"Are hackers trying to get into your computer right now? And what are they up to? A study by the University of Maryland's A. James Clark School of Engineering is one of the first to quantify the near-constant rate of hacker attacks of computers with Internet access - every 39 seconds on average - and the non-secure usernames and passwords we use that give attackers more chance of success.
More Information: A summary of the study and a list of the top 1,000 usernames tried by hackers' dictionary scripts is available from the authors upon request."
