Hunt Hypothesis

This hunt targets adversaries deploying unknown data exfiltration tools that establish covert, encrypted command-and-control communications to stealthily extract sensitive information from the network. Proactively hunting for these behaviors in Azure Sentinel is critical because the absence of known indicators requires a behavioral approach to identify and contain novel threats before they compromise critical assets.
