Sophos, a world leader in protecting businesses against spam and

problems for businesses around the world.
The report, which examines virus and hoax reports in the month

the most commonly reported, while the Hotmail hoax takes the top
spot for a fifth month running.
The top ten viruses in December 2003 were as follows:
"The Sober-C worm, which spread by email and peer-to-peer
networks, was first seen on 21 December, yet it still managed to be
the most reported worm of the month," said Carole Theriault,
security consultant at Sophos. "Despite Sober-C's top position on
the chart, the different Mimail variants accounted for nearly a
third of all reports at 29.7%."
Sophos analysed and protected against 730 new viruses in
December. The total number of viruses Sophos now protects against
is 86,811.
"With more than 700 new viruses arriving in our lab during
December, it's fair to say that virus writers were not interested
in taking a break over the festive period," continued
Theriault.
The top ten hoaxes reported to Sophos during December are as
