THC-Hydra rocks, it’s pretty much the most up to date and currently developed password brute forcing tool around at the moment.
It supports a LOT of services and protocols too.
Number one of the biggest security holes are passwords, as every password security study shows. Hydra is a parallelized login cracker which supports numerous protocols to attack. New modules are easy to add, beside that, it is flexible and very fast.

There are already several login hacker tools available, however none does either support more than one protocol to attack or support parallelized connects.
Currently this tool supports:
TELNET, FTP, HTTP-GET, HTTP-HEAD, HTTPS-GET, HTTP-HEAD, HTTP-PROXY, LDAP2,
LADP3, SMB, SMBNT, MS-SQL, MYSQL, POSTGRES, REXEC, SOCKS5, VNC, POP3, IMAP,
NNTP, PCNFS, ICQ, SAP/R3, Cisco auth, Cisco enable, SMTP-AUTH, SSH2, SNMP,
CVS, Cisco AAA.
However the module engine for new services is very easy so it won’t take a long time until even more services are supported. Planned are: SSH v1, Oracle and more…
This tool is a proof of concept code, to give researchers and security consultants the possibility to show how easy it would be to gain unauthorized access from remote to a system.
There is a lot more information contained in the README file here.
You can download Hydra here:
Compile and install (./configure; make; make install)
IF you want the windows version you can grab this Cygwin version:

[...] Once again this is an oldskool tool but a lot of people are still seeking it, for learning purposes I presume as there are better alternatives now like thc-hydra. [...]
[...] While Medusa was designed to serve the same purpose as THC-Hydra, there are several significant differences. For a brief comparison you can see here. [...]
Ubuntu and Debian users have the pre-compiled packages here:

Hello,
i tried to download the hydra-5.3-win.zip on
the THC-Hydra homepage, and my anti virus programm detected
a virus, is this normal for the data??
pls help me!
It is very usual for hacking tools to be identified as malware. Considering hacking tools are developed by the hacking community, it would be wise to treat any tool you have acquired with a fair degree of suspicion. If you have the ability, tools and techniques to either examine the source code or monitor what the application is actually doing it would probably be best to avoid attempting to hack altogether until you can.
Additionally, running any hacking tools on your production/ main workstation is a Bad Idea.
ok, thx for your advise!
now i have another problem,
i downloaded cygwin, wrote the command, but it doesn’t work!
what can i do?
You’ll need to give a little more information than that. Any error messages? What do you mean ‘it doesn’t work’?
ok, when i write the command, ” no such file or directory” or “Error: Coudn’t find hydra.exe ” appears.
OK, which error do you get under which circumstances?
Are you running the command from the directory where you extracted the files?
Is your anti-virus blocking access to the files?
