Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
High-confidence evidence supports blocking or enrichment review for this indicator.
Detection signal
Malicious. A limited set of engine detections is present (25%).
Confidence signal
VirusSign reports 94% confidence. Review this alongside engine detections and relationship evidence.
Threat context
Classification includes type trojan and family loader.
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.
Classification context: type trojan, family loader.
