Zoom High Video Latency Detection

This rule detects unusually high video latency in Zoom sessions. Elevated latency, particularly above 300ms, can be an indicator of suspicious activity such as Remote Employment Fraud (REF), where threat actors might be operating from geographically distant locations or using compromised network infrastructure, leading to poor connection quality. The rule extracts and analyzes average and overall video latency from Zoom Quality of Service (QoS) logs for participants.
