Humanity on Edge: Final Quest

------ TOP SECRET ------ Assignment — July 16, 2120 Two years ago, the alien mothership was discovered for the first time. Since then, humanity attempted to establish diplomatic relations with the aliens. It failed — not least because humans themselves were too divided. Over the last months, key politicians and officials have been abducted worldwide. Intelligence circles assume the kidnappings were carried out by the aliens. Now, your mission: You are a space agent. You must protect humanity from alien tyranny and prevent a dystopian future. Can you overpower the aliens and seize control of their fleet? To board their mothership, you must crack the access console. You have only a single login attempt — one mistake and the aliens will detect the intrusion. The console shows the 4-digit code 765X. The first three digits are known; only the last digit X is unclear. Tip: The digit sum of the four numbers equals the smallest prime number that can be formed from that digit sum.
