MAL-2026-6683: Malicious code in nbmolviz-js (npm)

0
Critical
Published: 06/30/2026 (06/30/2026, 15:13:14 UTC)
Source: GCVE Database
Product: nbmolviz-js

Description

The nbmolviz-js npm package 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 considered exposed and must be rotated from a different, trusted machine. Simply removing the package does not guarantee removal of all malicious components, as the attacker may have established persistent control over the system.

Technical Analysis

The nbmolviz-js package distributed via npm is identified as containing malicious code that results in a full system compromise upon installation or execution. This malicious package can lead to unauthorized control over the affected computer, exposing all stored secrets and keys. Due to the nature of the compromise, remediation requires not only removal of the package but also rotation of all credentials from a separate secure environment. There is no indication of a patch or fix since this is a case of a malicious package rather than a software vulnerability. No CVSS score is assigned, and no known exploits in the wild are reported at this time.

Potential Impact

Any system with the nbmolviz-js package installed or running is considered fully compromised. Attackers may have gained complete control, leading to exposure of all stored secrets and keys. The compromise may persist even after removal of the package, indicating potential installation of additional malicious software or backdoors.

Mitigation Recommendations

Remove the nbmolviz-js package immediately from all affected systems. Rotate all secrets, keys, and credentials from a different, trusted computer to prevent further unauthorized access. Because the system may remain compromised even after package removal, consider rebuilding or thoroughly cleaning affected systems to ensure complete eradication of malicious components.
