var contents, row;

function password()

{

contents='';

row=Math.max(0,index-9);

while(row<index)

contents += tl[row++] + '\r\n';

document.forms[0].elements[0].value = contents + tl[index].substring(0,text_pos) + "_";

if(text_pos++==str_length)

{

text_pos=0;

index++;

if(index!=tl.length)

{

str_length=tl[index].length;

setTimeout("password()",2000);

}

} else

setTimeout("password()",speed);

<h1>Level 1</h1>

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.

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?

var sc_project=2497325;

var sc_invisible=0;

var sc_partition=23;

var sc_security="66a93703";

var sc_remove_link=1;

</script>

</body>

</html>

Kalo dilihat sekilas membingungkan memang..:D

Tapi coba kita perhatikan script pada bagian dibawah ini.

{

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>

Kita dapati “a” didefinisikan sebagai variable dan bernilai “null”..

Kemudian ada kondisi jika (document.a.c.value == a) maka akan dijalankan atau membuka document.location.href="http://www.hackertest.net/"+document.a.c.value+".htm"

Sebelumnya sudah kita ketahui bahwa nilai dari variable a = null

Selain dari nilai itu maka akan ditampilkan pesan “Try again"..

Nah skrng kita coba masukkan password dengan “null” (tanpa tanda petik)..

Dan tada…kita masuk ke level2..

untuk level 2 akan kita bahas pada kesempatan berikutnya..:D

Are you tired of chasing the kids around or having to hang around them every time they're using a gadget or their personal computers? do you think they do fishy stuffs with their gadgets? get a micro-chip installed on all their devices and gain total remote control.

I've been married to a man for over 3years and it took me so long to realize that he was sleeping with my best friend that I confirmed my suspicions by contacting a hacker to hack into his phone and provide me with all the necessary and completely overwhelming evidence to confront him. His email is "onlinehacker4hire {@} gmail com". He can hack into almost anything, including credit reports, school databases, embedded systems, etc. He can hack into almost anything. And he's very nice to work with.onlinehacker4hire at gmail dot com
