Vulnerabilities in online gaming and virtual worlds lead to money laundering and other dangers, according to a new report by Dr. Igor Muttik, senior architect for McAfee Avert Labs. As revenues for virtual worlds topped $1.1 billion in 2006 and are expected to triple by 2009, online games are a hot target for cybercriminals looking to exploit vulnerabilities for money-making gains, who not only steal from online players, but also use virtual worlds to exchange funds achieved through their other criminal activities.
