Threat Hunting with PowerShell - Security even with a small budget - there is no excuse!
Dear Threat Hunter, Lack of IT security is often excused by little or no available money. In my view, this is a very poor excuse. In this article I will try to give you a jump start on how to investigate threats with PowerShell. Is this a comprehensive and conclusive list of how you can find or detect threats/threats? NO, absolutely not. But it is meant to provide you with the support that you need to move forward on your own. Let's talk about the "general conditions": 1. If you use the PowerShell scripts I show/explain in this article, this is entirely your responsibility. I use the scripts in different situations, they are not dangerous, but you should already know what you are doing. 2. Written permission! If you are not sure if you are allowed to do an investigation, organize a written permission from your supervisor. 3. In the different scripts I sometimes (for this article deliberately) use standard search words like "malware", "malicious", "hacker" etc. Such search patterns/search words need to be customized, of course. These simply serve as an example. 4. The last part of the article examines some Microsoft cloud services. I am absolutely aware that there are a huge number of tools for hunting in the Microsoft cloud services. It starts with Azure Sentinel and continues with Cloud App Security. Since the focus is on a small budget, I'll leave those tools on the side. Introduction: So first, why should you use PowerShell for threat hunting? PowerShell is a useful threat hunting tool because it is a powerful scripting language and a platform for automating tools and accessing data across any Windows environment. It allows you to quickly gather information from various sources such as event logs, registries, files, and processes. Additionally, it can also be easily integrated with other tools and technologies making it a flexible and efficient tool for threat hunting. Some common use cases for PowerShell in the threat hunting environment include automated collection of log data, identification of unusual behavior anomalies in the system, the discovery of malware or malicious activity by known signatures or patterns or behaviors. These are just a few examples of how PowerShell can be used in a threat hunting capacity. Its versatility and ability to access and manipulate data from across the Windows environment make it a very valuable tool for any security professional. Threat Hunting in PowerShell - Use Cases: All right. So now that we understand where PowerShell can benefit an organization from a threat hunting perspective. Let's take a deeper look at some of the actual use cases you might encounter on a day to day basis, first being identify malicious processor files. So specifically, you can conduct raw file analysis to sift through different data shares to look for particular files in question whether that be a signature or even an extension of a certain file being able to quickly search and triage through files is an extreme benefit of using PowerShell for threat hunting. But how exactly do we start, what can we use as a guide? For example, the MITRE ATT&CK Framework. Here are a few examples: Indicator Removal: Clear Windows Event Logs https://attack.mitre.org/techniques/T1070/001/ Event Triggered Execution: Installer Packages https://attack.mitre.org/techniques/T1546/016/ Hide Artifacts: NTFS File Attributes https://attack.mitre.org/techniques/T1564/004/ Command and Scripting Interpreter: PowerShell https://attack.mitre.org/techniques/T1059/001/ Command and Scripting Interpreter: Windows Command Shell https://attack.mitre.org/techniques/T1059/003/ Event Triggered Execution: Windows Management Instrumentation Event Subscription https://attack.mitre.org/techniques/T1546/003/ Credentials from Password Stores: Windows Credential Manager https://attack.mitre.org/techniques/T1555/004/ Abuse Elevation Control Mechanism: Bypass User Account Control https://attack.mitre.org/techniques/T1548/002/ The MITRE ATT@CK framework provides a comprehensive and regularly updated overview of tactics, techniques, and procedures (TTPs) used by various threat actors.

Summary: Is this the best tactic to hunt for threats? No! There are many different tactics/techniques to search for threats. First of all, there are a huge number of different tools that can be used, for example SIEM/SOAR (Security Information and Event Management/Security Orchestration, Automation and Response). These tools are really great, sometimes cost a lot and often it takes a lot of knowledge to use such tools. But what is the use of such tools if the information generated by these tools cannot be understood properly, not very much. For this reason, I have tried in this article with simple tools to generate information that hopefully can be interpreted. Is finished here at this point. NO, the journey continues. The examples in this article are neither exhaustive nor complete, but they should give you a starting point. I hope you can build on this foundation. I hope that this information is helpful to you and that you have received a good "little" foundation. But I still hope that this information is helpful for you.

