Jennifer Granick, Lynn's lawyer, is being hailed as his savior. T-shirts with anti-Cisco prints have been selling well, and hackers have set up a PayPal account to collect money for a legal defense fund. While corporate America may frown at Lynn's actions, he is a hero at Defcon, the more informal gathering of security professionals and enthusiasts that follows Black Hat. Cisco and ISS subsequently sued Lynn and the Black Hat organizers, charging public disclosure of illegally obtained proprietary information. He did so in defiance of Cisco and ISS, which had agreed to cancel the talk.

Lynn stirred the Black Hat security conference here Wednesday by quitting his job at ISS, a move taken so that he could demonstrate that he could gain control of a Cisco router by exploiting a security flaw. LAS VEGAS-Attendees at the Defcon security event denounced the way Cisco Systems and Internet Security Systems dealt with Michael Lynn after he showed that it is possible to hack Cisco routers.
