Monitoring with PowerShell: Monitoring failed logins for Office365

Leave a reply

So this was another request by a reader; he has MFA configured for all his users, but still wants to know when the failed logon count increases. Mostly so he can warn his users that a possible spear-phising attempt might also be imminent. We know that when brute force does not work, focussed bad actors will often try the next avenue of attack.

At his request i’ve made the following scripts, one will monitor all possible locations using your partner credentials. The other will monitor only one tenant. I personally like the latter better as I’ve integrated this into my RMM so it can run and alert per client, Also it’s a little faster.

The Script

The script is designed to run at least every 4 hours, but can be run even on a 5-10 minute basis. It will get all info for the previous 4 hours, If you want to decrease on increase this you can edit line 13. Getting the logs is based on Elliot’s script to get the unified logs here. To connect with MFA, use my other blog here to generate your Secure App Model credentials.

Get Failed Logon information for all tenants

$credential = Get-Credential
Connect-MsolService -Credential $credential
$customers = Get-msolpartnercontract -All
$FilteredLogs = @()
$FailedLogonCount = 0
foreach ($customer in $customers) {
    $InitDomain = $customer.DefaultDomainName
    $DelegatedOrgURL = "https://outlook.office365.com/powershell-liveid?DelegatedOrg=" + $InitDomain
    write-host "Connecting to $($customer.Name) Security Center"
    $s = New-PSSession -ConnectionUri $DelegatedOrgURL -Credential $credential -Authentication Basic -ConfigurationName Microsoft.Exchange -AllowRedirection
    Import-PSSession $s -CommandName Search-UnifiedAuditLog -AllowClobber
    write-host "Getting last 30 minutes of logs for $($customer.Name)"
    $startDate = (Get-Date).addhours(-4)
    $endDate = (Get-Date)
    $Logs = @()
    Write-Host "Retrieving logs for $($customer.name)" -ForegroundColor Blue
    do {
        $logs += Search-unifiedAuditLog -SessionCommand ReturnLargeSet -SessionId $customer.name -ResultSize 5000 -StartDate $startDate -EndDate $endDate -Operations userloginfailed #-SessionId "$($customer.name)"
        Write-Host "Retrieved $($logs.count) logs" -ForegroundColor Yellow
    }while ($Logs.count % 5000 -eq 0 -and $logs.count -ne 0)
   $FilteredLogs +=  $logs.auditdata | convertfrom-json -ErrorAction SilentlyContinue | Select-Object UserID, ClientIP | Group-Object -Property UserID
   Foreach($item in $FilteredLogs){
       if($item.name -ne $null){ $FailedLogonCount += $item.count; $FailedLogon += "$($Item.name) has $($item.count) failed logons from the following IPs: $($Item.group.ClientIP) `n" }
   }
}

if(!$FailedLogonCount){ $FailedLogon = "Healthy"}

Get failed logins for only one tenant

$TenantName = "TenantDomain.onmicrosoft.com"

$credential = Get-Credential
Connect-MsolService -Credential $credential
$FilteredLogs = @()
$FailedLogonCount = 0
$customer = Get-msolpartnercontract | Where-Object {$_.DefaultDomainName -eq $TenantName}

$InitDomain = $customer.DefaultDomainName
    $DelegatedOrgURL = "https://outlook.office365.com/powershell-liveid?DelegatedOrg=" + $InitDomain
    write-host "Connecting to $($customer.Name) Security Center"
    $s = New-PSSession -ConnectionUri $DelegatedOrgURL -Credential $credential -Authentication Basic -ConfigurationName Microsoft.Exchange -AllowRedirection
    Import-PSSession $s -CommandName Search-UnifiedAuditLog -AllowClobber
    write-host "Getting last 30 minutes of logs for $($customer.Name)"
    $startDate = (Get-Date).addhours(-4)
    $endDate = (Get-Date)
    $Logs = @()
    Write-Host "Retrieving logs for $($customer.name)" -ForegroundColor Blue
    do {
        $logs += Search-unifiedAuditLog -SessionCommand ReturnLargeSet -SessionId $customer.name -ResultSize 5000 -StartDate $startDate -EndDate $endDate -Operations userloginfailed #-SessionId "$($customer.name)"
        Write-Host "Retrieved $($logs.count) logs" -ForegroundColor Yellow
    }while ($Logs.count % 5000 -eq 0 -and $logs.count -ne 0)
   $FilteredLogs +=  $logs.auditdata | convertfrom-json -ErrorAction SilentlyContinue | Select-Object UserID, ClientIP | Group-Object -Property UserID
   Foreach($item in $FilteredLogs){
       if($item.name -ne $null){ $FailedLogonCount += $item.count; $FailedLogon += "$($Item.name) has $($item.count) failed logons from the following IPs: $($Item.group.ClientIP) `n" }
   }


