Esse foi um bug fixo na versão 8.2-pre, como o log de alterações descrito link
Estou apenas experimentando a hydra no OSX Yosemite, instalada com bebida
brew info hydra

para testar post de formulário em html, este é o caso.
Eu tenho o arquivo php sendo executado com o servidor da web apache chamado 'index.php' da seguinte forma:
<?php
$login = 'admin';
$password = 'r00t';
?>
<html>
<head>
<title>PHP Form Auth</title>
</head>
<body>
<?php
if (isset($_POST['go_field']))
{
if ($_POST['login_field'] == $login && $_POST['password_field'] == $password)
{
echo 'Logged in';
}
else
{
echo 'Error';
}
}
else
{
?>
<form method="POST">
<input type="text" name="login_field" /> Login <br />
<input type="password" name="password_field" /> Password <br />
<input type="submit" name="go_field" value="Login" />
</form>
<?php
}
?>
</body>
Ele está sendo executado na minha máquina, ou seja,
http://localhost/security/3/php/index.php
Basicamente, é um formulário html que imprime a string 'Logged in' se o login for bem-sucedido, caso contrário, imprimirá a string 'Error'.
Eu testei usando user: admin password: r00t no navegador, ele disse 'Logged in'. E eu uso credencial com falha, ele disse 'Erro'
No entanto, com a hydra, tentei:
hydra -l admin -p r00t localhost http-post-form "/security/3/php/index.php:login_field=^USER^&password_field=^PASS^&go_field=Login:Error"
Eu recebi esta saída:

Não sei bem onde estava errado. Alguém poderia me notar ou sugerir?
A seguir, cabeçalhos http quando uso o formulário http com o navegador:
POST /security/3/php/ HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:33.0) Gecko/20100101 Firefox/33.0

Depois que eu tentei construir esses cabeçalhos em hydra, eu emito:
hydra -v -V -l admin -p r00t -s 80 localhost http-post-form "/security/3/php/index.php:login_field=^USER^&password_field=^PASSWORD^&go_field=Login:Error:H=Host: localhost:H=User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:33.0) Gecko/20100101 Firefox/33.0:H=Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8:H=Accept-Language: en-US,en;q=0.5:H=Accept-Encoding: gzip, deflate:H=Referer: http://localhost/security/3/php/:H=Cookie: __vjstorage=%7B%7D:H=Connection: keep-alive:H=Content-Type: application/x-www-form-urlencoded:H=Content-Length: 52"
