Jurisdiction over which agency gets to do "cyber" stuff has been an open question for the last thirty years. You can make good arguments that it should be covered by the FBI, NSA, DHS, ATF, the secret service, etc etc.

(Yes, the Secret Service! The famous raid on Steve Jackson Games back in 1990 was actually carried out by Secret Service agents, who thought that GURPS Cyberpunk was an actual hacking manual.)
