuilding or thoroughly cleaning the affected machines to ensure removal of all malicious software.
