Hunt Hypothesis

This hunt targets adversaries deploying the datPcShare.exe component of a Chinese hacktool suite to establish persistent access and exfiltrate sensitive data within Azure environments. Proactively hunting for this specific artifact is critical because its legitimate appearance often masks low-severity, long-term reconnaissance activities that may evade standard alerting thresholds until significant compromise occurs.
