(Please note that I have no affiliation with the leak of this tool, nor do I endorse DoS attacks and I did not write the information below. All I did was to organize it nice and short, in a way very easy to read in short time.)
* Leaked - th3j35ter's XerXeS Attack Platform
* Uses TORHAMMER with Keep-Alive DDOS on hacked PHP servers
* Method of attack: HEAD keep/alive + range
What was it tested against?
Here is what I then did. I set up a HoneyPot (hardened Apache with DDOS protection turn on). The site was "http://www.rjfront.info". On 28 August, 2011. I logged onto IRC.2600.NET channel #jester and requested that the "ANTI-JIHAD" site would be taken down. With-in 45 minutes, the server was hit with HTTP HEAD partial fragmentation attacks. The server was completly down in 3 minutes for up to 5 hours.
How the attack looks like in the logs:
The Apache logs revealed the following headers:
220.127.116.11 - - [28/Aug/2011:14:05:34 +0330] "HEAD / HTTP/1.0" 200 4011 "-" "XerXes - 0wn3d bitch. TANGO DOWN"
18.104.22.168 - - [28/Aug/2011:14:07:39 +0330] "HEAD / HTTP/1.0" 200 4011 "-" "XerXes - 0wn3d bitch. TANGO DOWN"
22.214.171.124 - - [28/Aug/2011:14:10:50 +0330] "HEAD / HTTP/1.0" 200 4011 "-" "XerXes - 0wn3d bitch. TANGO DOWN"
Quote from the story behind:
What was interesting was the the sequence of IP's that were rotated. They were TOR exit relays. After doing a bit of research on the type of attack agaist te HoneyPot was an attacked called "Keep-Alive DoS Script": http://www.esrun.co.uk/blog/keep-alive-dos-script/. The CPU utilization on the Apache server was 95% throughout the attack.
