WebDAV Traffic to Cloudflare Tunneling Service
This rule detects HTTP traffic originating from a client within the home network to an external Cloudflare tunneling service (specifically, domains ending in '.trycloudflare.com') where the User-Agent header indicates 'Microsoft-WebDAV-MiniRedir'. This combination suggests potential command and control activity or data exfiltration using WebDAV over a Cloudflare tunnel, often employed by adversaries to bypass network restrictions and obscure their infrastructure.
