Hunt Hypothesis

This hunt identifies potential compromise by Azure Sentinel assets matching known indicators of compromise associated with the AMOS malware family. Proactively hunting for these IOCs allows the SOC team to detect lateral movement or persistence mechanisms before the adversary can establish a foothold or execute their intended objectives within the environment.
