August Stats From Sophos

01 Sep 05:22

Sophos have published the most prevalent malware threats and hoaxes causing problems for computer users around the world during August 2006.

The report, compiled from Sophos's global network of monitoring stations, reveals little movement, with last month's four most prevalent pieces of malware retaining their positions. There are no new entries in August's chart and only one re-entry, the Mytob-E worm which last appeared in the chart in May 2005. This month's top two - Netsky-P and Mytob-AS - were also the most common in August 2005. Sophos maintains that a large number of computers connected to the internet are simply not protected against threats, which suggests that education on IT security is not making a global impact. Protection against Netsky-P has been available for more than two years, yet it remains the most widespread email worm.

Just one in 278 (0.4 per cent) emails are now virus infected, a significant decrease to August 2005 when one in every 50 emails circulating were viral. However, Sophos identified 1,998 new threats in August, bringing the total number of malware protected against to 186,665. The majority of the new threats (71.8 per cent) were Trojan horses, which, in most cases, are specifically targeted at particular groups of people and do not spread on their own.

The top ten list of malware in August 2006 reads as follows:

  1. Netsky-P - 19.9 per cent
  2. Mytob-AS - 15.8 per cent
  3. Bagle-Zip - 8.0 per cent
  4. Nyxem-D - 6.4 per cent
  5. Netsky-D - 4.4 per cent
  6. Mytob-C - 4.1 per cent
  7. Mytob-E - 3.2 per cent (return)
  8. Mydoom-O - 3.0 per cent
  9. Zafi-B - 2.7 per cent
  10. Mytob-FO - 1.5 per cent
