7MS #420: Tales of Internal Pentest Pwnage - Part 17

Today's episode is a fun tale of pentest pwnage! Interestingly, to me this pentest had a ton of time-sponging issues on the front end, but the TTDA (Time to Domain Admin) was maybe my fastest ever.

I had to actually roll a fresh Kali VM to upload to the customer site, and I learned (the hard way) to make that VM disk as lean as possible. I got away with a 15 gig drive, and the OS+tools+updates took up about 12 gig.

One of the biggest lessons I learned from this experience is to make sure that not only is your Kali box updated before you take it to a customer site (see this script), but you should make sure you install all the tool dependencies beforehand as well (specifically, Eyewitness, Impacket and MITM6).

This pentest was also extremely time-boxed, so I tried to get as much bang out of it as possible. This included:

  • Capturing hashes with Responder
  • Checking for "Kerberoastable" accounts (GetUserSPNs.py -request -dc-ip x.x.x.x domain/user)
  • Check for MS14-025 (see this article)
  • Check for MS17-010 (nmap -Pn -p445 --open --max-hostgroup 3 --script smb-vuln-ms17-010 192.168.0.0/24 -oA vulnerable-2-eblue) and try this method of exploiting it
  • Check for DNS zone transfer (dnsrecon -d name.of.fqdn -t axf)
  • Test for egress filtering of ports 1-1024
  • Took a backup of AD "the Microsoft way" and then cracked with secretsdump:

sudo python ./secretsdump.py -ntds /loot/Active\ Directory/ntds.dit -system /loot/registry/SYSTEM -hashes lmhash:nthash LOCAL -outputfile /loot/ad-pw-dump

7MS #703: Tales of Pentest Pwnage – Part 79

Happy Thanksgiving week friends! Today we're celebrating a turkey and pie overload by sharing another fun tale of pentest pwnage! It involves using pygpoabuse to hijack a GPO and turn it into our pentesting puppet!  Muahahahahaah!!!!  Also: This week over at 7MinSec.club we looked at how to defend against some common SQL attacks We're very close to offering our brand new LPLITE:GOAD 3-day pentest course (likely in mid-January). It will get announced on 7MinSec.club first, so please make sure you're subscribed there (it's free!) Did you miss our talk called Should You Hire AI Run Your Next Pentest?  Check it out on YouTube!

7MS #702: Should You Hire AI to Run Your Next Pentest?

Hello friends, in today's episode I give an audio summary of a talk I gave this week at the MN GOVIT Symposium called "Should You Hire AI to Run Your Next Pentest?"  It's not a pro-AI celebration, nor is it an anti-AI bashing.  Rather, the talk focuses on my experiences using both free and paid AI services to guide me through an Active Directory penetration test.

7MS #700: Pretender

7MS #700: Pretender

Today is episode 700 of the 7MinSec podcast! Oh my gosh. My mom didn't think we could do it, but we did. Instead of a big blowout with huge news, giveaways and special guests, today is a pretty standard issue episode with a (nearly) 7-minute run time! The topic of today's episode is Pretender (which you can download here and read a lot more about here).  The tool authors explain the motivation behind the tool: "We designed pretender with the single purpose to obtain machine-in-the-middle positions combining the techniques of mitm6 and only the name resolution spoofing portion of Responder." On a recent pentest, I used Pretender's "dry run" mode to find a hostname (that didn't exist) that a ton of machines were querying for, and poisoned requests just for that host.  This type of targeted poisoning snagged me some helpful hashes that I was able to crack/relay, all while minimizing the risk of broader network disruption!

7MS #697: Pwning Ninja Hacker Academy – Part 4

7MS #697: Pwning Ninja Hacker Academy – Part 4

Today your pal and mine Joe "The Machine" Skeen pwn one of the two Ninja Hacker Academy domains! This pwnage included: Swiping service tickets in the name of high-priv users Dumping secrets from wmorkstations Disabling AV Extracting hashes of gMSA accounts We didn't get the second domain pwned, and so I was originally thinking about doing a part 5 in November, but changed my mind. Going forward, I'm thinking about doing longer, all-in-one hacking livestreams where we cover things like NHA from start to finish. My first thought would be to do one long livestream where we complete NHA start to finish. Would you be interested? Let me know at 7MinSec.club, as I'm thinking this could be an interesting piece of bonus content.
