Caps are server sided and so is almost everything else making it impossible to hack them without actually having admin access to Bethesdas servers. The most you can hope for are aimbots, wall hacks/esp, and possibly speed hack. That being said if you pickup every gun, all armor, and outfits, then sell them to a vendor you can get cash rather quickly. So if you were to use a hack with the things I mentioned above you could easily run through a place and kill mobs instantly with headshots. Enough practice with that and a decent weapon will allow you to kill mobs like they are nothing and it will not matter if you are over encumbered either because with a speed hack set right you can go so fast your walk speed is much higher then normal sprint speed. Bethesda may change the way the server is setup later but as I said for now hacking money is not possible.
