LAS VEGAS -- Security researcher Mike Lynn roiled the Black Hat conference Wednesday when he resigned from his job at Internet Security Systems to deliver a talk about a serious vulnerability in Cisco IOS, the operating system powering its routers, defying efforts by the router manufacturer and his former employer to block the presentation.
In the aftermath, Lynn reached a legal settlement with Cisco and ISS in which he agreed to erase his research material on the vulnerability, to keep secret the details of the attack, and to refrain from distributing copies of his presentation, among other concessions.
