Top Ten Viruses & Hoaxes Reported to Sophos in January 2005

  • 02 February, 2005 11:50

<p>Sophos, a world leader in protecting businesses against spam and viruses, has published a report revealing the top ten viruses and hoaxes causing problems for businesses around the world during the month of January 2005.</p>
<p>The report, compiled from Sophos's global network of monitoring stations, shows that Zafi-D, which appeared at the end of 2004, maintains its position at the top of the chart for a second consecutive month.</p>
<p>The top ten viruses in January 2005 were as follows:</p>
2. W32/Netsky-P 19.4%
3. W32/Zafi-B 10.1%
4. W32/Sober-I 6.3%
5. W32/Netsky-D 3.2%
6. W32/Netsky-Z 3.1%
7. W32/Bagle-AA 2.1%
8. W32/Netsky-B 1.9%
9. W32/MyDoom-O 1.2%
10. W32/Netsky-C 1.1%</p>
<p>Others 7.6%</p>
<p>“It is disappointing to note that January's top-ten entries have all been stoppable for at least six weeks,” said Sean Richmond, Sophos’s Senior Technical Consultant for Australia and New Zealand. “And, while most of the entries are more than six months old they are still polluting the email streams of thousands of internet users."</p>
<p>"Zafi-D, which on the surface appears to be a Christmas greeting, seems to be tricking people as they return to work and is responsible for almost half of all reports. It would be far nicer for users to get back to work and find that these threats had been weeded out at the gateway level so they could get on and have a Happy New Year,” Richmond said.</p>
<p>With Sophos research showing that more than 4.3%, or one in 23 emails, circulating during the month of January were viral, Richmond suggests that some users might consider adopting New Year's resolutions along the lines of 'I will not double-click on random executable attachments' or 'This year I'll keep my anti-virus software up to date!'</p>
<p>"Keeping security software current is not an arduous task with automatic updating technology readily available,” Richmond said. “This allows desktops to be protected from less 'noisy' viruses and worms such as the seemingly endless rbot and sdbot variants that sneak across network shares rather than rely on email to spread."</p>
<p>Sophos analysed and protected against 1,329 new viruses in January. The total number of viruses Sophos now protects against is 99,829.</p>
