I have 100 clients that are joined to a domain. One of them is trying to do brute-force attack to the other clients. How can I get login failure logs on domain server about attacker logins?

I already enabled all audit policy settings that are related to the logins and I can see all the logs about login success/failure to the domain server but in this scenario I can not see any logs for client to client login failure.

  • AD does not log failures if they are for local accounts (like local admin or guest). Are you looking for these local account failures or for domain account failures on the clients?

  • Would enabling logon failures on local machines (via a GPO) and pushing logs to a centralized server (via nxlog for instance) be a solution?

I have a script that can help if you are on Windows Server:

function get-logonhistory{
Param (
 #get ip(127.0.0.1) and number of days you want get
 [string]$Computer = (Read-Host IP remoto do PC),
 [int]$Days = (Read-Host number of days)
 )
 cls
 $Result = @()
 Write-Host "wait..."
 $ELogs = Get-EventLog System -Source Microsoft-Windows-WinLogon -After (Get-Date).AddDays(-$Days) -ComputerName $Computer
 If ($ELogs)
 { Write-Host "processing..."
 ForEach ($Log in $ELogs)
 { If ($Log.InstanceId -eq 7001)
   { $ET = "Logon"
   }
   ElseIf ($Log.InstanceId -eq 7002)
   { $ET = "Logoff"
   }
   Else
   { Continue
   }
   $Result += New-Object PSObject -Property @{
    Time = $Log.TimeWritten
    'Event Type' = $ET
    User = (New-Object System.Security.Principal.SecurityIdentifier $Log.ReplacementStrings[1]).Translate([System.Security.Principal.NTAccount])
   }
 }
 $Result | Select Time,"Event Type",User | Sort Time -Descending | Out-GridView
 Write-Host "Done."
 }
 Else
 { Write-Host "Problem with ip $Computer."
 }
 }
#function call
get-logonhistory

Write-Host "Press any key ..."
#stop script to window dont close 
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

  • summarising the code would be helpful - this only grabs logs from a single computer, right?
