I've had admin access on some servers for ages. One trick is, as said above, to be quick about it. Another is what I often recommend -- Monitor Bypass!
If you run the monitor bypass on the Monitor before you start cracking an admin pass, they will not actively trace you! Then all you need to do is bounce through 3-4 public servers, run bypass, run breaker, disconnect and you have admin. Best part is that some of the systems you hack this way will never/rarely change admin log/pass since they don't know they've been hacked
Clear a bounce log, though. Always.
