Prevention and Cure
MyDoom.F is the latest variant of the virus that launched a distributed denial of service (DDoS) attack against the SCO Web site early this month. The latest variant launches a DDoS attack against both www.microsoft.com and www.riaa.com if the infected computer's local system is dated between 17 and 22 of any month. The virus also opens a backdoor which will allow crackers to gain access to the computer.
"We firmly believe denial of service attacks that produce wave after wave of downed Web sites and infected emails are the new reality in the fight against spam, viruses and worms," said Scott Chasin, e-mail management company MX Logic's chief technology officer. "Just consider the number of broadband PCs, sitting on desks, without updated defenses and with 'always on' broadband connections - and you immediately understand the opportunity for these assaults."
MyDoom.F also randomly deletes files on the infected computer, a feature that has started to die out from viruses.
