7MS #502: Building a Pentest Lab in Azure

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 #580: Hacking Tommy Callahan - Part 3

Today me and my pal Paul from Project7 did a live hacking session and finally got the Callahan Auto brake pad Web app back online! Hopefully you enjoyed this hacking series. The feedback has been great, so we may have to take a crack at Billy in the near future as well.

7MS #579: Hacking Tommy Callahan - Part 2

Hey friends, today we're continuing our series on pwning the Tommy Boy VM on VulnHub VM! P.S. did you miss part one? Check it out on YouTube. Joe "The Machine" Skeen and I had a blast poking and prodding at the VM in hopes to fix the broken Callahan Auto brake-ordering Web app. Some tips/tricks we cover: It's always a good idea to look at a site's robots.txt file crunch is awesome for making wordlists fcrackzip is rad for cracking encrypted zip files dirbuster works well for busting into hidden files and subfolders exiftool works well to pull metadata out of images

7MS #578: Interview with Mike Toole of Blumira

7MS #578: Interview with Mike Toole of Blumira

Today I'm excited to share a featured interview with our new friend Mike Toole of Blumira. We talk about all things EDR, including: How does it differ from something like Windows Defender? What things do I need to keep in mind if I'm in the market for an EDR purchase? Is Mac EDR any good? How do attackers bypass EDR? Will AI create industructible malware, take over the human race and then use our bodies for batteries?

7MS #577: Tales of Pentest Pwnage - Part 48

Holy schnikes - this episode is actually 7 minutes long! What a concept! Anyway, today I give you a couple tips that have helped me pwn some internal networks the last few weeks, including: Getting a second (and third?) opinion on Active Directory Certificate Services vulnerabilities! Analyzing the root domain object in BloodHound to find some misconfigs that might equal instant domain admin access!

7MS #575: Annoying Attackers with ADHD - Part 2

7MS #575: Annoying Attackers with ADHD - Part 2

Hey friends! Today we're taking a second look at ADHD - Active Defense Harbinger Distribution - a cool VM full of tools designed to annoy/attribute/attack pesky attackers! The tools covered today include: PHP-HTTP-TARPIT A tool to confuse and waste bot/scanner/hacker time. Grab it here and check out our setup instructions: sudo git clone https://github.com/msigley/PHP-HTTP-Tarpit.git /opt/tarpit cd /opt/tarpit sudo mv la_brea.php /var/www/html/index.php cd /var/www/html/ # Delete the default HTMLM files that are there sudo rm DEFAULT .HTML FILES # Start/restart apache2 sudo service apache2 stop sudo service apache2 start # It's easier to see PHP-HTTP-TARPIT in action from command line: curl -i http://IP.RUNNING.THE.TARPIT Spidertrap This tool tangles Web visitors in a never-ending maze of pages with links! sudo git clone https://github.com/adhdproject/spidertrap.git /opt/spidertrap cd /opt/spidertrap # Open spidertrap.py and change listening port from 8080 to 80 sudo nano spidertrap.py # Run the trap sudo python3 spidertrap.py Weblabyrinth This tool presents visitors with a blurb of text from Alice in Wonderland. That text has links that takes them to...you guessed it...more Alice in Wonderland excerpts! I especially like that if you visit ANY folder or link inside Weblabyrinth, content is served (return code 200 for anything and everything). I had problems getting this running on a fresh Kali box so it's probably better to run right off the ADHD distro using their instructions.

Hey friends! Today we're looking at ADHD - Active Defense Harbinger Distribution - a cool VM full of tools designed to annoy/attribute/attack pesky attackers! ADHD gets you up and running with these tools quickly, but the distro hasn't been updated in a while, so I switched to a vanilla Kali system and setup a cowrie SSH honeypot as follows (see 7ms.us for full list of commands).
