7MS #502: Building a Pentest Lab in Azure

Happy new year friends! Today I share the good, bad, ugly, and BROKEN things I've come across while migrating our Light Pentest LITE training lab from on-prem VMware ESXi to Azure. It has been a fun and frustrating process, but my hope is that some of the tips in today's episode will save you some time/headaches/money should you setup a pentesting training camp in the cloud.

Things I like

  • No longer relying on a single point of failure (Intel NUC, switch, ISP, etc.)

  • You can schedule VMs to auto-shutdown at a certain time each day, and even have Azure send you a notification before the shutdown so you can delay - or suspend altogether - the operation

Things I don't like

  • VMs are by default (I believe) joined to Azure AD, which I don't want. Here's how I got machines unjoined from Azure AD and then joined to my pwn.town domain:
dsregcmd /leave Add-Computer -DomainName pwn.town -Restart
  • Accidentally provision a VM in the wrong subnet? The fix may be rebuilding the flippin' VM (more info in today's episode).

  • Just about every operation takes for freakin' ever. And it's confusing because if you delete objects out of the portal, sometimes they don't actually disappear from the GUI for like 5-30 minutes.

  • Using backups and snapshots is archaic. You can take a snapshot in the GUI or PowerShell easy-peasy, but if you actually want to restore those snapshots you have to convert them to managed disks, then detach a VM's existing disk, and attach the freshly converted managed disks. This is a nightmare to do with PowerShell.

  • Deleting data is a headache. I understand Azure is probably trying to protect you against deleting stuff and not being able to get it back, but they night a right-click > "I know what I'm doing, DELETE THIS NOW" option. Otherwise you can end up in situations where in order to delete data, you have to disable soft delete, undelete deleted data, then re-delete it to actually make it go away. WTH, you say? This doc will help it make more sense (or not).

Things that are broken

  • Promiscuous mode - just plain does not work as far as I can tell. So I can't do protocol poisoning exercises with something like Inveigh.

  • Hashcat - I got CPU-based cracking working in ESXi by installing OpenCL drivers, but try as I may, I cannot get this working in Azure. I even submitted an issue to the hashcat forums but so far no replies.

On a personal note, it has been good knowing you because I'm about to spend all my money on a new hobby: indoor skydiving.

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.
