Secondly, and a lot more worryingly so, is the indication that the 'Completely Automated Public Turing Test to Tell Computers and Humans Apart' or CAPTCHA entry validation system has been pwned.

If this is the case, then we may see spam levels increase in the months ahead." Not the best of news, it has to be said. But then neither is the fact that the number of new malicious websites blocked each and every day in July increased by a whopping 91 percent from 2,076 compared to June. This takes the daily total up to a rather depressing average of 3,968 new sites. So what is to blame? Other than the obvious dirty scumbag spammers answer, is the equally obvious SQL injection attacks one.
