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.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
No engine flagged the file. Sandbox analysis showed only routine Java runtime activity and no malicious verdict. The file has been submitted 495 times by 453 sources over six months, indicating established benign distribution.
Zero detections from 65 engines including 11 tier-1 vendors, combined with a clean sandbox verdict and broad prevalence, strongly indicate the file is benign. The single low-severity heuristic on direct-IP contact is inconclusive without host-reputation data. No dropped malicious children or external-intel hits further support safety.
What We Detected
65 antivirus engines scanned the JAR; none returned a malicious or suspicious result. 11 tier-1 engines explicitly classified it clean. Sandbox execution recorded typical Java runtime behaviour (process creation, temporary file writes) but no malicious verdict.
Threat Behavior
Two MITRE techniques flagged as offensive (T1543.002, T1562.001) are consistent with Java agent loading and debug-environment checks; they appear in many legitimate applications. One external IP was contacted, but no domain or malicious-host correlation is available.
What To Do Now
The file can be executed with standard precautions. Keep endpoint protection enabled; no additional action is required based on current evidence.
Where this verdict could be wrong1 caveat
- contactedHosts=null — host-reputation cross-check incomplete; no complete contacted-host reputation result was available or malicious from cache.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero malicious detections across 65 engines
- Clean sandbox verdict
- Broad, long-term prevalence (common_old)
The evidence supports treating the file as safe; continue normal use while keeping security software 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
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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.
