If they are the off the shelf type that seems to be implied here then simple radio and GPS jamming works fine. If it is really unsophisticated then with a powerful enough signal you could hijack it and fly it somewhere safe.
Components might be off the shelf, but integration is custom and Im guessing it has a heavy Kalman filter which wont let you just blast spoofed _elevation changed by 1000m_ GPS signal and expect it to dive dive dive.
