The very same Trojan that stole 8 million Swedish kronor (about $1.2 million) from the Nordea bank was also used for a major attack in Australia. So says the hacker who calls himself "Corpse", a developer of advanced Trojans. Computer Sweden's reporter met him for an anonymous chat.

With the aid of security expert Per Hellqvist of Symantec, Computer Sweden tracked down the Russian-speaking hacker. Using a pseudonym, our reporter claimed to be interested in buying his own Trojan, tailored for attacking a bank online. It soon became obvious that Corpse knows very well that his application is used for major online banking frauds.

The bank accounts broken into are selected at random: "It's like roulette," he says in broken English. "Some have a million dollars, some have one dollar. You never know who gets infected."

Computer Sweden (CS): The Trojan that some people call Haxdoor, is that yours? Does it have the same functionality?

Corpse: Yes, Haxdorf (there are so many varieties) is mine.
