Hydra

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

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.

Currently this tool supports: TELNET, FTP, HTTP, HTTPS, HTTP-PROXY, SMB, SMBNT, MS-SQL, MYSQL, REXEC, RSH, RLOGIN, CVS, SNMP, SMTP-AUTH, SOCKS5, VNC, POP3, IMAP, NNTP, PCNFS, ICQ, SAP/R3, LDAP2, LDAP3, Postgres, Teamspeak, Cisco auth, Cisco enable, LDAP2, Cisco AAA (incorporated in telnet module).

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.

Comments:

To install on Fedora Core 6 including postgresql support you will need the postgresql-devel package. To enable ssh for hydra, you will need to install libssh version 0.11.

If, after compiling and installing hydra, the tool complains with one of the following messages:
hydra: error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory
hydra: error while loading shared libraries: libapr-0.so.0: cannot open shared object file: No such file or directory
hydra: error while loading shared libraries: libssh.so: cannot open shared object file: No such file or directory
hydra: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory

Then you will need to create symbolic links to the libraries mentioned in the /usr/lib directory.

if you get the following error building XHydra:

/usr/include/bits/fcntl2.h:51: error: call to "__open_missing_mode" declared with attribute error: open with O_CREAT in second argument needs 3 arguments

You will need to change the following line in hydra-gtk/src/callbacks.c:
fd = open(filename, O_CREAT | O_TRUNC | O_WRONLY);
into:
fd = open(filename, O_CREAT | O_TRUNC | O_WRONLY, 0666);

On Slackware, you will receive an error:

Install the apache portable runtime (apr and apr-util) version 0.9, subversion and postgresql from source. Since apr installs by default in the /usr/local/apr directory, you will need to adjust the Makefile with the following directories:
XLIBPATHS=/usr/local/apr/lib
XIPATHS=/usr/local/apr/include/apr-1

I received the following error during make on Ubuntu:

or
error: expected "=", ",", ";", "asm" or "__attribute__" before "apr_off_t"

This is due to the fact that not all options are passed to the compiler. Change the first line in the Makefile file to:

CC=gcc `/usr/local/bin/apr-1-config -cppflags -cflags`

During compilation you might get the following error:

Add the following to the XLIBS variable in the Makefile:
XLIBS= -ldl -lssl -lcrypto
