THC-Hydra – The Fast and Flexible Network Login Hacking Tool

Check For Vulnerabilities with Acunetix

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.

THC-Hydra

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:

hydra-5.4-src.tar.gz

Compile and install (./configure; make; make install)

IF you want the windows version you can grab this Cygwin version:

hydra-5.4-win.zip

More info is available 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!

  15. Alex 23 May 2008 at 1:07 pm Permalink

    now i have another problem,
    i downloaded cygwin, wrote the command, but it doesn’t work!
    what can i do?

  16. Bogwitch 23 May 2008 at 6:13 pm Permalink

    You’ll need to give a little more information than that. Any error messages? What do you mean ‘it doesn’t work’?

  17. Alex 23 May 2008 at 9:01 pm Permalink

    ok, when i write the command, ” no such file or directory” or “Error: Coudn’t find hydra.exe ” appears.

  18. Bogwitch 23 May 2008 at 9:28 pm Permalink

    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?

  19. lafluaf 31 October 2008 at 2:39 pm Permalink

    You have to store the dll files which comes with the zip package in you x:/cygwin/bin folder and then start it with a dos console.

    it’s a downgrade of the dll used in general

    the link to download it does not work. Where can you get a copy of it?

  21. Darknet 4 December 2008 at 6:40 am Permalink

    Links updated because you’re too retarded to Google for thc-hydra or just go to the homepage..

    “coudn`t create signal pipe”. what`s this?

  26. dblackshell 4 March 2009 at 8:40 am Permalink

    @jeck: are you running the windows version, or are you running it with cygwin… if the second is the case read the following http://www.cygwin.com/ml/cygwin/2005-02/msg00286.html

    I’m confused as to how this program works. Does it enable you to get passwords that have been entered into remote computers?

  28. Casso 30 May 2009 at 3:04 pm Permalink

  29. Bogwitch 30 May 2009 at 5:33 pm Permalink

    @Cosso, if you can’t managee to download the program, you shouldn’t be using it!
