PowerShell Token Grabber

Malware targeting Windows systems that utilizes PowerShell for the purpose of data exfiltration. All information collected is sent using Discord webhooks.

Important

As of 2024-02-14, PowerShell-Token-Grabber is detected by AMSI (malware-encyclopedia). You need to obfuscate the generated payload in order to use it effectively.

Usage

Create a Webhook on your Discord Server. I recommend creating a new server.
After creating a server go to Edit channel > Integrations > Webhooks > Create Webhook
Copy the Webhook URL
Download main.ps1
Open main.ps1 and replace YOUR_WEBHOOK_HERE in line 30 with your webhook or use the builder.

Want to obfuscate the code ?

Use Invoke-Obfuscation.
Or use Somalifuscator for .bat files

Features

Telegram Session Stealer Usage :

After the exfiltrated data is uploaded to your discord webhook, download the compressed file KDOT.zip, extract it on your PC, inside that folder there will also be another subfolder Messaging Sessions , inside this subfolder you will find the Telegram folder. Now, copy the tdata folder from Telegram folder and paste it in the directory below:

%userprofile%\AppData\Roaming\Telegram Desktop

Before pasting the tdata folder, ensure that you have deleted the existing tdata folder on your PC.

Note

The other session stealers can be utilized by applying the technique above

🗑 Uninstaller (Removes the Scheduled Task, Script Folder, ExclusionPaths and Resets Hosts File)

Open a new Elevated Powershell Console then copy & paste the contents below

$ErrorActionPreference = "SilentlyContinue"
function Cleanup {
  Unregister-ScheduledTask -TaskName "KDOT" -Confirm:$False
  Remove-Item -Path "$env:appdata\KDOT" -force -recurse
  Remove-MpPreference -ExclusionPath "$env:APPDATA\KDOT"
  Remove-MpPreference -ExclusionPath "$env:LOCALAPPDATA\Temp"
$resethostsfile = @'

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
# localhost name resolution is handle within DNS itself.
#       127.0.0.1       localhost
#       ::1             localhost

  Write-Host "[~] Successfully Uninstalled !" -ForegroundColor Green
}
