Tech news: A computer worm affecting Windows 2000 shut down systems across the United States , including those at CNN, ABC and The New York Times this afternoon. The reach and identity of the worm is still unknown, though some analysts are pointing to recently-discovered exploits in Windows 2000 and some versions of Windows XP. David Perry of Trend Micro said that the attack seems to have been triggered by a new worm called rbot.ebq. Johannes Ullrich, director of the Sans Institute, a network security firm in Jacksonville, Florida, said the outage also may have been caused by the Zotob worm, which was released last weekend. Several versions of the worm have been released, some as late as Tuesday, Ullrich said.
