Allegedly, the rebels couldn't break into the subterranean part of the prison for a long time, because the guards have fled and didn't open the doors.
The doors were kept shut by an electronic system and no one knew how to bypass it.
In this case, "bruteforcing access" is quite literally what happened.
A real-world cryptographic incident, so to say.
But at the same time, you don't want to spend days slowly disassembling the system. They are hungry and possibly thirsty down there.
