Hackertest.net

Another site that I came across recently, with real serious hacking missions is hackertest.net. They have a series of 20 exotic mission to test your skills requiring knowledge of JavaScript, PHP, HTML and stuff like that. Here is what they say about themselves.

HackerTest.net is your own online hacker simulation. With 20 levels that require different skills to get to another step of the game, this new real-life imitation will help you advance your security knowledge. HackerTest.net will help you improve your JavaScript, PHP, HTML and graphic thinking in a fun way that will entertain any visitor! Have a spare minute? Log on! Each level will provide you with a new, harder clue to find a way to get to another level. Will you crack HackerTest.net?

Missions on this site are pretty good and need harder efforts as you move on to harder levels. Good luck!!!

HACKTHISSITE.ORG | Javascript Mission 7: JS Obfuscation. FTW!

Now this one is a little tricky if you are not experienced with programming. After all the earlier missions, you tend to look for the same code that you saw earlier and get obfuscated. But this one too is very simple.

Like earlier levels you will not find the exact source code in this one. The button tag you were looking earlier missions, is not present in this source code. Well guys, the button is just there, its just that you cannot see it.

HACKTHISSITE.ORG | Javascript Mission 6: go go away .js

This mission is also as simple as the earlier were. When you will open the source code you will find two functions there namely check and checkpassw.

RawrRawr = "moo";
function check(x)
{
    "+RawrRawr+" == "hack_this_site"
    if (x == ""+RawrRawr+"")
    {
        alert("Rawr! win!");
        window.location = "about:blank";
    } else {
        alert("Rawr, nope, try again!");
    }
}

function checkpassw(moo)
{
   RawrRawr = moo;
   checkpass(RawrRawr);
}

But when you will further check out the source code, you will see that the function you are calling from button tag this time is different, than the one’s given above. It is now checkpass.

HACKTHISSITE.ORG | Javascript Mission 5: Escape!

Unescape and escape are javascript functions used to encode and decode string just to make sure they are unreadable easily, but still its not that difficult to read them.

When you check out the source code you will find that there is an encoded string ‘%69%6C%6F%76%65%6D%6F%6F‘ and the variable moo has its decoded word i.e. our answer.
