The hack they were trying to interfere with reminds me of tempest stuff. I hope they didnt put safegaurds against a tempest like attack into the 360. If you could find a way to intercept the em/rf signals from the ram or cpu and read them. You could look inside the code being executed. They used to do this for video signals on old crt monitors. The high voltage signal's harmonics extended into the vfh range with a directional antenna a vhf radio and a sync regenerator yould could view text on a monitor from 1/4 of a mile away. If thru inductance could capture the signals from ram or cpu may be able to read code going thru them. I know its a long shot but just an idea.
