High-confidence evidence. Related indicators in this report: 8. Review the supporting evidence before taking action.
Detection signal
Malicious. A limited set of engine detections is present (21%).
Confidence signal
VirusSign reports 94% confidence. Review this alongside engine detections and relationship evidence.
Threat context
Classification includes type trojan and family gen4.
Relationship context
8 related indicators are shown across 3 relationship group(s).
Observation timeline
9 timestamped observations are arranged from 2014-08-19 to 2026-11-09. These are observation or metadata times, not execution order.
Why this verdict
Review the reported detections, analysis confidence and supporting context.
VirusSign reports high analysis confidence alongside a low or unreported engine detection rate. These are different measures; review the supporting classification and relationships.
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.
3 relationship group(s) provide pivot and infrastructure context.
Classification context: type trojan, family gen4.
