Hypothetically, could you put a wireless modem in a game cartridge and use the cartridge as a key to hack into the CIA or something by putting the cartridge in a game console? Who would suspect a Nintendo 64 game cartridge for example, containing access to military secrets on a remote server?
And furthermore... they always suspect things like that when brought onto and off of top secret property. You are basically strip searched before you go in and after you leave.
"Hyperthetically (sic), could you put a wireless modem in a game cartidge..."
Sure. You can buy right now an SD memory card with built-in Wi-Fi so your digital camera can send photos directly to a computer in real time. The principle would be the same.
"...and use the cartridge as a key to hack into the CIA or something by putting the cartridge in a game console? Who would suspect a Nintendo 64 cartridge for example, as containing access to military secrets on a remote server?"
The CIA and NSA, among others, are so concerned about security that even toy bears with vocal recording capability are banned. No cell phones, no tape recorders, etc. are allowed in the secure facilities. Radio frequency monitors, x-rays, metal detectors, etc. are utilized at all entrances and exits, and so on.
(And still, the occasional security breach happens.)
Actually, I didn't mean for the cartridge to actually be taken onto any of these kinds of premises. Rather that their computer servers be hacked wirelessly by using a modem in a game cartridge using a game console.
Do you mean to get the modem inside HQ, then broadcast, from outside, a hack attack to and through the modem? That's plausible, but could you broadcast to the inside of HQ? They probably have some kind of signal shielding, like Gene Hackman in Enemy of the State.
