Brute-forcing with THC-Hydra


Haven't seen a tutorial about any online brute-forcing methods, so I decided to make one. We gonna use the UNIX distribution of THC-Hydra and I'll go through some of its main features and different attack methods.

First you’ll need Backtrack, of course. You can either run it in virtualization on a virtual machine like VMware or Virtualbox.
I will not cover how to boot Backtrack, there have already been lots of tutorials on the previous post.

1:Open up a terminal and type:



2:Once downloaded extract it!
   tar -xvf hydra-6.3-src.tar.gz



3:Now configuring and installing
   ./configure && make && install


4:Type "make install"






                                        HOW TO USE


If you are attacking FTP service then first make sure to run an nmap scan for any open FTP ports (by default it should be 21)

1:Type this command



2:The -l switch defines the username and the capital -L - a list of usernames for the brute-force  attack (if you don't know the login).
 The -p switch defines the password and the capital -P - the directory for the wordlists ( the -P is  used almost always)
 If we're attacking a web form over http and the method is post then we use "http-post-form" if the  service is FTP simply use "ftp".

3:use custom passd file
./hydra -L /root/usernames.txt -P /root/HugeDB.txt -e ns -vV -s 80 site.com http-post-form
"/login.php&username=^USER^&password=^PASS^
