Something you might try in terms of finding other accounts in the Uplink bank (if there are any) is to hack all bank accounts everywhere, look at the transfer logs, and check every source and dest IP against the Uplink bank. If either ever matches the uplink bank, then there's other accounts on the Uplink bank.
As for getting into the Uplink bank's admin section, you could try voice recording every person in the game and trying them one at a time.
A lot of time, if you ask me.
Lastly, I've noticed that the bank companies whose internal services systems have more security systems usually have better accounts in their banks.
For example, let's say company A and company B have their own banks...
Company A's internet services system has just a monitor, but company B has a monitor, proxy, and firewall.
I've noticed that usually, company B's bank's accounts usually have more money than company A's bank would.
