> the system does not regulate bolus insulin which is without a limit I understand that but the issue remains; all a hacker would have to do is set basal rate to 100000% and then you have a "bolus that kills you". Call it basal or bolus, it doesn't matter. The pump just pushes out insulin, and the amount can be controlled if you can hack the system.
