Geopolitical Cyber-Detection Lures for Attribution with Microsoft Sentinel 

This blog post demonstrates how to use Microsoft Sentinel with Log Analytics to rapidly profile brute-force activity against internet-exposed RDP and SSH services by querying Windows EIDs 4624/4625 and Syslog 'Failed password' messages via shared KQL; it shows attacks ramp up within an hour, often sourcing RDP attempts from Russian IP ranges and SSH from Southeast Asia, and recommends building geo-heatmaps and using the findings to guide network blocking.
