Research is showing that the ZeroAccess botnet is currently being used for two main purposes: Click fraud and Bitcoin mining. With the high level of worldwide infections, this particular botnet is capable of making an incredible amount of money: in excess of $100,000 a day.
Since cybercriminals are able to quickly make large sums of money using malware attacks that are getting harder to detect, you can count on the problem becoming much worse before it starts getting better.
