Verdict Safe
Is 1trouser-
No antivirus engine detected the established JAR, while one sandbox exposed limited behavioral concerns that lack malicious host, child, or research corroboration.

Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 52 antivirus engines that checked it flagged this JAR, including the reporting major antivirus engines, and it has circulated through 362 sources over 231 days.
The strongest evidence is broad antivirus silence: 0 of the 52 antivirus engines that checked it reported a malicious or suspicious result. The file is also established rather than with 411 submissions from 362 sources over 231 days. One completed sandbox run did not issue a malicious verdict, and none of six inspected files it created was identified as malicious. However, the run mapped activity to and contacted 162.159.36.2 directly. Because no complete host-reputation cross-check was saved and the children retain unknown individual verdicts, those limitations warrant routine source verification despite the otherwise reassuring evidence.
What We Detected
None of the 52 antivirus engines that checked it flagged the JAR as malicious or suspicious. The sample has also been submitted 411 times by 362 sources over 231 days, indicating established circulation.
Threat Behavior
One completed sandbox run produced no malicious sandbox verdict. It nevertheless mapped activity to T1543.002 and T1562.001 and observed direct contact with 162.159.36.2. No complete saved host-reputation result is available for that IP. Six dropped files were inspected without a malicious-child finding, although their individual verdicts remain unknown.
What To Do Now
Obtain the JAR from its official project or distribution page and verify its SHA-256 value before running it. Keep security software enabled and use an isolated game or Java profile if the source cannot be independently confirmed.
Where this verdict could be wrong3 caveats
- The sandbox's offensive-technique list contains and T1562.001, techniques associated with service manipulation and impairment of defenses.
- One of our behaviour rules fired for 162.159.36.2, and the missing contacted-host reputation result leaves that IP without a complete saved reputation cross-check.
- All six inspected files it created have unknown individual verdicts, despite the absence of a known-malicious dropped file.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/52 antivirus engines reported a malicious or suspicious result.
- No major antivirus engines flagged it and 11 major antivirus engines reported it clean.
- Established prevalence: 362 sources and 411 submissions over 231 days.
- No sandbox returned a malicious verdict.
- No malicious file it created or external-intelligence hit was identified.
- Sandbox activity included offensive-class techniques and T1562.001.
- No contacted-host reputation result was saved, so complete reputation coverage for the observed IP is unavailable.
- Six files it created retain unknown individual verdicts.
