"While the new variants of GameOver Zeus are today a fraction of the size of their predecessor, the resurgence of the popular malware illustrates the temporary nature of botnet takedown efforts. While the June takedown effort known as Operation Tovar was successful in disrupting GameOver Zeus, such efforts remain a game of whac-a-mole between law enfacement and cyber criminals. With one botnet down, others have emerged to take its place. While not a major threat today, NewGOZ continues to grow. One encouraging piece of news is the lack of a P2P command and control infrastructure this time around in favour of domain generation algorithms which can be easier to combat due to their predictability. NewGOZ is still being assembled and it remains to be seen what it will ultimately be used for."
