I thought this was pretty interesting and worth sharing. Sophos recently came out with a report that states the top 10 malware threats that have been reported by customers. With this in mind, I think it is pretty safe to say that if they were the biggest malware threats in December, they will probably have their place this month as well.

Sophos, a world leader in IT security, has revealed the most prevalent malware threats and email hoaxes causing problems for computer users around the world during December 2006.

The figures, compiled from Sophos’s global network of monitoring stations, show that the long-established Dref malware has made an unexpected return to the top of the threat chart, thanks to two new variants currently causing problems for computer users worldwide.

The Dref-V mass-mailing worm, which poses as a New Year e-card, was discovered on December 30, 2006, and by the following day accounted for 93.7% of infected emails. As a result, Dref - which was first seen in July 2005 - has knocked last month’s main offender Stratio (also known as Stration) off the top of the chart. Stratio, currently in fourth place, now accounts for just 7.8% of the total.[more]
