Hunt Hypothesis

This hunt targets the presence of known SnappyClient IOCs, which are frequently leveraged by threat actors to establish persistent access or execute malicious payloads within Azure environments. Proactively hunting for these indicators allows the SOC team to identify compromised assets early, mitigating the risk of lateral movement or data exfiltration before the adversary can fully establish a foothold.
