About this tag
Threat detection on WindowsForum.com covers a range of security monitoring and analysis topics relevant to Windows-heavy enterprises. Discussions include network telemetry as a common source of truth for detecting lateral movement and command-and-control traffic, as seen in Vectra AI's approach. Ransomware operations like DragonForce hiding C2 traffic inside Microsoft Teams relays highlight the need for behavior-based detection beyond brand trust. AI-assisted EDR evasion frameworks built with tools like Cursor and Claude show how attacker tradecraft is evolving. Agent behavior analytics for ChatGPT and Microsoft Copilot address insider-style threats from AI workflows. Cookie-controlled PHP webshells and hardening RDP with NLA and sticky keys detection are also covered. These threads emphasize practical, behavior-focused threat detection strategies for Windows environments.
