Before opening or running
Open or run it only when its publisher and download source have been independently verified.
If you already opened or ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
No engine flagged the sample. Sandbox execution produced no malicious verdict and no malicious children were dropped. The file has been submitted by 905 sources over three years with no adverse signals.
All 74 engines returned clean results, including 17 tier-1 engines. The single sandbox run recorded process-injection and direct-IP techniques, but both heuristics explicitly state they do not prove malicious intent. Prevalence data shows the file is common and old, reducing the likelihood of a new threat. The only limitation is the missing host-reputation check for the three observed IPs.
What We Detected
74 antivirus engines scanned the 54 MB JAR; none returned a malicious or suspicious result. Sandbox execution captured MITRE techniques T1055 and T1562.001, yet the heuristics note these mappings are inconclusive without further proof of intent.
Threat Behavior
No malicious child files were created. Three external IPs were contacted, but contactedHosts data is unavailable so their reputation cannot be confirmed. The file has maintained a clean record across 960 submissions since April 2022.
What To Do Now
Keep endpoint protection enabled. If the file is from an untrusted source, re-download from the original mod author and verify its SHA-256 hash before use.
Where this verdict could be wrong1 caveat
- contactedHosts is null — no complete host-reputation cross-check available for the three observed IPs (185.125.190.26, 185.125.190.27, 185.125.188.54).
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines flagged the sample
- common_old prevalence with 905 unique sources
- no malicious sandbox verdict or dropped children
- contactedHosts data unavailable for three observed IPs
The file shows no malicious indicators; it can be considered safe for normal use while standard protections remain active.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
Evidence"C:\Program Files\Java\jre-1.8\bin\java.exe" -jar "C:\Users\<USER>\Desktop\download.jar"The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

What to do now
This file appears low risk based on the evidence available now.
Open or run it only when its publisher and download source have been independently verified.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
