Michael Lynn rose to fame in 2005 when Cisco Systems Inc. went to great lengths to try to censor his presentation on software vulnerabilities that would allow attackers to take over Cisco routers. Cisco threatened a lawsuit, ordering workers to rip 20 pages out of the program for the Black Hat security conference and destroy 2,000 CDs containing the presentation.
Lynn quit his employer, Internet Security Systems Inc., which he says pressured him to censor the talk as well. He gave it anyway, becoming a hacker hero. Lynn now works for Cisco rival Juniper Networks Inc. as a senior engineer.
