> spider.io has observed the Chameleon botnet targeting a cluster of at least 202 websites. 14 billion ad impressions are served across these 202 websites per month. The botnet accounts for at least 9 billion of these ad impressions.

The odd thing is that either these sites are already very big, or there are others ways they are getting 5 billion ad impressions.

A list of these 202 websites would be informative. I guess a number of them could be fake, to throw the scent off?
