Classification includes type trojan and family vshell.
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 vshell.
Low confidence. Possible association for investigation.
