Hunt Hypothesis

This detection rule identifies adversary activity involving the ValleyRAT remote access tool by monitoring for specific indicators of compromise such as malicious file hashes and network connections. Proactive hunting is essential in Azure Sentinel to rapidly detect early-stage infections and prevent potential data exfiltration or lateral movement before the threat escalates.
