Why are the most well$-$publicized cyberattacks frequently investigated by agents with the FBI, the U$.$S$.$ Secret Service, and the State Department?

$$ because the United States introduced the Internet to the world and has an obligation to protect the world from misuse

$$ because these agencies are the world leaders in investigating and prosecuting cybercrime, which is not recognized as a crime in many European nations

O cybercrimes are not investigated by agents from these agencies; cybercrime is solely a local crime and investigated by local police

departments

O because large$-$scale cyberattacks frequently originate in other countries and cross state and national borders and are therefore

federal crimes
