'Doomjuice' worm emerges, targets Microsoft
A new worm dubbed "Doomjuice" targeting Microsoft Corp.'s Web site emerged on the Internet on Monday, which security experts said slowed parts of the software maker's home page.
Doomjuice, which some are describing as a variant of the MyDoom worm, spreads via e-mail systems already infected with the first version, which became the fastest-spreading virus ever when it was unleashed on the Internet at the end of January.
"It's only looking for machines that are compromised by MyDoom A or B," said Vincent Gullotto, vice president of the anti-virus emergency response team at Network Associates Inc. He said it was not spreading as rapidly as the initial MyDoom worms.
Because Doomjuice spreads directly between infected computers, rather than via e-mail, experts said that it would not be accurate to call it a variant of MyDoom, which accounted for as many as one in five e-mails at its peak in late January.
But some computer security companies and Microsoft have taken to describing Doomjuice as a variant of MyDoom, naming it "MyDoom.C."
