ChatOps: Setting up PoshBot for Microsoft Teams

ChatOps: Setting up PoshBot for Microsoft Teams

Comments 6 comments

PoshBot is a chat bot written in PowerShell and created by DevBlackOps. ‘It makes extensive use of classes introduced in PowerShell 5.0. PowerShell modules are loaded into PoshBot and instantly become available as bot commands.’1 PoshBot can do pretty much anything you configure it to do. You can have it create Azure servers, reset Active Directory passwords, create and modify help desk tickets, license Office 365 users, etc. ‘If you can write it in PowerShell, PoshBot can execute it.’1 

Important: PoshBot has some great documentation, make sure you bookmark and review it.

In this guide I will walk you through setting up PoshBot for Microsoft Teams. It’s a little more tedious than Slack (which is a few commands) but once you get it going it works flawless. Keep an eye out as I will be publishing more articles on different PoshBot plugins that I create which … Continue...

Connect and Navigate the Microsoft Graph API with PowerShell

Connect and Navigate the Microsoft Graph API with PowerShell

Graph is Microsoft’s RESTful API that allows you to interface directly with Azure AD, Office 365, Intune, SharePoint, Teams, OneNote, and a whole lot more. By using the Invoke-RestMethod PowerShell cmdlet we can connect and interact directly with the Graph API. The Invoke-RestMethod cmdlet sends HTTP and HTTPS requests to Representational State Transfer (REST) web services that returns richly structured data. PowerShell formats the response based on the data type. For an RSS or ATOM feed, PowerShell returns the Item or Entry XML nodes. For JavaScript Object Notation (JSON) or XML, PowerShell converts (or deserializes) the content into objects.1 In this article, I will walk you through setting up the Azure Application, assigning proper  permissions, Authentication and finally running queries against the Graph API. Once you understand how to properly authenticate and format queries you will see how powerful Graph can be for you and your organization.

Get a Teams Notification the Moment an Active Directory User gets Locked Out with PowerShell Using Webhooks

Get a Teams Notification the Moment an Active Directory User gets Locked Out with PowerShell Using Webhooks

Comments 25 comments

I have been recently using Teams as a central location for my organizations technical notifications instead of email as it provides a way for an entire Help Desk team to openly collaborate on the message and its contents. I recently got a request to get a Teams notification when a user gets locked out of their Active Directory account. By setting up a Webhook connector we can make it happen. The script will be triggered from Task Scheduler on Event ID 4740 which is created when a user gets locked out. By using “Search-ADAccount -LockedOut” we can return an array of locked out accounts, but by ordering it by lockout time we can ensure that we grab the most recent locked out user that corresponds to the security event.

I set the script and scheduled task up on my PDC because as far as I know, the actual lockout event … Continue...

In my previous post I went through setting up a Team’s webhook to send a daily message / notification of all your Active Directory users that have their password expiring in a week or less. This is valuable for an IT team as they can review users and work together on the within the same work space (team). In this post I will be setting up another scheduled task to send a daily message on Active Directory accounts that have not logged on in 90 days or more. I am also returning attributes like LockedOut, LastLogon, Enabled and more. The array of users is sorted, showing the users that have not logged on in the longest to the shortest. You can change the sort order to fit the needs of your environment. By using the cmdlet, “New-Timespan” I can get the amount of days since the user last logged on.… Continue...

Microsoft Teams has many connectors available including Incoming Webhook. “This provides an easy solution to post notifications / messages from any scripting language through JSON formatted web service call.”1

In this post I will show you how you can gather all of your users who have passwords expiring within a specified time range, and send a notification including all relevant information to a Teams Channel. In my example I will get all users who have passwords expiring in 7 days and less and have it notify my “Help Desk” Teams Channel.  

The current script will parse only enabled users because we don’t need to report on users, ‘passwordlastset’ attribute if the account isn’t even allowed to log in. It will also sort all of our data, so the users with passwords expiring the earliest will always be at the top of the message. The top description under, “Users … Continue...
