Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The combined sandbox verdict across four runs was clean, with no network contacts and no high-risk techniques recorded. No reference database lists it as malware.
None of the 64 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that reported on it. The archive has been submitted by 206 distinct sources over roughly nine months, which is unusual for a targeted threat. Four sandbox runs produced a combined clean verdict, contacted no hosts, and showed only Java activity in the test run with no injection or persistence. One defence-tampering mapping appeared without any matching artefact, which is common on harmless files. Public malware-sharing and rule databases returned no matches. The archive's contents were not examined by our own static analysis, and no host-reputation check was saved.
What We Detected
None of the 64 antivirus engines that checked it flagged this Java archive, and no malware-sharing database or community rule set lists it. It has been submitted by 206 distinct sources since it was first seen on Jan 9, 2026.
Threat Behavior
Four sandbox runs launched the archive with Java on Windows and Linux. The combined sandbox verdict was clean: the runs recorded only ordinary Java runtime files, no network contacts, no injection into other processes, and no persistence. A defence-related technique label appeared without any supporting artefact, which is routine for harmless software. Our own static analysis did not examine the archive's contents.
What To Do Now
The evidence does not point to malware. If this is a game client or mod, obtain it from its official project page and keep your antivirus enabled while using it.
Where this verdict could be wrong2 caveats
- The file name suggests a Minecraft-style client or cheat loader, and the contents of the archive were not inspected by our own static analysis, so bundled unwanted code cannot be fully ruled out.
- Fresh or obfuscated Java malware is sometimes missed by engines that only see compressed class files, though wide distribution over many months makes that less likely here.
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 64 antivirus engines that checked it flagged the file.
