Arcbank easter egg?

the formula for working out number of possibilities in a password is characters to the power of password length. For example we use digits 0 to 9 which is 10 characters total and take that to the power of 4 (usual length of a PIN number) and you get 10,000 Possible combinations. Perhaps if you know any LUA, you could write a program that bruteforces it (0000, 0001, 0002). Good luck man hope you find it!
