About this tag
Hunting queries are search patterns or KQL (Kusto Query Language) statements used to proactively identify threats, vulnerabilities, and suspicious activity in Windows environments. On WindowsForum, discussions focus on crafting hunting queries for CVEs such as CVE-2025-53737 (Excel heap overflow) and CVE-2025-50160 (RRAS VPN heap overflow). These queries help detect exploitation attempts, unpatched systems, and indicators of compromise. Topics include building queries for Microsoft Defender, Azure Sentinel, and event logs, as well as integrating threat intelligence feeds. The tag covers practical techniques for threat hunting, incident response, and security monitoring in enterprise Windows networks.
