In the honeypot server we have him in, he is storing files in /dev/k4rd
Bash has been replaced with a "key logging" bash, het gets everything
you type, passwords included, emailed back to him at [email protected]

There seems to be ALOT of files in /dev/k4rd, a bin directory and etc.
He hacked the kernel so good that its VERY difficult to track his moves
without booting off another drive first.  We boot off a live linux cd
enviornment to do studies on what he is up to, but before we do that
we let him hack it up nicely so we get all his tricks.  Note: he cannot
really touch any other servers as he is stuck in a faked network enviornment
at this moment. Pinging yahoo.com for example will generate a reply and a
faked dns entry, but the packets never leave the zone he is in.

His motivation seems to be to gather nats affilaite and customer data.
He has an exploit that works on any and all nats installations.  Were
not going to release that until nats has been notified and had time to
secure it.

Were also seeing "traffic skimming" being attempted.
He is searching for scripts (that we put there just to see what he does
with them) that log traffic hits and etc.... He modifies these scripts so
that randomly, but rarely, hits are re-directed to a web site called
cgi-dnsl.com ( porn ).

I dont mean to be a brat to Sagonet, but this is always the source of this
hacker and his home never changes, its always on that single ip.
