LEGO-STYLE SIMULATOR Minecraft has been infiltrated by malware that lurks in downloadable 'skins' for player avatars and can wreak havoc by reformatting hard drives. The Minecraft malware was uncovered by security firm Avast, which reckons around 50,000 machines have been infected globally. Once downloaded into a victim's Minecraft game the malware reformats a machine's hard drives, delete its backups and system programs. "You Are Nailed, Buy A New Computer This Is A Piece Of Sh*t"; "You have maxed your internet usage for a lifetime"; "Your a** got glued"; were cited examples, which would suggest the malware was designed as a form of trolling rather than a criminally-motivated cyber attack. While this malware might seem pretty nasty, Alexej Savcin, malware analyst at Avast, noted it wasn't exactly a cutting-edge or sophisticated cyber attack "The malicious code is largely unimpressive and can be found on sites that provide step-by-step instructions on how to create viruses with Notepad," Savcin said.
