[Overwatch] How does Sombra hack things?

She seems to just be some odd tech-guru that would even leave Technomancers scratching their heads. When she was younger, she seemed to have to be in physical contact with a computer, but now she has all this fancy holograms and stuff, so any ideas on how it all works?

For most of the combat "hacking" it's probably less of an actual "hack" and more like a brute force overload that takes the targeted machine a few seconds to compensate for, or the owner a few seconds to troubleshoot/repair. The only really innovative thing is probably her ability to affect things that should be airgapped but even then. It would explain why it's so close range and why it doesn't last very long. For everything else, like the medical pickups and the shenanigans at the robot factory, she probably has backdoors.
