    • Adding Details of Authentication Methods to the Tenant Passwords and MFA Report \ V1.2 of the User Passwords and MFA report includes the names of authentication methods registered for user accounts. V1.3 expands the amount of detail reported for each method, such as the phone number used for SMS challenges, or the email address used for SSPR. It’s a small but important detail that’s useful to administrators. However, it also comes with a potential privacy issue, so the script must handle that too.
    • Leveraging OpenAI to Enhance Pull Request Management in Azure DevOps \ Our goal is to create an automation that significantly enhances the efficiency of our development process. A service hook is triggered when a new Pull Request is created in Azure DevOps, sending a webhook to an Azure Function. This function analyzes the request body, gets all commits in the Pull Request, and sends it to Open AI’s API, which generates a Pull Request message detailing all of the proposed changes from the commits and writes it back to the Azure DevOps Pull Request.
    • Create, configure, and delete system restore points with PowerShell, vssadmin.exe, and System Properties \ System restore points allow users to roll back Windows to an earlier state if problems arise. These points capture important system files, the registry, and drivers. In addition to using the System Properties applet, you can manage system restore points with PowerShell and vssadmin.exe.
    • How to Identify MFA Deployment Source in Microsoft 365 Using PowerShell \ Have you ever felt like managing multi-factor authentication (MFA) is more of a hurdle than a security measure? Constant MFA issues can be frustrating! Here are some common MFA issues; as you read, consider how you might address these challenges.
    • Connect to the Microsoft Entra PowerShell Module \ We all know that Microsoft deprecated the Azure AD PowerShell and MSOnline PowerShell modules. So, they advise us to migrate all the scripts to the MS Graph PowerShell. But finding the equivalent cmdlets and updating the scripts can be tough. Don’t worry! Microsoft heard our struggle!
    • Using Debug and Verbose parameters in PowerShell \ It's one of those things you forget, and you can get a lot more output when running scripts that will help you find out why things are not working as you expected. This small blog post will show you how to get more verbose and debug information.

    • Using PowerShell to Post Channel Messages with Teams Workflows \ The incoming webhook connector is a popular method to post information to Teams channels, but Microsoft seems set on retiring the Office connectors. The Teams post to channel workflow when a webhook request is received seems like is a possible replacement, but it's not just a matter of switching mechanisms. Some PowerShell magic is needed to create a suitable adaptive card to post to the channel, which is exactly what we explain how to do here.
    • Working with Calendar Permissions using the Microsoft Graph PowerShell SDK \ The Set-MailboxFolderPermission cmdlet is usually used to set calendar permissions, including the permission for the default user to allow everyone in an organization to see each other’s calendars. But you can use cmdlets from the Microsoft Graph PowerShell SDK too. The Graph SDK cmdlets are faster, but not enough to warrant replacing the Exchange cmdlet in scripts. We explain why here.
    • Automate Azure DevOps Work Item Updates with Azure Functions and the Azure DevOps API \ I use Azure DevOps Boards for agile project management, allowing me to plan, track, and discuss automation and DevOps tasks. I also create reporting dashboards from the data within the work items. One such metric I report on is how much time we save when implementing a new automation.

    • Version 1.9 of the Microsoft 365 Licensing Report \ The Microsoft 365 Licensing Report is a popular PowerShell script that's just been updated to V1.9 with a bunch of changes to highlight different aspects such as license costs for disabled user accounts and inactive user accounts. Copious use of some very dubious color choices makes the HTML report created by the script look very nice (if you're color blind) and the new version can generate an Excel worksheet.
    • PowerShellRun v0.7.0 \ In PowerShellRun v0.7.0, you can now add script blocks and script files as entries. If you are managing many PowerShell scripts, PowerShellRun will help you create a TUI script launcher.

  • Monitor Your Network with PowerShell [OC]

    I recently created a YouTube channel where I do deep dives into creating automations with PowerShell. Instead of just publishing the solutions I take you through the entire development process.

    In this video I go through creating an uptime monitor for multiple IP addresses that can ping each IP every minute. I go through the evolution of trying Test-NetConnection, then giving up and using dotnet objects for asynchronous execution. And finally, how to put that all together and get your results.

    This is only my fourth video, so any and all feedback on it is welcome.

    • To Splat or Not to Splat, That’s the Question \ Splatting is an optional PowerShell technique designed to make it easier to pass parameter values for cmdlets. It’s a personal choice whether to use splatting instead of passing values to individual parameters in the command line. Although the Microsoft Graph PowerShell SDK can be a little strange at times, you can use splatting with SDK cmdlets, even with some pretty complex parameters such as those used to filter objects.

Monitoring this process is important as it helps identify any issues that may arise and resolve them quickly. One way to monitor Active Directory replication is by using the Repadmin command-line tool. Repadmin provides a wealth of information about the replication status and health of a domain. However, manually checking the Repadmin output can be time-consuming and tedious, and running it manually every 30 minutes just to check if everything is great doesn't seem like a great idea. While PowerShell has its own commands around replication I've not found something as fast and reliable as repadmin /replsummary.

