Why we think so
3 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 71 antivirus engines that checked it flagged this file, including all 17 major antivirus engines that returned results. It has been seen by more than 2,600 independent submitters since late 2022. The sandbox run ended clean, and its network activity was a GitHub update check. Two community YARA rules matched, but nothing else supports them.
Zero detections across 75 engines, with every major antivirus engine silent, is a strong clean signal for a file this widely distributed and this old. The sandbox run returned clean, and its only notable network call was a request to the project's own GitHub release feed. None of the 38 contacted hosts we inspected are known malicious or suspicious. Two community YARA rules, including one for the Jupyter infostealer, matched with no engine agreement, so we read them as pattern overlap. The missing code signature is a minor weakness for a hobbyist open-source tool.
What We Detected
None of the 71 antivirus engines that checked it flagged this file. It has circulated among more than 2,600 submitters since December 2022. Four community YARA rules matched: two generic ones, plus a Discord-domain rule and a Jupyter infostealer rule. No engine or malware database corroborates any of them. The file is not code-signed.
Threat Behavior
In one sandbox run the program loaded the .NET runtime and opened a browser link to install .NET 6. It also queried GitHub for the latest FrostyFix release, which is normal update-check behaviour. The run ended with a clean result. An injection mapping named a Windows WMI helper and Google updater processes, which looks like background system activity. No persistence was recorded.
What To Do Now
The file appears to be the FrostyFix game-modding helper. Download it only from the project's official GitHub page, and keep your antivirus enabled.
Where this verdict could be wrong3 caveats
- Two malware-specific community YARA rules matched, including one written for the Jupyter/Solarmarker infostealer, though no antivirus engine agrees.
- The sandbox mapped process injection into a Windows WMI helper, though the targets look like the analysis machine's own background activity.
- The file is unsigned, so no publisher identity backs it.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 71 antivirus engines that checked it flagged the file.
- More than 2,600 independent submitters have seen it over nearly four years.
- The sandbox run ended clean, and the app contacted its own GitHub release page to check for updates.
- None of the 38 contacted hosts we inspected are known malicious or suspicious.
- The file has no code-signing certificate.
- Two community YARA rules matched, including one aimed at an infostealer family.
- The sandbox mapped a process-injection technique, though the targets look like system background activity.
