Wonder why St. Louis is being targeted?
That map service is always like that. The company hosting is in St. Louis, and that's presumably where their largest "honeypot" is (they basically have PCs run scripts on websites, trying to get infected, then scan received packets to see what the attack was). It's kind of like measuring rape figures not by reported incidents, but by sticking an attractive young woman pretending to be drunk in a loud, poorly-lit night club with a bad reputation. "Attack targets" is meaningless, but "attack origins" should give an okay guesstimate of which countries have the most infected websites.
