Quote:

The new worm, DoomJuice.B, sets random HTTP headers to make it more difficult to filter the attack traffic, seeking to work around a defensive measure used by Microsoft earlier this week, when www.microsoft.com dropped requests without User-Agent headers to differentiate between Web browsers and the DDoS attack agents. The DoomJuice.B DDoS also initiates twice as many requests as its predecessor, launching 32-192 parallel threads instead of the 16-96 of DoomJuice.A.
