Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
Elevated engine detections. Related indicators in this report: 11. Review the supporting evidence before taking action.
Detection signal
Malicious. Engine detections are elevated at 43%.
Confidence signal
VirusSign reports 100% confidence. Review this alongside engine detections and relationship evidence.
Actor context
Possible actor context is present for unc5174, but confidence is low.
Threat context
Classification includes type trojan and family downloader.
Relationship context
11 related indicators are shown across 3 relationship group(s). Additional relationship intelligence is available through API and data access.
Why this verdict
Review the reported detections, analysis confidence and supporting context.
Engine detections are elevated in this report. Review the reported confidence, classification and relationships alongside them.
Reported engine detection rate, not the probability that this indicator is malicious.
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 downloader.
Low confidence. Possible association for investigation.
