A DNS-over-HTTPS Command & Control Proof of Concept



  

  






## introduction

`godoh` is a proof of concept Command and Control framework, written in Golang, that uses DNS-over-HTTPS as a transport medium. Currently supported providers include Google, Cloudflare but also contains the ability to use traditional DNS.

## installation

All you would need are the `godoh` binaries themselves. Binaries are available for download from the [releases](https://github.com/sensepost/goDoH/releases) page as part of tagged releases.

To build `godoh` from source, follow the following steps:

* Ensure you have Go 1.13+

* Clone this repository with `git clone https://github.com/sensepost/goDoH.git`

* Run `make key` to generate a unique encryption key to use for communication

* Build the project with one of the following options:

  * `go build` which will drop you a new `godoh` binary for the current architecture

  * `make` which will drop binaries in the `build/` directory for various platforms
