Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The single generic detection is isolated to a less reliable engine, while none of the 66 antivirus engines that checked it includes a detection from a major antivirus engine. A completed sandbox run returned clean, and the exact hash appears as an official GitHub release asset, making the McAfeeD label highly likely to be a false positive.
McAfeeD produced the only detection among 75 engines, using the generic label GenericY; no major antivirus engines agreed. The completed sandbox run returned clean, although it mapped and T1562.001. Those mappings are not conclusive because no injected target process was recorded and no persistence or network activity was observed. Independent intelligence supplied no malware-family rules or repository match, and GitHub lists the exact hash as a release asset for aurickk/OpSec. A complete contacted-host reputation result is unavailable, so the assessment does not rely on a claim of clean network reputation.
What We Detected
McAfeeD was the only engine to flag the file, assigning the generic label Trojan:Win/GenericY.JTJ. None of the 17 reporting major antivirus engines flagged it, and no named-family consensus emerged. The exact SHA-256 is also listed for the matching filename in the aurickk/OpSec V1.1.7.1 GitHub release.
Threat Behavior
One completed sandbox run returned clean. It mapped T1055 and T1562.001, but no injected process target was recorded, no persistence indicator was created, and no sample network contacts were observed during that run. Host-reputation coverage was not available, so no broader network-reputation conclusion is made. Five dropped files lack saved verdicts and are therefore neutral rather than evidence of harm.
What To Do Now
Keep security software enabled and obtain the JAR from the project release page rather than an unrelated mirror. Verify that its SHA-256 is 999da53ce2c33e3a9690a63add35c13067b9b2a8a575a08e77209954e1d5fcae before running it, and use only the expected Java environment.
Where this verdict could be wrong3 caveats
- The sandbox mapped process injection and impairment of defenses, but it identified no injected process and returned a clean run.
- Several community annotations call the sample njRAT or malware, but these unsupported labels conflict with the engine results, sandbox outcome, and exact release-asset hash.
- The contacted-host reputation cross-check was not available, so no complete host-reputation conclusion can be drawn.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 17 reporting major antivirus engines flagged the file.
- The only detection came from one less reliable engine and used a generic family label.
- The completed sandbox run returned clean and recorded no persistence or sample network contacts.
- The exact filename and SHA-256 are published as an aurickk/OpSec V1.1.7.1 GitHub release asset.
- No malware-specific YARA rules or malware-repository record corroborated the detection.
- The sandbox mapped possible process injection and defense-impairment techniques, though it did not record an injection target.
- One engine applied a generic trojan label.
- The complete reputation of any potential contacted hosts was not checked.

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.
