Hacker interrupts AVG's malware analysis

'Why are you researching my trojan?'

A hacker has sprung AVG malware researchers midway through their analysis of a trojan crafted to trap Diablo gamers.

The researchers had discovered the malware on the Taiwan battle.net games forum and picked it apart to seek-out keylogging capabilities that would explain the recent theft of gamer data from Diablo III fans.

But during the analysis, the Chinese hacker opened a chat window within the trojan, demanding to know what the researchers were doing.

“The dialog [is] an integrated function of the backdoor and the message is sent from the hacker who wrote the trojan. Amazing, isn’t it?,” the researchers wrote in a blog post.

“It seems that the hacker was online and he realised that we were debugging his baby.

“This is an impressive and first-time experience in my anti-virus career.”

Victims were directed to a booby-trapped video purporting to show how to farm the game’s boss character, Izual.

The malware could display a victim’s screen and running processes and allow the mouse and camera to be hijacked

The hacker then terminated the malware instance.
