This week’s Black Hat USA conference started with a bang Wednesday when an internet researcher quit his job in order to demonstrate a vulnerability in Cisco routers. Michael Lynn, until Wednesday morning a research analyst with Internet Security Systems (ISS), quit his job after his company decided not to give a presentation on the vulnerability. That led Lynn to quit because he believed the presentation was vital to the security and health of the Internet. The flaw Lynn described has already been patched by Cisco, but older versions of the company’s software remain at risk, he said. As Lynn left his presentation, several attendees shouted words of encouragement to Lynn. For more information on the story, check out our report here. Security
