A well-known cyber-spying tool called Gh0st RAT is still being employed in stealthy malware attacks. A new report from security firm FireEye looks at 12 million reports of suspicious activity in 2012. Most of those incidents employed a remote access tool believed to have been developed in China. FireEye’s data shows attackers are using command-and-control servers to deliver instructions to malware in 184 countries now, a 42 percent increase over 2010. South Korea is one of the top callback destinations in the world, FireEye said.”]