if(!$FailedLogonCount){ $FailedLogon = "Healthy"}

You can choose to alert just on the FailedLogon variable, or alert based on the actual count via FailedLogonCount. As always, Happy Powershelling.

Documenting with PowerShell: Bulk edit configurations in IT-Glue

Leave a reply

I know last week I said I’d take a break from the monitoring blogs, but a MSP recently requested if I knew a way to mass-edit specific configuration items in IT-Glue. In his case, he was going to change the network configuration of devices and wanted a quicker way than to just click on 20 devices. It would be getting annoying fast to do that via the interface.

To make these edits easier for him, I’ve decided to quickly script the following for him:

    #####################################################################
    $APIKEy =  "APIKEYHERE"
    $APIEndpoint = "https://api.eu.itglue.com"
    $orgID = "ORGIDHERE"
    $NewGateway = "192.1.1.254"
    #####################################################################
    If(Get-Module -ListAvailable -Name "ITGlueAPI") {Import-module ITGlueAPI} Else { install-module ITGlueAPI -Force; import-module ITGlueAPI}
    #Settings IT-Glue logon information
    Add-ITGlueBaseURI -base_uri $APIEndpoint
    Add-ITGlueAPIKey $APIKEy
    $ConfigList = (Get-ITGlueConfigurations -page_size 1000 -organization_id $OrgID).data.attributes | Out-GridView -PassThru
    foreach($Config in $ConfigList){
    $ConfigID = ($config.'resource-url' -split "/")[-1]
    $UpdatedConfig = 
    @{
        type = 'Configurations'
        attributes = @{
                    "default-gateway" = $NewGateway
        }
    }
    Set-ITGlueConfigurations -id $ConfigID -data $UpdatedConfig
    }

This grabs all configurations for the specific organisation ID you’ve filled in, it then gives you a grid with all the current configurations. Using this grid you can select the configurations you’d want to make a change and apply the new gateway. Its very easy to modify other fields in bulk too, for this, check the API documentation here.

Anyway, I hope it helps some people struggling with bulk edits, and as always, happy PowerShelling!

Documenting with PowerShell Chapter 6: Documenting Active Directory groups

2 Replies

This will be the last post in the documenting with PowerShell series for a short while. I’ve enjoyed the series thoroughly but there are so many choices to blog about and I want to take a short break to be able to prepare the next series with all the requests I’ve been getting.

This time we will get al the current active directory groups, list all users in these groups, and even attach the contact as a tagged resource in IT-Glue. This way, you can look up a specific contact and find that exactly in which groups they’ve been added. It’s also pretty cool to combine this script with the previous blog found here.

And that’s it. This will help you document all your security and distribution groups. You’ll even see them in the contact sidebar, so you have a quick overview what user is in what groups.

And that’s it! as always, Happy PowerShelling.

Documenting with PowerShell Chapter 5: File share permissions

1 Reply

A lot of our clients struggle with permission management. Some of our clients practically want a daily permissions report to see if anything has changed. To make sure that our client can be sure we manage their permissions correctly we always upload the permission sets to our IT-glue documentation system. This way the client can see whenever permissions have changed and look at how the state of the permissions was last week, last month, or even last year.

Today I’ll be showing you how to upload permissions to IT-Glue using the IT-Glue API and the NTFSSecurity module. We’;ll also have a generic non-ITGlue version you can use with whatever documentation system you use.

