mmmm...u know something we dont know?
no
just try to search for the words
hacked (or
hack) and
Wizi via google.com and you'll find a few threads on other PHPBB boards hacked the "same way" with the same f*****g text "
Hacked by Wizi!" and some additional information about that in russian like "I hacked this site for the second time and now in only 20 minutes" and similar...
on
some polish board (also hacked, but it looks like if they had good back-ups) is a thread about that also... they said, that Wizi's IP was 62.231.12.14
But I guess this is more a speculation, than a fact..
From all these links and information I just can guess, that Mr. Wizi is a handicapped and simple person with a sick mind who did read somewhere about the PHPBB security exploit and who's now searching all over the web for PHPBB Boards with the affected version of PHPBB to "hack 'em"... But this is just my humble opinion - maybe Wizi is a very nice guy with an IQ reaching the sum of the stars in the sky and he's doing this to make this world a better place...
