€200,000 reward for identifying creators of email worm

MYDOOM, the latest worm to infect computers over the internet, has become the fastest-spreading attack since last summer’s twin attacks by the Blaster worm and SoBig virus, computer security experts said yesterday.

Since appearing late Monday afternoon, the worm, also known as Novarg or Shimgapi, has spread rapidly, mostly in North America, accounting for one in nine messages globally.

The volume of messages clogged networks and appeared to be concentrated in corporate environments.
