challenge description : While in Rome, a few heisters spotted a computer in the dumpster outside of a bank and took it. After brute forcing the computer credentials and getting in with "admin/password", there was a password-protected client database discovered. A Desktop sticky note had the following information: "To fellow bank employee - a way to remember each database PIN is that it is 4-digits ranging between 1000 and 9999". It appears the sticky note was auto-translating from another language as well - let's turn that off. Are you able to assist the heisters from here?

challenge hint : After scrolling down, there was additional text on the Desktop sticky note that says "wyptbt lza zlwalt". These bank employees should be removed from the payroll immediately...
