Verdict Safe
Is Jenny-
None of the 64 antivirus engines that checked it flagged this Java mod installer, and its sandbox run showed only ordinary Java launcher activity with no high-risk behaviour.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
This installer shows no signs of malware; use it if you downloaded it from the mod's official source, 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.
No scanner can promise a file is 100% safe.

Why we think so
0 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Its sandbox run returned a clean result, showing only the Java runtime launching the archive. The file has been seen by about 130 different submitters over three months.
None of the 64 antivirus engines that checked it flagged the archive, and all 18 major antivirus engines that analysed it reported nothing. The combined sandbox summary returned clean and recorded no high-risk techniques. The observed processes are the Java runtime and a command shell launching the JAR. The file has moderate reach, at roughly 130 distinct submitters. No public malware database or rule matches were recorded.
What We Detected
None of the 64 antivirus engines that checked it flagged this Java archive. Every major antivirus engine that analysed it, including Kaspersky, ESET, Microsoft and BitDefender, reported it as undetected. No malware-database or rule matches were recorded.
Threat Behavior
The sandbox run returned a clean result. It showed the Java runtime launching the installer and writing routine Java usage and performance files. Those labels are common on clean software. No network connections by the sample were recorded, but a full host-reputation check is not available.
What To Do Now
Only download Minecraft mod installers from the mod's official page or a reputable mod repository. Keep your antivirus enabled while installing, and rescan if you obtained the file from an unofficial link.
Where this verdict could be wrong1 caveat
- Minecraft mod installers are a common lure for Java-based stealers, and the sandbox tags mention debug-environment and CPU-name checks; however, no engine detection, hostile behaviour in the test run or malicious network contact backs that concern.
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.
