Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The file received no detections from 75 antivirus engines, including 16 major antivirus engines, and the completed sandbox did not issue a malware verdict. Three offensive-technique mappings warrant caution, but no malicious child or external-intelligence match corroborates them; the eight files it created remain unclassified.
One sandbox run mapped activity to T1055, T1543.002, and T1562.001, but it produced no malware verdict and observed no network contacts. None of eight inspected child hashes was identified as malicious, although every child remains unclassified rather than confirmed benign. Research intelligence returned no CIRCL, MalwareBazaar, or YARAify match. Because the host-reputation cross-check was not completed or saved, no complete network-reputation conclusion is available.
What We Detected
None of the 65 antivirus engines that checked it flagged the JAR. CIRCL, MalwareBazaar, and YARAify supplied no matching intelligence.
Threat Behavior
One completed sandbox run mapped activity to T1055, T1543.002, and T1562.001. These mappings can be associated with process injection, service modification, and security-control impairment, but the sandbox issued no malware verdict and recorded no contacted domains, IP addresses, or URLs. Eight child hashes were inspected without a malicious result, though all eight remain unclassified. A complete contacted-host reputation result is unavailable because that cross-check was not saved.
What To Do Now
Keep security software enabled and obtain the JAR from its official project or distribution channel. If its origin is uncertain, verify its hash or release signature against the publisher's release information before running it.
Where this verdict could be wrong3 caveats
- The runtime mapping includes T1055, T1543.002, and T1562.001, which can represent process injection, service modification, and impairment of defenses.
- All 8 files it created have unknown verdicts, so the absence of a known-malicious dropped file does not establish that those files are benign.
- The missing contacted-host reputation result means no saved host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/65 antivirus engines reported a malicious or suspicious detection.
- 16 major antivirus engines reported it clean and no major antivirus engines flagged it.
- No sandbox returned a malicious verdict.
- No dropped file is known to be malicious.
- YARAify, MalwareBazaar, and CIRCL returned no hits.
- Evidence from the test run mapped activity to T1055, T1543.002, and T1562.001.
- The missing contacted-host reputation result leaves host-reputation coverage incomplete.
- The sample was first submitted on Aug 21, 2026.

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.