IT-Glue version

We’ll be using the same base script as with the other chapters. Remember to set at the variables to your environment. The script will gather the permissions of the root folder specified, and all unique permissions of files and folders under that. It will skip over inherited permissions from the root.

The recursive depth is currently set to only look 2 folders deep. This is because our permission system does not allow unique permissions deeper than this. If your process does you should change the variable $RecursiveDepth.

Remember; it will make the flexible asset for you, if it does not yet exist.

Documenting with PowerShell Chapter 4: Network documentation for IT-Glue.

Leave a reply

In the last couple of blogs we spoke about how to handle passwords, passwords objects and tagging, and how to start documenting your servers. Today, We’re starting on the network side of documentation. Within IT-Glue it’s important to follow the IT-Glue standards so your documentation works with the relational database it was designed on.

There are a lot of tools that make automatic documation possible but pass around the fact that IT-Glue works best if you develop your documentation based on their best practices. This is why the documentation script we’ll make for networking has those in place: The script tags all available resources it can find, that are related to the network.

We currently tag all devices based on their primary IP in IT-Glue. You will need these filled in correctly to make sure the documentation script picks these up.

The Script

The script creates a flexible asset for you, with the required fields if the asset is not yet available. The flexible Asset will have 6 fields: the subnet, the gateway, the DNS servers, the DHCP servers, and the tagged devices. It also has a single textbox where a copy of the network scan will be added.

The script uses the PSnmap module for the network scan, it will automatically download this from the PSGallery. More info about PSNmap can be found here.

Documenting with PowerShell Chapter 3: Local Administrator Passwords solution

Leave a reply

As a good administrator does we always try to change the local administrator password on computers that we hand-out to clients, and disable it, so we only have to enable it when it’s required. Unfortunately changing it is sometimes forgotten during any process. Microsoft makes this easy when implementing LAPS. LAPS is a solution by Microsoft that helps you in randomizing Local Administrator Passwords, unfortunately LAPS relies on a domain environment. With more and more clients going Cloud-only this is not something we can use.

To resolve this issue you can use the script below as a LAPS alternative. Included are two versions as always: one for IT-Glue, and one to modify in any way you see fit.

The script generates a random password via Powershell of 24 alphanumeric characters, sets it for the local administrator called “Administrator”. There is also an option to rename this user to something else, as I strongly advise. We run the script at the end of our installation sequence or at initialisation of our RMM tool, whichever comes first.

So this uploads the password object and tags it to the correct device. if the device is not found, it still uploads the password but as an untagged password.

General version

The generalised version is located below. Please remember my warning as with previous blogs: This script prints the plain-text version of the password to the console. Modify this to upload the script to any general environment but be careful with this, as storing plaintext is just bad practice. 

#####################################################################
$ChangeAdminUsername = $false
$NewAdminUsername = "CompanyAdmin"
#####################################################################
add-type -AssemblyName System.Web
#This is the process we'll be perfoming to set the admin account.
$LocalAdminPassword = [System.Web.Security.Membership]::GeneratePassword(24,5)
If($ChangeAdminUsername -eq $false) {
Set-LocalUser -name "Administrator" -Password ($LocalAdminPassword | ConvertTo-SecureString -AsPlainText -Force) -PasswordNeverExpires:$true
} else {
New-LocalUser -Name $NewAdminUsername -Password ($LocalAdminPassword | ConvertTo-SecureString -AsPlainText -Force) -PasswordNeverExpires:$true
Add-LocalGroupMember -Group Administrators -Member $NewAdminUsername
Disable-LocalUser -Name "Administrator"
}
if($ChangeAdminUsername -eq $false ) { $username = "Administrator" } else { $Username = $NewAdminUsername }
write-host "$($Username) now has password $($LocalAdminPassword)"

And that’s it for today! The AMP can be found here, and as always, Happy PowerShelling.

Documenting with PowerShell: Chapter 2 – Documenting Bitlocker keys

Leave a reply

Our RMM system currently does not have support to securely store the bitlocker key inside of the RMM system itself. I’ve subscribed to the school of bitlocking everything that passes through my company, So also computers that sometimes never get connected to Azure AD, Active Directory to store the key in. We also get users that lost the USB drive or piece of paper that the key was stored on.

