Proxying BurpSuite through TOR

Hi everyone, Today i am going to demonstrate how to send BurpSuite requests through tor proxy servers. First understand the scenario what we are going to do,

In general we set our browser’s proxy to “127.0.0.1:9050” on which tor proxy daemon is running. So our request is directly going through “tor proxy servers” to the destination.

Browser –> Tor Proxy –> Destination

Lets add BurpSuite in-between the Browser and a Tor proxy, to do so we need to specify two interfaces to Burp one will handle requests from the browser to Burp and second will send requests from Burp to tor proxy.

Step 1:- Install tor

Open /etc/apt/resouces.list file using any editor in BackTrack and add following line.

“deb http://deb.torproject.org/torproject.org lucid main”

Open command prompt and run following commands to install tor

gpg –keyserver keys.gnupg.net –recv 886DDD89

gpg –export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add –

apt-get update

apt-get install tor tor-goipdb

apt–get install privoxy

Now we have successfully installed tor & piroxy.

Step 2:- Configure

open /etc/privoxy/config file and uncomment the following line

forward-socks4a / 127.0.0.1:9050

start both the services tor & privoxy.

/etc/init.d/tor start

/etc/init.d/privoxy start

Step 3:-Set BurpSuite

First you need to configure your browser to point to Burp for outbound HTTP & HTTPS connection, then you need to set your SOCKS proxy to point to your tor service running on port 9050 by default.

Finally configure BurpSuite to point to privoxy.

Select “options tab” in Burp and navigate to ‘upstream proxy server’ click on ‘add’ button. By default privoxy runs on port ‘8118’ so add proxy host and port accordingly.
