    First off,

    You should probably be configuring your Cisco devices to use RADIUS and
    some sort of token for authentication to keep from getting hacked.
    Cisco IOS's weakest point is probably it's authentication. You should
    also be patching your IOS and checking your configuration. Since IBM
    seems to be handling your problem for you, why don't you ask them?
    ISP's don't typically help you hunt a hacker, so they don't seem to be
    out of line on this. Your odds of finding the person who did this a
    very small. Yes, you need good qualifications to go hacker hunting. 1)
    "real" hackers don't like to be hunted and tend to make life difficult
    for those that hunt them and 2) they are usually good enough to be very
    difficult to trace. Even script kiddies can be quite difficult to trace.
