Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
Review the detections and related infrastructure.
Detection signal
Suspicious. A limited set of engine detections is present (6%).
Threat context
Classification includes type trojan.
Relationship context
6 related indicators are shown across 2 relationship group(s). Additional relationship intelligence is available through API and data access.
Observation timeline
7 timestamped observations are arranged from 2007-03-01 to 2026-10-20. These are observation or metadata times, not execution order.
Why this verdict
Review the reported detections, analysis confidence and supporting context.
The VirusSign analysis is supported by the detection, confidence, classification and relationship signals available for this indicator.
Reported engine detection rate. A low rate alone does not establish that the indicator is benign.
2 relationship group(s) provide pivot and infrastructure context.
Classification context: type trojan.
Last seen today.
Signals reflect the intelligence returned in this report. Missing values mean not reported, not zero. Related indicators are investigation leads, not proof of shared malicious activity.
