Hunt Hypothesis

This hunt identifies potential compromise by matching network traffic and asset data against 24 known indicators of compromise associated with the AMOS malware family. Proactively hunting for these IOCs in Azure Sentinel allows the SOC to detect stealthy lateral movement or command-and-control channels before the adversary establishes a persistent foothold in the environment.