    PuTTY vulnerability vuln-p521-bias
  • If I understand correctly, the signatures generated by PuTTY aren’t perfectly random, so if someone got a hold of a bunch of keys from a server, they could figure out the pattern. It takes about 60 keys. This affects not just PuTTY, but also FileZilla, WinSCP, TortoiseGit, and TortoiseSVN.

    In other words if you have NIST P-521 keys, or any others using 521-bit ECDSA, you should revoke them and generate new key pairs. After you update your software.

    • How to Retrieve Loop Workspaces Data with PowerShell \ A previous attempt to write a script to report all Loop workspaces in a tenant was flawed because it only retrieved the first 200 workspaces. I hadn't realized that the Get-SPOContainer cmdlet supported an odd form of pagination to retrieve workspace data. In any case, I figured out how to page top find all available workspaces and updated the script. It's just another example of oddness in the SharePoint Online PowerShell module

ISV products have their place and fill many gaps, but arguing to dump PowerShell and use ISV products instead just can't be justified.

Let’s dive in and see how we can start using our existing PowerShell skills to start building lambdas.

    • New MSIdentityTools Cmdlet to Report OAuth Permissions \ The latest version of the MSIndentityTools PowerShell module includes the Export-MsIdAppConsentGrantReport cmdlet to generate a report of OAuth app permissions. Allied with the ImportExcel module, the cmdlet can produce a very nice workbook containing lots of information about permissions held by the apps in a tenant. But even better, you can export the data to PowerShell and use it in your scripts.
    • New enhancements to Get-AutopilotDiagnosticsCommunity \ It started off as a simple change: I was annoyed that the “Observed Timeline” in the output from the Get-AutopilotDiagnosticsCommunity (and the older Get-AutopilotDiagnostics script too) had events in the wrong order.
    • Perform Currency Conversions with PowerShell \ I’ve recently been working on a PowerShell module for exploring Azure costs (which I plan to blog about soon) and while doing so added some functionality to allow the costs to be converted between different currencies. It occurred to me that this functionality would be useful as a module of its own, and when I searched around I didn’t find too many recent examples for the same. As such I’ve now developed and published a module in the PowerShell Gallery and on GitHub called CurrencyConverter.

  • I installed some security cameras around my house and set up Shinobi using an old PC. Unfortunately the PC is too old to use the built-in detectors in Shinobi. So, I took my first dive into playing around with some image detectors.

    I wrote some python to download the daily recording from old PC to a newer one with a 3080 GPU. Then checks the videos for people. It will then trim the videos to only include times were there are people in frame. It cut my the storage requirements by over 95%.

  • Guidance on developing locally with Azure Automation
  • Just a heads up, I received confirmation from the product team that the AZUREPS_HOST_ENVIRONMENT environment variable is going away. They are moving the backend to containers. Also, the COMPUTERNAME one that was always "client" is going to change too. The COMPUTERNAME will now be "Sandbox-###" with # being random numbers. I started using the code block below in my runbooks to find if they are running in Azure or hybrid worker/locally. It accounts for the current and the updates that will be rolling out in the near future.

    $isHybridWorker = $true
    if (($env:computername) -eq "CLIENT") {
        $isHybridWorker = $false
    }
    elseif ($env:USERNAME -eq 'ContainerAdministrator') {
        $isHybridWorker = $false
    }

  • Guidance on developing locally with Azure Automation
  • Typically, when I have a script I need to test locally, I’ll comment out the identity connection command and just authenticate outside of my script. If I’m feeling real fancy, I’ll write a try/catch to attempt to authenticate first as the managed identity then if it fails prompt me for credentials. Not the most elegant solution, but it works.

    try {
        Add-AzAccount -Identity -SubscriptionId $SubscriptionId -ErrorAction Stop | Out-Null
    }    
    catch {
        Add-AzAccount -SubscriptionId $SubscriptionId
    }
    
  • Most and Least Verbose Programming Languages

  • Patch Tuesday 8 August 2023
  • Biggest things I'm seeing is CVE-2023-21709 for Exchange requires a PowerShell script to be run after patching. Also, CVE-2023-29328/29330 for Teams affect all devices (Windows, Mac, iOS, and Android).

  • What book would you recommend to explain to someone what you do for a living?
  • The book I wrote. When I first talked with the publisher he asked, "what skills would you look for in someone who wants to do your job?" And that's the premise I stuck with writing it.

  • Datalookup: Deep nested data filtering library
  • Interesting. As someone who mainly deals in PowerShell, this is very similar to the Where-Object clause and could save me some headaches when I need to work in Python.

  • "If you are happy and you know it", and what it does to your Spotify statistics.
  • From personal experience, it seems like things outside of your normal listening don't affect too much. At least in my case, my daughter making me play the Encanto soundtrack 250,000 times hasn't affected my weekly or daily playlists.

  • Firewall Alignment Chart
  • That's pretty similar with what happened with me and the train. Kept getting random drops from a plant. I went out to investigate and everything tested perfect and the network was staying up. That was until a freight train rolled by. Turns out AT&T had run the line by shoving a piece of PVC through the gravel between two cross-ties, then running the cable through it.

  • Firewall Alignment Chart
  • I've actually had an excavator take out my network. I've also had networks taken out by forklift, train, and a semi-truck towing three other semi-trucks.
