In the 2007 film "Live Free or Die Hard", what is the villain's name?

In the 2007 film "Live Free or Die Hard," the villain is Thomas Gabriel.

Played by Timothy Olyphant, Gabriel is a former Department of Defense analyst who becomes the leader of a coordinated cyber-terrorist operation. His plan, called a “fire sale,” is designed to disrupt transportation, communications, financial systems, and other infrastructure across the United States.

Gabriel is not a traditional action-movie criminal seeking a single ransom. He believes the government ignored his warnings about weaknesses in America’s computer networks, and he uses that grievance to justify attacking the systems he once studied. Hacker Matt Farrell becomes crucial to exposing and stopping the operation, while John McClane handles the physical threat.

Simon Gruber and Hans Gruber are villains from earlier Die Hard films, so they are common quiz distractors. Burke is a character from a different installment and is not the antagonist of Live Free or Die Hard. Gabriel ultimately dies when McClane fires a gun through his own shoulder wound into Gabriel’s heart.
