Australian teenager admits causing Twitter hacker attack

A 17-YEAR-OLD Australian schoolboy said he caused a massive hacker attack on Twitter which sent users to Japanese porn sites earlier this week.

Pearce Delphin, whose Twitter name is @zzap, admitted exposing a security flaw which was then pounced upon by hackers, affecting thousands of users and causing havoc on the microblogging site for about five hours.

Delphin, who lives with his parents in Melbourne, said he tweeted a piece of “mouseover” JavaScript code which brings up a pop-up window when the user hovers their cursor over the message.
