7MS #450: DIY Pentest Dropbox Tips - part 4

Hey friends! We're continuing our series on pentest dropbox building - specifically playing off last week's episode where we started talking about automating the OS builds that go on our dropboxes. Today we'll zoom in a little closer and talk about some of the specific scripting we do to get a Windows 2019 Active Directory Domain Controller installed and updated so that it's ready to electronically punch in the face with some of your mad pentesting skills! Specifically, we talk about these awesome commands:

tzutil /s "Central Standard Time" - this is handy to set the time zone of your server build

powercfg.exe -change -standby-timeout-ac 0 will stop your VM from falling asleep

Invoke-WebRequest "https://somesite/somefile.file" -OutFile "c:\some\path\somefile.file" is awesome for quickly downloading files you need. Couple it with Expand-Archive "C:\some\path\some.zip" "c:\path\to\where\you\want\to\extract\the\zip" to make auto-provisioning your toolkit even faster!

Don't like it that Server Manager loves to rear its dumb head upon every login? Kill the task for it with Get-ScheduledTask -TaskName ServerManager | Disable-ScheduledTask -Verbose. Byeeeeee!!!!

I love Chrome more than I love IE/Edge, so I auto install it with:

$Path = $env:TEMP; $Installer = "chrome_installer.exe"; Invoke-WebRequest "http://dl.google.com/chrome/install/375.126/chrome_installer.exe" -OutFile $Path\$Installer; Start-Process -FilePath $Path\$Installer -Args "/silent /install" -Verb RunAs -Wait; Remove-Item $Path\$Installer

Now get all the Windows updates!

Install-PackageProvider -name nuget -force Install-Module PSWindowsUpdate -force Import-Module PSWindowsUpdate Get-WindowsUpdate Install-WindowsUpdate -AcceptAll -IgnoreReboot

Then rename your machine:

Write-Host "Picking a new name for this machine...you'll need to provide your admin pw to do so" Rename-Computer -LocalCredential administrator -PassThru Write-Host "New name accepted!"

When you're ready to install Active Directory, you can grab the RSAT tools:

Write-Host "Lets install the RSAT tooleeeage!" add-windowsfeature -name rsat-adds

And then the AD domain services themselves:

Write-Host "Now lets install the AD domain services!" add-windowsfeature ad-domain-services

Then install the new forest:

install-addsforest -domainname your.domain -installdns -DomainNetbiosName yourdomain

7MS #121: Migrating from Tumblr to Ghost-Part 2

7MS #121: Migrating from Tumblr to Ghost-Part 2

Part 2 concludes my journey in moving 7ms.us from Tumblr to a Digital Ocean droplet running Ghost. Here are the key resources mentioned during the podcast: How to run multiple Ghost blogs on one DI VPS. The key takeaway here was that I had to upgrade to the $10 droplet (I did a "flexible" resize to add more proc/memory) and then the second instance of Ghost installed fine. Turning on CloudFlare SSL was easy. I chose flexible SSL since I wasn't using a "real" cert. I also wrote a rule to force HTTPs for all connections. And, just for grins, I turned on DNSSEC. Because...why not? :-) I picked a strong root password for my DI droplet, but I still don't like the idea of IPs banging on that connection all day and night. I followed this article on installing Fail2Ban to prevent my SSH login from being abused. There are a few IPs that I want to perma-ban, so I'm going to look throughthis article and this one which looks a tad easier. You can subscribe to the 7 Minute Security podcast here.

In this episode I talk about my adventures in moving my brianjohnson.tv Tumblr content over to a Digital Ocean hosted droplet running Ghost. I think you'll want to check this episode out, because in part 2 I talk about the challenges I faced in hosting multiple Ghost instances on one DI droplet. I will also be talking about how to enable CloudFlare SSL (for free!) as well as enabling Fail2Ban to keep annoying people/IPs from brute forcing your SSH root account!
