Google released some interesting data about the volume and types of attacks its spam detection software identified over the last quarter. According to Google, overall spam levels in the second quarter of 2009 were 53% higher than during the first quarter, and 6% higher than a year ago. Even though the total volume of spam dropped by 70% after the the takedown of the infamous McColo ISP, it only took four months for spam levels to get back to normal. Last month, 3FN, an other large ISP spam source was also shut down, but spam volume only dropped by about 30%, and chances are that the spam market will simply rebound within a few months, as new spammers get into the market.