As we use a documentation system (IT-Glue) to store all our passwords, I figured why not try to also store our Bitlocker keys there, while tagging the device too so we can always find which device belongs to which key easily.

First for the none IT-Glue users I’ll generate a HTML file. With some small adaptation you can upload this to Confluence, ITBoost, or any other system you use. After that example, we’ll get onto IT-Glue again. So let’s get started!

Base script

The base script is the part of the script that captures the data that we want. In our case This will be the Bitlocker key, and output it an HTML file in C:\Temp\Temp.html You can use this script however you’d like.

$BitlockVolumes = Get-BitLockerVolume
#Some HTML to make the page pretty.
$head = @"
<script>
function myFunction() {
    const filter = document.querySelector('#myInput').value.toUpperCase();
    const trs = document.querySelectorAll('table tr:not(.header)');
    trs.forEach(tr => tr.style.display = [...tr.children].find(td => td.innerHTML.toUpperCase().includes(filter)) ? '' : 'none');
  }</script>

}

Now, that’s cool. This gives us a good ol’ HTML file. We now have a choice, use the previous script found here and adapt it to upload it to IT-Glue as a Flexible Asset or make the choice to upload it as an embedded password and tag the correct device. That sounds cooler to me!

This script looks for a configuration in your IT-Glue database based on the computer’s serial number. If it finds a match it uploads the bitlocker key as an embedded password, with the name “COMPUTERNAME – DRIVE:” as an example for my computer “DESKTOP-U3984 – C:” – We do this because the hostname might change over time and you’d want the keys to be uploaded separately.

IT-Glue unofficial backup script.

5 Replies

The last couple of weeks I’ve been focused on some API efforts for IT-Glue and was asked by a couple of partners if I couldn’t solve the problem that IT-Glue does not have a backup feature available. This makes it difficult to move away from the product, but also access you data in case of an emergency.

So to make sure that IT-Glue partners get some form of data portability and backups I’ve created the following script. The script connects to the IT-Glue API and creates a HTML and CSV export of all Flexible Assets and Passwords in IT-Glue.

It does not currently backup documents, as those are not exposed by the API. It also does not download attachments included on Flexible Assets. The export always creates 2 files; one HTML file for quick viewing, and a CSV file with all the information included.

I’ve also decided not to directly download all configurations as we store no data in there. If anyone wants to also download the configurations, let me know and I’ll edit the script a little.

Warning: The HTML files contain all your documentation, in plain-text format. Store this in a safe location or adapt the script to upload the data to your Azure Key Vault or secondary password management tool instead. Do not store these in a public location.

All you have to do is change the variables for your environment, APIKey, APIEndpoint, and the Export Directory.

Documenting with PowerShell: Chapter 1 – Server overview page

4 Replies

In the previous blog I’ve showed how to upload data to IT-Glue by creating a new flexible asset with two fields: a name field on which we perform a match if a document exists, and a field where we placed some data. This time, we’re going to upload an entire HTML file we’ll create by gathering data from the server we run the script on. So, let’s get started

The scripts below can also be downloaded for your RMM system, find the AMP file here.

Data gathering

First, We’ll make a list of all the data that is imported for us to have documented. For me, that would be the following list of information:

  • Server Name
  • Server type (A physical or virtual machine)
  • How much RAM the machine currently has assigned
  • The NIC configuration
  • What applications are installed
  • What server roles are installed
  • What the physical disk layout is
  • What the RAID layout is

Let’s get started with each of the data collection parts. In the following script we check if the model contains “Virtual” or “VMWare”. two signs that show if a machine is a physical or virtual machine.

