John Schwartz writes in The New York Times this morning:

Malicious hackers could take down cellular networks in large cities by inundating their popular text-messaging services 
with the equivalent of spam, said computer security researchers, who will announce the findings of their research today.

Such an attack is possible, the researchers say, because cellphone companies provide the text-messaging service to 
their networks in a way that could allow an attacker who jams the message system to disable the voice network as well.

And because the message services are accessible through the Internet, cellular networks are open to the 
denial-of-service attacks that occur regularly online, in which computers send so many messages or commands to a target 
that the rogue data blocks other machines from connecting.

By pushing 165 messages a second into the network, said Patrick D. McDaniel, a professor of computer science and 
engineering at Pennsylvania State University and the lead researcher on the paper, "you can congest all of Manhattan."

UNIX was not designed to stop you from doing stupid things, because
that would also stop you from doing clever things.
