This is the latest in a series of monthly charts counting down
the ten most frequently occurring viruses and hoaxes as compiled by
Sophos, a world leader in corporate anti-virus protection.
For November 2002, the chart is as follows, with the most
frequently occurring virus at number one:
dominates the chart for the second month as it continues to out-fox
users with its dual mode of attack - this worm can spread via email
and network shares," said Graham Cluley, senior technology
consultant, Sophos Anti-Virus. "It's important that all users
ensure they are protected against Bugbear because it implants code
that can log victims' keystrokes. This means hackers have a perfect
view of everything you type - this could include passwords, bank
account details and credit card numbers."
Also making a big impact this month was the new Braid worm. This is an
email aware worm with an attachment. However, if the recipient's
system is left unpatched against a Microsoft vulnerability, the
virus can run automatically, as soon as the offending email is
opened. Alongside keeping anti-virus protection up to date, Sophos
reminds users to patch against all known vulnerabilities and be
suspicious of all unsolicited emails.
The FunLove worm
and Spaces virus
make chart comebacks even though protection against these threats
was issued back in 1999.
Sophos detected 817 new viruses, worms and Trojan horses in
November, the total number it now protects against is 78,381.
