The way to evade capture is to remove all traces that would lead to the transfer of the money in either the stolen account or one belonging to you, and then make sure no trace can be made back to your gateway from the actual hacks involved.
If you really want to steal an assload of money, the way to do it is hack into the administrator account for a bank, get all of the account numbers and passwords, and then quickly go into each one, transferring the entire sum from each account into another one already there. Basically, you're framing some other guy, because all the money ends up in his account, but the real reason you're doing this is to pool everything is one place for the final transfer to yourself. Once all of the money from the bank is in one account and you've made sure you've gotten away with the hack (no need to worry about the transfers themselves, the money didn't go to you so you won't get in trouble), make yourself an account at that bank (it'll make it a lot easier to get rid of your tracks if it all happens at one bank), hack the pooled account, transfer to your new one, remove the transfer statement from both accounts, and cut the trail back to your gateway. Give yourself a bit of time to get away with the hack (Uplink will tell you), then if you want, transfer the amount to your Uplink account (you can do this legally), or just spend from there.
I did not intend to type a long post detailing the best way to steal lots of money from banks. But now that I have, I might as well post it and let you have the benefit of my wisdom, eh?