$ComputerSystemInfo = Get-CimInstance -ClassName Win32_ComputerSystem
if($ComputerSystemInfo.model -match "Virtual" -or $ComputerSystemInfo.model -match "VMware") { $MachineType = "Virtual"} Else { $MachineType = "Physical"}

To get the amount of RAM we run the following oneliner

$RAM = (systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

Applications and roles are also quite easy to get

$ApplicationsFrag = Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Convertto-html -Fragment | select -skip 1
$ApplicationsTable = "<br/><table class=`"table table-bordered table-hover`" >" + $ApplicationsFrag

$RolesFrag = Get-WindowsFeature | Where-Object {$_.Installed -eq $True} | Select-Object displayname,name  | convertto-html -Fragment | Select-Object -Skip 1
$RolesTable = "<br/><table class=`"table table-bordered table-hover`" >" + $RolesFrag

For the NIC configuration, we need to do a little more work. We want the NIC configuration to show both IPv4 and IPv6 configurations. We also want to look up all NIC configurations, if a server has multiple NICs.

$networkName = Get-CimInstance -ClassName Win32_NetworkAdapter | Where-Object {$_.PhysicalAdapter -eq "True"} | Sort Index
$networkIP = Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration | Where-Object {$_.MACAddress -gt 0} | Sort Index
$networkSummary = New-Object -TypeName 'System.Collections.ArrayList'

foreach($nic in $networkName) {
    $nic_conf = $networkIP | Where-Object {$_.Index -eq $nic.Index}
 
    $networkDetails = New-Object PSObject -Property @{
        Index                = [int]$nic.Index;
        AdapterName         = [string]$nic.NetConnectionID;
        Manufacturer         = [string]$nic.Manufacturer;
        Description          = [string]$nic.Description;
        MACAddress           = [string]$nic.MACAddress;
        IPEnabled            = [bool]$nic_conf.IPEnabled;
        IPAddress            = [string]$nic_conf.IPAddress;
        IPSubnet             = [string]$nic_conf.IPSubnet;
        DefaultGateway       = [string]$nic_conf.DefaultIPGateway;
        DHCPEnabled          = [string]$nic_conf.DHCPEnabled;
        DHCPServer           = [string]$nic_conf.DHCPServer;
        DNSServerSearchOrder = [string]$nic_conf.DNSServerSearchOrder;
    }
    $networkSummary += $networkDetails
}
$NicRawConf = $networkSummary | select AdapterName,IPaddress,IPSubnet,DefaultGateway,DNSServerSearchOrder,MACAddress | Convertto-html -Fragment | select -Skip 1
$NicConf = "<br/><table class=`"table table-bordered table-hover`" >" + $NicRawConf

If a server is a physical machine, and a Dell server I also want to see the disk configuration. For this, you’ll need OpenManage installed.

if($machineType -eq "Physical" -and $ComputerSystemInfo.Manufacturer -matchf "Dell"){
$DiskLayoutRaw = omreport storage pdisk controller=0 -fmt cdv
$DiskLayoutSemi = $DiskLayoutRaw |  select-string -SimpleMatch "ID,Status," -context 0,($DiskLayoutRaw).Length | convertfrom-csv -Delimiter "," | select Name,Status,Capacity,State,"Bus Protocol","Product ID","Serial No.","Part Number",Media | convertto-html -Fragment
$DiskLayoutTable = "<br/><table class=`"table table-bordered table-hover`" >" + $DiskLayoutsemi

#Try to get RAID layout
$RAIDLayoutRaw = omreport storage vdisk controller=0 -fmt cdv
$RAIDLayoutSemi = $RAIDLayoutRaw |  select-string -SimpleMatch "ID,Status," -context 0,($RAIDLayoutRaw).Length | convertfrom-csv -Delimiter "," | select Name,Status,State,Layout,"Device Name","Read Policy","Write Policy",Media |  convertto-html -Fragment
$RAIDLayoutTable = "<br/><table class=`"table table-bordered table-hover`" >" + $RAIDLayoutsemi
}else {
    $RAIDLayoutTable = "Could not get physical disk info"
    $DiskLayoutTable = "Could not get physical disk info"
}

Putting all of that together will give us the following script, I’ve also added some headers to make the output HTML file look nice. You can use this as a stand-alone script.

#Server documentation script
$ComputerSystemInfo = Get-CimInstance -ClassName Win32_ComputerSystem

And that’s it! Happy PowerShelling! the next chapter will be how to upload the Bitlocker key for a client machine to IT-Glue as a password object, it will also tag all related devices, something that’s pretty cool!
