Changelog 9.5

• http-form:
  • The help for http-form was wrong. the condition variable must always be
    the last parameter, not the third
  • Proxy support was not working correctly
• smb2: fix for updated libsmb2 which resulted in correct guessing attempts
  not being detected
• smtp: break early if the server does not allow authentication
• rdp: detect more return codes that say a user is disabled etc.

Installation

git clone https://github.com/vanhauser-thc/thc-hydra.git

./configure

make

make install

Use

PROTOCOL is the protocol you want to use for attacking, e.g. ftp, smtp, http-get or many others are available TARGET is the target you want to attack MODULE-OPTIONS are optional values which are special per PROTOCOL module

FIRST – select your target you have three options on how to specify the target you want to attack:

1. a single target on the command line: just put the IP or DNS address in
2. a network range on the command line: CIDR specification like “192.168.0.0/24”
3. a list of hosts in a text file: one line per entry (see below)

SECOND – select your protocol Try to avoid telnet, as it is unreliable to detect a correct or false login attempt. Use a port scanner to see which protocols are enabled on the target.

THIRD – check if the module has optional parameters hydra -U PROTOCOL e.g. hydra -U smtp

FOURTH – the destination port this is optional! if no port is supplied the default common port for the PROTOCOL is used. If you specify SSL to use (“-S” option), the SSL common port is used by default.

If you use “://” notation, you must use “[” “]” brackets if you want to supply IPv6 addresses or CIDR (“192.168.0.0/24”) notations to attack: hydra [some command line options] ftp://[192.168.0.0/24]/ hydra [some command line options] -6 smtps://[2001:db8::1]/NTLM

Note that everything hydra does is IPv4 only! If you want to attack IPv6 addresses, you must add the “-6” command line option. All attacks are then IPv6 only!

If you want to supply your targets via a text file, you can not use the :// notation but use the old style and just supply the protocol (and module options): hydra [some command line options] -M targets.txt ftp You can supply also port for each target entry by adding “:” after a target entry in the file, e.g.:

Note that if you want to attach IPv6 targets, you must supply the -6 option and must put IPv6 addresses in brackets in the file(!) like this:

foo.bar.com

target.com:21

[fe80::1%eth0]

[2001::1]

[2002::2]:8080

[2a01:24a:133:0:00:123:ff:1a]
