Aussie, Aussie, Aussie, oi, oi, oi. Australian schoolboy Pearce Delphin (17) was behind the ‘mouse worm” that wreaked havoc on Twitter. Woohoo.For 5 hours Twitter uses were sent to porn sites, had friggin pop-ups appear when they moved their mouse or had their twitter messages automatically retweeted. Even staff at the White House and Gordon Brown’s wife were affected (like we care). Moral of the story is don’t tweet a friggin code which causes a pop-up window to appear when you move your mouse over a tweet because every porn company and Russian hacker is going to use it for evil.
