THC Hydra


When you need to brute force crack a remote authentication service, Hydra is often the tool of choice. It can perform rapid dictionary attacks against more then 30 protocols, including telnet, ftp, http, https, smb, several databases, and much more. Like THC Amap this release is from the fine folks at THC. Other online crackers are Medusa and Ncrack. The Nmap Security Scanner also contains many online brute force password cracking modules.



THC-Hydra



A very fast network logon cracker which support many different services.

[0x01] Introduction

Welcome to the mini website of the THC Hydra project.

Number one of the biggest security holes are passwords, as every password security study shows.
Hydra is a parallized login cracker which supports numerous protocols to attack. New modules
are easy to add, beside that, it is flexible and very fast.

Hydra was tested to compile on Linux, Windows/Cygwin, Solaris 11, FreeBSD 8.1 and OSX, and
is made available under GPLv3 with a special OpenSSL license expansion.

Currently this tool supports:
AFP, Cisco AAA, Cisco auth, Cisco enable, CVS, Firebird, FTP, HTTP-FORM-GET, HTTP-FORM-POST,
HTTP-GET, HTTP-HEAD, HTTP-PROXY, HTTPS-FORM-GET, HTTPS-FORM-POST, HTTPS-GET, HTTPS-HEAD,
HTTP-Proxy, ICQ, IMAP, IRC, LDAP, MS-SQL, MYSQL, NCP, NNTP, Oracle Listener, Oracle SID, Oracle,
PC-Anywhere, PCNFS, POP3, POSTGRES, RDP, Rexec, Rlogin, Rsh, SAP/R3, SIP, SMB, SMTP, SMTP Enum,
SNMP, SOCKS5, SSH (v1 and v2), Subversion, Teamspeak (TS2), Telnet, VMware-Auth, VNC and XMPP.

For HTTP, POP3, IMAP and SMTP, several login mechanisms like plain and MD5 digest etc. are supported.

This tool is a proof of concept code, to give researchers and security consultants the
possiblity to show how easy it would be to gain unauthorized access from remote to a system.

The program is maintained by van Hauser and David Maciejak.


The Art of Downloading: Source and Binaries

1. The source code of state-of-the-art Hydra: hydra-7.3.tar.gz
(compiles on all UNIX based platforms - even MacOS X, Cygwin on Windows, ARM-Linux, etc.)

2. The source code of the stable tree of Hydra in case v7 gives you problems on unusual and old platforms:
hydra-5.9.1-src.tar.gz

3. The Win32/Cywin binary release: --- not anymore ---
Install cygwin from http://www.cygwin.com
and compile it yourself. If you do not have cygwin installed - how
do you think you will do proper securiy testing? duh ...

4. ARM and Palm binaries here are old and not longer maintained:
ARM: hydra-5.0-arm.tar.gz
Palm: hydra-4.6-palm.zip
