The W32/MyDoom-A worm has
launched a denial of service attack against the website belonging
to the software company SCO.
Computers infected by W32/MyDoom-A (known as "zombies") are
launching the attack, designed to knock SCO's website (www.sco.com)
off the internet, between 1 and 12 February. Infected computers are
also vulnerable to being hacked, and Sophos recommends affected
users update their anti-virus software and download a disinfection
"It's hard to say just how many infected computers may have
participated in the attack against SCO's website but it's likely to
be a significant number," said Graham Cluley, senior technology
consultant for Sophos. "The MyDoom worm is a serious problem, but
it is easy to detect, easy to prevent and not difficult to remove.
All users should ensure their computers are properly
In a statement SCO announced that their website was suffering
from a denial of service attack, and recommended customers and
partners visit an alternative version of their website not affected
by the attack: www.thescogroup.com.
