it was possible to hack a protein synthesizer and insert arbitrary sequences (e.g. Ebola)

Infecting an RFID chip embedded in the hand strikes me as equivalent to infecting their cell phone. It really doesn't have much convergence unless the device is physiologically tied to the organism. Implant doesn't count unless it has a biological effect. An example of this might be a pace maker. Infect something like that and you have a digital virus converging with the biological realm of effect-on-host.
