7MS #463: DIY Pentest Dropbox Tips - Part 5

In the last two episodes of this series (#449 and #450) we've been diving into how to not only speed up the process of spinning up a DIY pentest dropbox, but how to automate nearly the entire build process!

In today's episode we talk specifically about how to streamline the Windows 10 build process. As previously mentioned, this article is awesome for creating a core Win 10 answer file that will format C:, setup a local admin, login once to the configured desktop and then do whatever things you want it to do. Personally, I like having a single batch file get fired off that:

  • Sets the timezone with tzutil /s "Central Standard Time"

  • Stops the VM from falling asleep with powercfg.exe -change -standby-timeout-ac 0

  • Grabs and runs a PS file that does a ton of downloading and unzipping of files with:

invoke-webrequest https://somesite/somefile.zip -outfile c:\somewhere\somefile.zip expand-archive c:\somewhere\somefile.zip -destinationpath "c:\somewhere\extracted\"
  • Installs Windows updates with:
Install-PackageProvider -name nuget -force Install-Module PSWindowsUpdate -force Import-Module PSWindowsUpdate Get-WindowsUpdate Install-WindowsUpdate -AcceptAll -IgnoreReboot
  • Sets a new name for the 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!"
  • Does a set of actions depending on the IP range with this code (which sets the IP address to a variable and then does stuff if the machine sits in that subnet):
$ip = ((ipconfig | findstr [0-9].\.)[0]).Split()[-1] f ($ip -like "192.168.0.*") { Invoke-Webrequest https://somesite/somefile.ps1 -OutFile c:\someplace\somefile.ps1 }

Also, I talk in this episode about how I try to host these "seed" files as securely as possible using Amazon Lightsail instances, the built-in firewall, and LetsEncrypt.

This episode isn't about infosec exactly, but it talks about how using public resources like LinkedIn, Twitter and blogs to boost your "brand" (though I hate that word) and help you get more connected to the infosec community, job leads and more!

This episode is 90% a rant about how annoying carry-on luggage and air travel can be, and a 10% sprinkling of security sauce mixed in. Hence: sprinkles.

7MS #123: Doing a Redo Assessment

This episode talks about my experience in doing a "redo" security assessment, during which I struggled with the following questions: what's the best way to efficiently correct the erroneous information and make the customer happy without asking ALL the original questions over again? Especially when I have little to no time to prepare for the "redo" interview?

7MS #122: OFFTOPIC-An Apology to Elephants

7MS #122: OFFTOPIC-An Apology to Elephants

Preview76 wordsThis episode is about a documentary called An Apology to Elephants. It's all about the treatment (or mistreatment) of elephants, and the main message of the movie is, "Please don't go to the circus when it's in town, because you're supporting elephant abuse." Even if that message was a little heavy handed, I certainly will pass on tickets next time a circus act comes through town. You can subscribe to the 7 Minute Security podcast here.
