Pen-testers,
My company recently engaged on a penetration test for a large fortune
500 company. The first week of the test harvested no results to speak
of. However in the second week while re-scanning a particular subnet
where they hosted their staging systems we found a machine with a listening
port where there had not been one before. We discovered the port listening
was actually a backdoor (a common one) with a default password. We used
the portshell to gain entry onto the machine and one inside (it was a
win2k machine) we found a series of things. Firstly we had gained access
just shortly after the intruder as they were still present on the box
downloading from another box on the net. The downloads were going into
a sub directory normally used for another software package. The interesting
and troublesome part is related to what the intruder was downloading.
In short the items of interest were:
1. source code for what we think is an unpublished remote exploit for
a largely deployed service.
2. parts of commercial sourcecode for a vulnerability scanner from a
security vendor.
3. parts of commercial sourcecode for a firewall from another security
vendor.
4. what looks like a fairly advanced windows based kernel rootkit.
This stuff was also packaged with a whole series of other tools some
public some not. Our area of concern is what do we do now? The sourcecode
is obviously stolen and the exploit is likely unpublished and we are
left holding the bag to notify all of these vendors etc. Our concern
is that our client will likely be involved as well which is potentially
embarrassing to them. We have not yet acted on this (happened this morning)
and I would very much like any advice this list has to offer. In particular
if you have ever faced this type of problem before.