Connect-SPOService not working in PowerShell 7
Hi all, I'm having some issues getting Connect-SPOService working in PowerShell 7 (7.2.4). It works fine in Windows PowerShell (5.1.22), however it will always generate errors when trying to us it in PS 7 which I've listed below. Firstly if I open Windows PS, I can use it straight away, however if I open PS 7, I have to import the module in order to use it. I guess I can fix this with a profile adjustment, but is there a reason why this would be the case? Secondly even when it's been imported, if I try to connect with the following, I get an error: Connect-SPOService -Url https://***-admin.sharepoint.com Connect-SPOService: No valid OAuth 2.0 authentication session exists Never seen this before in Windows PS and I'm not sure how to resolve it so I tried connecting with this instead. Still got an error but a different one this time: Connect-SPOService -Url https://***-admin.sharepoint.com -Credential ***@***.com Connect-SPOService: The sign-in name or password does not match one in the Microsoft account system. I know these are the right credientials as again they work fine in Windows PS. This lead me to think that something still wasn't being imported correctly into PS 7, so I had a look at the modes, and I noticed that the ExportedCommands don't appear when Get-Module is run in PS 7, but again they do in Windows PS. I'm guessing this could be part of the issue but I'm not sure how to resolve it. From what I can see everything appears fine, but I'm sure I'm missing something here. I've tried setting my ExecutionPolicy to unrestricted in case that was the problem, however it didn't appear to change anything. If anyone has seen this before or could provide any help it would be greatly appreciated. I realise that I could just use Windows PS, but it feels like PS 7 is the way forward and it would be nice to better understand why this is happening. Many thanks in advance.Facing issue in installing the Pnp PowerShell Module for SharePoint 2013/Online

Get SharePoint Site URL of an individual Microsoft Team
I found the https://office365itpros.com/2019/03/27/finding-sharepoint-urls-teams/. I want to use the same concept but only return one SP site URL so I can use the URL to create a folder in that Team. $Teams = (Get-Team |Select GroupId, DisplayName) ForEach ($T in $Teams) { $SPOURl = (Get-UnifiedGroup -Identity $T.GroupId | Select -ExpandProperty SharePointSiteURL) Write-Host "URL for the" $T.DisplayName "team is" $SPOURL } It would be easiest to start with getting the Team by displayname then taking the group ID and using that. All the individual versions of -expandproperty SharePointURL have not worked for me yet. Any advice? Get-Team -DisplayName $Team | Select GroupIdScript for Teams-Chat backup

PSVersion：7.1.3 OS：Microsoft Windows 10.0.19042 OneDrive Version：21.052.0314.0001 (Office 365 A1) Descriptions Cannot remove nonempty folder in OneDrive directory Step to reproduce 1. Launch PowerShell in OneDrive directory PS C:\Users\MyUserName\OneDrive> 2. Try to use Remove-Item cmdlet to remove a nonempty folder in this directory, for example: the .\test\ folder PS C:\Users\MyUserName\OneDrive> Remove-Item .\test\ Expected result Without the -Recurse parameter, PowerShell should return a confirm message, such as Confirm The item at C:\Users\MyUserName\OneDrive\test\ has children and the Recurse parameter was not specified. If you continue, all children will be removed with the item. Are you sure you want to continue? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): Actual result PowerShell return a error message Remove-Item: Cannot remove item C:\Users\MyUserName\OneDrive\test\: The directory is not empty. : 'C:\Users\MyUserName\OneDrive\test\' Note 1. PowerShell and Administrator:PowerShell get the same result; 2. If I exit OneDrive process and create a new nonempty folder under OneDrive directory, PowerShell can remove it as normal; 3. CMD can remove the folder successfully, which means I can use cmd.exe /C "rd /s test" in PowerShell to remove the folder too. But I want to accomplish this just by PowerShell cmdlet; 4. Get-ChildItem cmdlet shows that the mode of normal folders (not synced by OneDrive) is 'd'(directory), but the mode of synced folders is 'l'(link).
