The networking giant and Internet Security Systems jointly filed a request Wednesday for a temporary restraining order against Michael Lynn and the organizers of the Black Hat security conference. The motion came after Lynn showed in a presentation how attackers could take over Cisco routers--a problem that he said could bring the Internet to its knees.

The filing in U.S. District Court for the Northern District of California asks the court to prevent Lynn and Black Hat from "further disclosing proprietary information belonging to Cisco and ISS," John Noh, a Cisco spokesman, said.

"It is our belief that the information that Lynn presented at Black Hat this morning is information that was illegally obtained and violated our intellectual property rights," Noh added.

The other shoe dropped.

At this point, the restraining order doesn't matter. He gave the talk. I know Mike has no intention of letting enough information get out for someone to actually exploit the flaws in the wild. Lets just hope for Mike's sake they decide this is futile and drop it.

I just heard that Mike is going to be on CNN tomorrow. Anderson Cooper's show.
