7MS #432: Tales of Internal Network Pentest Pwnage - Part 21

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!

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.

Hey friends, today I talk about how fun it was two combine two cool pentest tactics, put them in a blender, and move from local admin to mid-tier system admin access (with full control over hundreds of systems)! The Tuesday TOOLSday video we did over at 7minsec.club will help bring this to life as well.

This week your pal and mine Joe "The Machine" Skeen kept picking away at pwning Ninja Hacker Academy. To review where we've been in parts 1 and 2: We found a SQL injection on a box called SQL, got a privileged Sliver beacon on it, and dumped mimikatz info From that dump, we used the SQL box hash to do a BloodHound run, which revealed that we had excessive permissions over the Computers OU We useddacledit.py to give ourselves too much permission on the Computers OU Today we: Did an RBCD attack against the WEB box Requested a service ticket to give us local admin superpowers on WEB Performed a secretsdump against WEB Struggled to do a mimikatz dump at the end of the episode (after we ended the stream I realized I could've just done the mimikatz dump because I had local admin access! Oh well, we'll pick things up again during part 4 next month!)
