The network security community is more than a little concerned about the latest variation of the continuously evolving GameOver Zeus botnet. The malware is responsible for siphoning over $100 million from bank accounts worldwide, and was thought to have been contained by a global crime-fighting effort.
The bot has morphed. It is still delivered in a zip file via phishing in email spam. But once launched, the newer version of the executable uses fast-flux hosting rather than the P2P code in the original malware. This means that it directs to domain names associated with IP several addresses and continuously cycles through different hosting locations until it can successfully download onto the targeted host computer.
Hackers are skilled business people who get up and go to work each day with one mission: to steal your assets using innovative tactics designed to get around your conventional security system.
Security expert Keren Elazari said at the Wired Money Conference in early July:
“How about we take a moment to learn from the bad guys. Because the tables have turned and criminals are innovating faster than most of us. They are innovating, automating, iterating, diversifying. The reality is the bad guys are extremely motivated and undeterred. They are not afraid to use new technologies or business models.”
