Possible break in

[Alexandros Kyriakides <alex1 () MIT EDU>]

I am wondering if anyone can give me some help with this incident. The
only related thing I found on-line was this:

http://www.taclug.org/pipermail/taclug-general/2003-July/007821.html



The box I have is running linux mandrake 8.0. What I have found until now
is the following:


1) Two new binary files:

/usr/bin/dbproc
/usr/bin/gnorp



2) Appended at the end of inittab and rc.local:

inittab:
a:2345:once:/usr/bin/dbproc
a:2345:once:/bin/end

rc.local:
#Starting gnorp
/usr/bin/gnorp
#The End
/bin/end


3) lsattr gives:

suS-iadAcj--- /etc/inittab
suS-iadAcj--- /etc/rc.local




Has anyone seen this before? I am also interested in finding out how this
happened, if possible. Any help is greatly appreciated.


The two binary files can be found at:
