The door to the ground station's main control room is closed, but we found an old disabled GMS-06 defense droid. It seems it was being worked on when the bombs fell. There's still a USB key attached to it with a DFSec logo on it. We managed to read the key: it seems to be some kind of memory dump from the droid. Maybe we can use it to retrieve the entrance code to the station's control room. jmp .up .down: pop eax push 0xD68C67D9 call eax push 0x1154286C call eax push 0x1B1A1E19 call eax push 0x161B2D02 call eax push 0x1A372608 call eax push 0x2917094C call eax mov eax, 4 mov ebx, 1 mov ecx, esp mov edx, 0x18 int 0x80 mov eax, 1 dec ebx int 0x80 .up: call .down xor [esp+4], ebx mov ebx, [esp+4] ret
