Domain Fronting is a technique that is typically used for censorship evasion. It relies on popular Content Delivery Networks (CDNs) such as Amazon’s CloudFront to mask traffic origins. By changing the HTTP Host header, the CDN will happily route us to the correct server. Red Teams have been using this technique for hiding C2 traffic by using high reputation redirectors.
