Why Old SQL Worms Won't Die 64
narramissic writes "In a recent ITworld article, Security researcher Brent Huston ponders how it is that versions of SQL worms dating back to 2002 represent nearly 70% of all malicious traffic on the Internet today. 'I have made a few attempts to backtrack hosts that perform the scans and at first blush many show the signs of common botnet infections. Most are not running exposed SQL themselves, so that means that the code has likely been implemented into many bot-net exploitation frameworks. Perhaps the bot masters have the idea that when they infiltrate a commercial network, the SQL exploits will be available and useful to them? My assessment team says this is pretty true. Even today, they find blank "sa" passwords and other age-old SQL issues inside major corporate clients. So perhaps, that is why these old exploits continue to thrive."
