Subject: /tmp/bob on compromised system

Greetings,
          We recently had a solaris 7 box compromised. We *think* that
the crackers got initial access through the oracle account which has
the default password :-(.

Network logs show a finger to the box (which sent 3 chars and returned
600, presumably the list of accounts). This was followed a few seconds
later by a telnet session. Logs were destroyed so we can not say with
any certainty which account was accessed.

The compromise was discovered when the admin noticed some odd files in
/tmp and unfortunately he deleted them. One of the files he remembers
deleting was /tmp/bob, now that rings a bell in my memory but I can't
find any reference to it on securityfocus or anywhere else. I assume
that this is a file left from a local elevation of priviledge attack
but I would like confirmation of that.

Cheers, Russell.
