MAL-2026-6855: Malicious code in next-bignumber.js (npm)
The next-bignumber.js package version 1.0.0 on npm contains malicious code that compromises any computer on which it is installed or running. This compromise potentially grants full control to an outside entity, risking exposure of all secrets and keys stored on the affected system. Removal of the package alone does not guarantee elimination of all malicious software introduced. Immediate secret and key rotation from a separate, uncompromised system is strongly advised.
AI Analysis
Technical Summary
The next-bignumber.js npm package version 1.0.0 is identified as containing malicious code. Installation or execution of this package results in a full compromise of the host system, allowing an attacker to gain control. Due to the severity of the compromise, all sensitive credentials stored on the system should be considered exposed and must be rotated from a different, secure environment. Simply removing the package does not ensure complete remediation, as the attacker may have deployed additional persistent malicious components.
Potential Impact
Full system compromise on any computer with next-bignumber.js version 1.0.0 installed or running. All secrets and keys stored on the system are at risk of exposure. The attacker may maintain persistent access beyond the presence of the malicious package itself.
Mitigation Recommendations
Remove the next-bignumber.js package version 1.0.0 immediately. Rotate all secrets and keys from a separate, uncompromised system. Conduct a thorough investigation and remediation of the affected system, as removal of the package alone does not guarantee elimination of all malicious artifacts.
