Burp bruteforce very slow


Recommended Posts


I have follow step by step this documentation to make a bruteforce on a login page:


I use a 10,000 entries dictionary.

At first, brutefroce is very fast (4/5 request/second)

But as long as the bruteforce occurs, each request takes more and more time to reach the webserver...

I use 2 VirtualBox VM. My host is 8gb, 4gb is dedicated to a guest and 1gb to the other.

I would like to know it is normal ? Or is it attacker problem ? Webserver problem ? Host technical configuration problem ?

I use the free version

I think Digininja has it. The free version is throttled, I believe.

I have read bruteforce is slower than the pro version, but here it appears slower and slower as the bruteforce occurs..

Read up on your tools, intruder on the free one degrades more and more over time. You are seeing expected behaviour.

Build the attack your self. Its a lot of fun to learn this stuff.. you can use curl or libs for perl,  python and ruby...


Learn why a firewall might ip ban you...
