This headline is from a New York Times article published in the online edition this afternoon. The report says, in part:

Until last Friday television screens and newspapers abroad were flooded with scenes of tens of thousands of red-robed monks in the streets and of chaos and violence as the junta stamped out the biggest popular uprising there in two decades.

But then the images, text messages and posts stopped, shut down by generals who belatedly grasped the power of the Internet to jeopardize their crackdown.

“Finally they realized that this was their biggest enemy, and they took it down,” said Aung Zaw, editor of an exile magazine called Irrawaddy, whose Web site has been a leading source of news over the past weeks.

His Web site has been attacked by a virus whose timing raises the possibility that the military government has a few skilled hackers in its ranks.
