Hacker Test - Level 1

Description:

Level 1

Hackers solve problems and build things, and they believe in freedom and voluntary mutual help. To be accepted as a hacker, you have to behave as though you have this kind of attitude yourself. And to behave as though you have the attitude, you have to really believe the attitude.

Solution:

1. View page source code and find the HTML of the above form.

   <div align="center">
   <center>
   <table border="1" cellspacing="1" style="border-collapse: collapse" bordercolor="#111111" width="15%" id="AutoNumber4">
   <tr>
   <td width="100%">
   <p align="center"><font size="1" face="Tahoma"><br>
   </font><font size="2" face="Tahoma">Password:</font><form name="a" action="javascript:check()">
   <p align="center">
   <input type="login" name="c" maxlength="25" size="16"><br>
   <br>
   <input type="submit" value=" Log In "></p>
   </form></p>
   </td>
   </tr>
   </center>
   

2. Now we knew that there's a JavaScript function named 'check()' would check our submitted password.
3. Let's check it.

   <script language=JavaScript>
   {
   var a="null";
   function check()
   {
   if (document.a.c.value == a)
   {
   document.location.href="http://www.hackertest.net/"+document.a.c.value+".htm";
   }
   else
   {
   alert ("Try again");
   }
   }
   }
   </script>
   

4. Yes, the password is "null" and the URL of level 2 is :
   http://www.hackertest.net/null.htm
