"It's good to see that there is more global information sharing going on, and that local governments are taking responsibility for cleaning up their own backyards, but with millions of bot hosts and more than 90 percent of those outside the U.S., I think they're still only putting a tiny dent in the problem at his point," said McPherson.
Other security industry experts agreed that it will take a lot more effort on the part of the international law enforcement community to have any noticeable impact on botnets and other cyber-criminals.
However, efforts such as Bot Roast will succeed in forcing botnet operators to increasingly worry that they may indeed be brought to justice for the crimes they commit, said Alan Paller, director of research for IT security training provider SANS Institute.
"At his point, the law enforcement community still can't get much done because so many of the perpetrators are located in so many places where there are no cooperative agreements," he said. "But what they are doing is increasing the risk and raising the cost of committing the crimes, which is just what law enforcement is good at; in the end they can't ever really stop people from trying to rob banks, but they can make it really dangerous and costly, just as they always have tried to."
