The reasoning behind this verdict

Analyst conclusion

Our analysis indicates this file is a legitimate installer for the NS-RPC project. The detections are limited to less reliable engines and lack corroboration from major antivirus engines or malicious behavioral indicators.

Where this verdict could be wrong2 caveats
  • The 'one of our behaviour rules' rule flagged direct IP connections, which could be interpreted as suspicious behavior in a more restrictive environment.
  • The lack of a digital signature prevents verification of the publisher, leaving the file's integrity reliant on the source repository.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
