Hunt Hypothesis

This hunt hypothesis targets adversaries leveraging DCRat malware to establish persistent command-and-control channels and execute remote management tasks within the network. Proactively hunting for these specific IOCs in Azure Sentinel is critical to rapidly identify early-stage compromises before attackers can expand their foothold or exfiltrate sensitive data.
