I cannot exactly recall the scene but I would bet it is one that they have pretty much made up for the film. You could probably knock one up similar based on linux if you had the skills and inclination.
The hacking dongle would, most likely, do nothing for real. If you had a secure system it would not allow anything on the dongle to run without the admin password and the admin password would be strongly typed and closely guarded.
However, consider the fact that actual hacking is quite boring to watch. It is mainly a numbers game combined with some specialist knowledge. Not very cinematic.
Hence film makers have to find ways of making hacking scenes quick and obvious to viewers, that is probably what the dongle is doing. It is a plot device that keeps the story going.
