Observation timeline
15 timestamped observations are arranged from 2014-11-11 to 2024-09-18. These are observation or metadata times, not execution order.
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.
5 relationship group(s) provide pivot and infrastructure context.
Classification context: type trojan, family msil.
