Anonymize Traffic with Tor
Last modified: 2023-09-15
We can anonymize our traffic using Tor proxy and proxychains.
Anonymization
1. Configure Proxychains
First off, find the location of the proxychains configuration file.
find / -type f -name "*proxychains*" 2>/dev/null
Assume we found /etc/proxychains.conf then modify this file.
vim /etc/proxychains
We need to remove # in front of dynamic_chains, then comment out the strict_chain line and the random_chain line.
In addition, check the proxy_dns is uncommented for avoiding our DNS to be leaked.
...
dynamic_chain
...
# strict_chain
...
# random_chain
...
proxy_dns
Add socks4 127.0.0.1 9050 and socks5 127.0.0.1 9050 in the ProxyList section.
[ProxyList]
socks4 127.0.0.1 9050
socks5 127.0.0.1 9050
2. Start Tor Service
Before using proxychains, we need to start Tor service.
systemctl start tor
# Check the status
systemctl status tor
3. Use Proxychains
Now we can execute arbitrary command with proxychains. Our traffic should be anonymous thanks to Tor.
# Open Firefox browser.
proxychains firefox dnsleaktest.com
proxychains nmap x.x.x.x
- Check Public IP
To check our public ip address from command line, run the following command.
proxychains curl ifcfg.me
- Proxhchains Bash
If we don't want to append proxychains command every time, proxychains bash command eliminates the need to do that.
proxychains bash
# Confirm our public ip
curl ifcfg.me
4. Use Burp Suite
To use Burp Suite over Tor proxy, setup the SOCKS proxy in Burp Suite as below.
-
Open Burp Suite. We need to normally start Burp Suite without
proxychainscommand. -
Go to Proxy tab and click Proxy settings. Settings window opens.
-
In Settings window, go to User tab at the left pane, and click Network → Connections.
-
In SOCKS proxy section, click the switch "Override options for this project only", and fill the following forms:
SOCKS proxy host: 127.0.0.1 SOCKS proxy port: 9050 -
After that, check "Use SOCKS proxy".
-
Close the Settings window.
After setting up, we can use Burp Suite built-in browser over Tor proxy.
5. Stop Tor Service
After using proxychains and Tor, stop the Tor service.
systemctl stop tor
