Cisco hits back at flaw researcher

A raging discussion of this issue has been taking place since this story broke yesterday over on the North American Network Operators Group (NANOG) mailing list.

Joris Evers writes in C|Net News:

Cisco Systems has taken legal action to keep a researcher from further discussing a hack into its router software.

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," said John Noh, a Cisco spokesman.

"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.

Lynn decompiled Cisco's software for his research and by doing so violated the company's rights, Noh said.
