I wonder what proportion of the development efforts go into securing these things. Imagine what would be happen, if these robots start getting hacked. A virus would no longer be just sitting inside a computer, it would manifest itself in a physical form. Hardcore viruses/trojans/worms/whatever can create physical implications: disrupting power grids, sabotaging nuclear programs[0], etc. But, even the basic forms of viruses which hackers will start out with, can cause serious consequences because of the physicality of these robots. And not just advanced robots like BostonDynamics', even basic autonomous robots have a high potential to do physical harm, if hacked. I somehow feel, people should focus more on securing these things vs empowering them with increased intelligence, agility and sheer strength. I would like to know, if security of these systems rely on the current state of computers, or do they have a different set of guidelines to abide by, considering that the attack vectors can be vastly different. With the current computer systems, most attacks are done via the internet. But with these, physical access can exploit a whole different range of vulnerabilities, which can be difficult for the bot the detect. Like, how the old PS/2 hardware keyloggers turned out to be quite difficult to detect[1]. What if someone just sticks a different kind of lens in front of the camera(s)/sensor(s) these systems rely on, which can just break all the math it is doing around visuals. Does the current state of the art of securing these systems, handle these cases ?
