Tsutomu Shimomura (下村 努 Shimomura Tsutomu?, born October 23, 1964) is an American physicist and computer security expert. He is known for helping the FBI track and arrest hacker Kevin Mitnick. Shimomura is currently CEO and CTO of Neofocal Systems.
At Caltech he studied under Nobel laureate Richard Feynman. After Caltech, he went on to work at Los Alamos National Laboratory, where he continued his hands-on education in the position of staff physicist with Brosl Hasslacher and others on subjects such as Lattice Gas Automata.
In 1989, he became a research scientist in computational physics at the University of California, San Diego, and senior fellow at the San Diego Supercomputer Center. Shimomura also became a noted computer security expert, working for the National Security Agency.
In 1992, he testified before Congress on issues regarding the privacy and security (or lack thereof) on cellular telephones.
He is best known for events in 1995, when he assisted with tracking down the "computer hacker" Kevin Mitnick. Shimomura and journalist John Markoff wrote a book, Takedown, about the pursuit, and the book was later adapted into a movie of the same name. Shimomura, himself, appeared in a brief cameo in the movie. The Mitnick case also inspired the Cyberthief and the Samurai, by Jeff Goodell.
Shimomura worked for Sun Microsystems during the late 1990s.
|“||It was in front of Congress, and I was testifying to a Congressional subcommittee. And here was this guy in sandals and, like, ragged-ass cutoffs, and the rest of us were done up in ties [...] giving our best sort of 'yes, we're in front of Congress' thing and Shimomura is there in this surfer gear.||”|
Kevin Mitnick and others have raised legal and ethical questions concerning Shimomura's involvement in his case. California author Jonathan Littman wrote a 1997 book about the case called The Fugitive Game: Online with Kevin Mitnick, in which he presented Mitnick's side of the story, which was a very different version from the events written in Shimomura and Markoff's Takedown. In his book, Littman made allegations of journalistic impropriety against Markoff and of the legality of Shimomura's involvement in the matter, as well as suggesting that many parts of Takedown were made up for self-serving purposes by its authors. Mitnick's autobiography, Ghost in the Wires, further expands on concerns that Shimomura's involvement in the case was both unethical and illegal.
