The answer is simple - 100 machines. That's a very small botnet with some serious horsepower," he said.
Given the sheer size of the botnets being fueled by these attacks, the potential to create DDoS monster was obvious, he said.
A Trend Micro analysis earlier this month put some figures on the scale of what has been happening, with one backdoor campaign compromising as many as 100,000 domains in a single week.
