Cloudflared

This brief detects network connection events associated with the Cloudflared tool, used to create tunnels via Cloudflare, potentially for unauthorized access or exfiltration, by establishing outbound connections to Cloudflare Edge Servers.

Attackers are increasingly abusing Cloudflare tunnels, created via the cloudflared client, for establishing stealthy command and control channels and evading network defenses by proxying traffic through Cloudflare's infrastructure.
