Verdict Safe
Is genyo-
None of the 65 antivirus engines that checked it flagged this Java add-on archive, and the sandbox runs showed only the Java runtime starting it, with no high-risk techniques.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
This Java add-on shows no signs of malicious activity; use it if it came from the official source of the software it extends, and keep your security software enabled.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the project's own website.
Keep your security software and system updates switched on.

Why we think so
0 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The sandbox runs show the Java runtime launching it and writing routine runtime files. No injection target and no network activity of its own were recorded. It has been seen from 12 sources over about two months.
None of the 65 antivirus engines that checked it flagged the file, and all 18 major antivirus engines returned clean results. The sandbox runs recorded only the Java runtime processes needed to run the archive, plus standard JVM bookkeeping files. The behaviour mappings are techniques common in legitimate software, and the two higher-risk labels were mapped without any matching artefact or targeted process. The only network contact was the analysis machine's own background traffic. With no brand impersonation, no hostile dropped file and moderate prevalence, nothing in the evidence points to harmful intent.
What We Detected
None of the 65 antivirus engines that checked it flagged this Java archive. All 18 major antivirus engines, including Kaspersky, ESET, Microsoft and BitDefender, reported it clean. It has been submitted from 12 sources since it first appeared on Aug 23, 2026.
Threat Behavior
In the sandbox runs, the archive was started by the Java runtime. It wrote only ordinary JVM performance and usage files. No process injection target, persistence, registry changes or network contact of its own were recorded; the single contact observed was the analysis machine's background traffic. Some behaviour labels appear by default on many clean programs and were not backed by any matching activity. We do not have a complete reputation check for contacted hosts.
What To Do Now
If you obtained this add-on from the developer or the official distribution channel of the software it extends, it can be used normally. Keep your antivirus enabled and download future updates from the same trusted source.
Where this verdict could be wrong1 caveat
- Java archives can fetch further code when it ran, and no complete host-reputation result is available for this file. However, the sandbox recorded no network contact of the sample's own.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
