Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
Review the detections and related infrastructure.
Detection signal
Suspicious. A limited set of engine detections is present (5%).
Confidence signal
VirusSign confidence is elevated at 58%. Use it as supporting evidence together with detections, family and relationship context.
Threat context
Classification includes type trojan and family java.
Why this verdict
Review the reported detections, analysis confidence and supporting context.
The VirusSign analysis is supported by the detection, confidence, classification and relationship signals available for this indicator.
Reported engine detection rate. A low rate alone does not establish that the indicator is benign.
VirusSign analysis confidence; separate from detection rate and actor-association confidence.
Classification context: type trojan, family java.
Last seen 8 days ago.
Signals reflect the intelligence returned in this report. Missing values mean not reported, not zero. Related indicators are investigation leads, not proof of shared malicious activity.
