Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
High-confidence evidence. Related indicators in this report: 4. Review the supporting evidence before taking action.
Detection signal
Suspicious. A limited set of engine detections is present (14%).
Confidence signal
VirusSign reports 84% confidence. Review this alongside engine detections and relationship evidence.
Threat context
Classification includes type backdoor and family mirai.
Relationship context
4 related indicators are shown across 3 relationship group(s).
Observation timeline
5 timestamped observations are arranged from 2013-02-24 to 2026-05-16. 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 backdoor, family mirai.
