Description

The npm package x402-prompt-injection-scan version 0.1.4 is identified as malicious software. Although static and behavioral scans did not detect typical malicious behaviors such as network communication or credential harvesting, the package is considered fully compromising to any system where it is installed or running. Immediate removal of the package and rotation of all secrets and keys from a different, uncompromised system is strongly advised.

Impact

Any computer with the x402-prompt-injection-scan@0.1.4 package installed or running should be considered fully compromised. This implies potential unauthorized control or access by an attacker. All secrets and keys stored on the affected system must be rotated immediately from a separate, secure system. Removing the package alone may not eliminate all malicious software introduced by its installation.

Defensive guidance

Remove the x402-prompt-injection-scan@0.1.4 package immediately from affected systems. Rotate all secrets and keys stored on the compromised computer using a different, uncompromised system. Since full control of the computer may have been given to an attacker, further forensic analysis and remediation may be necessary.

Summary

The npm package x402-prompt-injection-scan@0.1.4 has been flagged as malware. Static analysis and behavioral tracing found no direct evidence of malicious activity such as lifecycle execution, outbound network connections, credential harvesting, or persistence mechanisms. However, authoritative sources classify any system with this package installed or running as fully compromised, recommending urgent secret rotation and package removal. There is no indication of known exploits in the wild or a CVSS score.
