Verdict Safe
Is m1mjnq51y.
No antivirus engine flagged this widely submitted JAR, while concerning sandbox technique mappings lack a malicious runtime verdict or independent threat corroboration.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
Proceed only when the JAR came from a trusted, expected source; otherwise verify its publisher and checksum before execution. Keep antivirus protection enabled and avoid unnecessary administrator privileges.

Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 66 antivirus engines that checked it flagged the file, including 17 major antivirus engines, and it has been submitted by 977 sources. One sandbox mapped several offensive techniques, but found no confirmed injection target, issued no malicious verdict, and contacted hosts with no cached threat matches.
The strongest evidence is the complete absence of detections among 75 engines, including no major alerts. The file also has broad recent prevalence, with 977 submitters and 1,181 submissions. However, those mappings came from one run, no injected process was identified, and the sandbox did not issue a malicious verdict. Host-reputation coverage included every distinct observed domain, IP address, and URL host and returned no malicious or suspicious matches. No malware-specific research rule, known malicious child, or named family independently corroborates the behavioral mappings.
What We Detected
None of the 66 antivirus engines that checked it flagged the JAR, and all 17 reporting major antivirus engines returned no detection. The file has also appeared across 977 sources and 1,181 submissions, indicating broad recent circulation rather than an isolated sample.
Threat Behavior
One sandbox run mapped T1003 credential dumping, T1055 process injection, T1543.002 service persistence, and T1562.001 security-control impairment. These mappings are concerning, but no injection target was recorded, no malicious sandbox verdict was produced, and the Java-related registry and process activity does not by itself establish hostile intent. The run contacted three distinct hosts; all were covered by the available reputation check, with no malicious or suspicious cache matches. Nine dropped files have no saved verdict and therefore remain unresolved rather than exonerated.
What To Do Now
Use the file only if it came from an expected source and its purpose is understood. Keep security software enabled, and avoid granting administrator privileges unless the application clearly requires them and the publisher can be verified.
Where this verdict could be wrong3 caveats
- The sandbox mapped credential access, process injection, service persistence, and security-control impairment techniques, although it did not identify an injection target or issue a malicious runtime verdict.
- The JAR contacted doomsday-themed domains and wrote a Java preferences key resembling a run-with-root setting; neither the hosts nor the activity received independent threat corroboration.
- Nine dropped files lack saved verdicts, so their nature remains unresolved despite no child being identified as malicious.
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 66 antivirus engines that checked it flagged the file, including all 17 reporting major antivirus engines.
- The file has broad recent prevalence across 977 submitters and 1,181 submissions.
- The reputation check covered all three observed hosts and found no cached malicious or suspicious matches.
- No malware-specific research rule, known malicious file it created, or named threat family corroborated the sandbox mappings.
- A sandbox mapped credential dumping, process injection, service persistence, and security-control impairment techniques.
- The file contacted doomsday-themed infrastructure and wrote a Java preferences entry resembling a persistence or elevated-run setting.
