Folha de Dicas da Ferramenta de Injeção de Teclas USB Rubber Ducky

Visão Geral

O USB Rubber Ducky é uma ferramenta de injeção de teclas disfarçada de pen drive genérico. Criado pela Hak5, ele se apresenta como um teclado para o computador alvo e pode executar sequências de teclas pré-programadas em velocidades sobre-humanas. É comumente usado para testes de penetração, avaliações de engenharia social e demonstrações de segurança.

⚠️ Aviso: Esta ferramenta destina-se apenas a testes de penetração autorizados e avaliações de segurança. Certifique-se de ter autorização adequada antes de usar em qualquer ambiente.

Defensive Measures and Detection

USB Device Monitoring

# Monitor USB device insertions
Get-WinEvent -FilterHashtable @\\\\{LogName='System'; ID=20001,20003\\\\}|
Where-Object \\\\{$_.Message -like "*USB*"\\\\}

# Registry monitoring for USB devices
Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\USBSTOR\*\*"|
Select-Object FriendlyName, Mfg, Service

Keystroke Injection Detection

# Monitor for rapid keystroke patterns
# Look for superhuman typing speeds in logs
Get-WinEvent -FilterHashtable @\\\\{LogName='Security'; ID=4648,4624\\\\}|
Where-Object \\\\{$_.TimeCreated -gt (Get-Date).AddMinutes(-5)\\\\}

# Monitor for suspicious command patterns
Get-WinEvent -FilterHashtable @\\\\{LogName='Microsoft-Windows-PowerShell/Operational'; ID=4104\\\\}|
Where-Object \\\\{$_.Message -like "*DownloadString*" -or $_.Message -like "*IEX*"\\\\}

USB Port Restrictions

REM Disable USB storage devices via Group Policy
REM Computer Configuration > Administrative Templates > System > Removable Storage Access

REM Registry method to disable USB storage
reg add "HKLM\SYSTEM\CurrentControlSet\Services\USBSTOR" /v Start /t REG_DWORD /d 4 /f

Countermeasures

Endpoint Protection

# Enable PowerShell logging
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging" -Name EnableScriptBlockLogging -Value 1

# Enable command line auditing
auditpol /set /subcategory:"Process Creation" /success:enable

# Monitor for suspicious processes
Get-Process|Where-Object \\\\{$_.ProcessName -like "*powershell*" -and $_.MainWindowTitle -eq ""\\\\}

Network Monitoring

# Monitor for suspicious network connections
netstat -an|grep ESTABLISHED|grep -E "(4444|8080|443)"

# DNS monitoring for suspicious domains
# Monitor DNS logs for newly registered domains or suspicious TLDs

User Education

Key indicators of USB Rubber Ducky attacks:
1. Unexpected keyboard activity
2. Rapid text entry beyond human capability
3. Command prompts appearing automatically
4. Suspicious network activity after USB insertion
5. New scheduled tasks or startup programs

Troubleshooting

Common Issues

Issue: Payload not executing
Solution: Check keyboard layout, verify inject.bin file

Issue: Commands typing incorrectly
Solution: Verify keyboard layout matches target system

Issue: Timing issues
Solution: Increase DELAY values for slower systems

Issue: Antivirus detection
Solution: Use obfuscation techniques, test on similar AV
```### Depurando Payloads
```bash
REM Debug payload with visible output
DELAY 2000
GUI r
DELAY 500
STRING notepad
ENTER
DELAY 1000
STRING Payload executed successfully
ENTER
STRING Current user:
STRING %USERNAME%

```### Ambiente de Testes
```bash
# Set up isolated testing environment
# Use virtual machines for payload development
# Test on multiple OS versions and configurations
# Verify payload behavior before deployment
```## Considerações Legais e Éticas

### Uso Autorizado Apenas
- Obtenha permissão por escrito antes de testar
- Use apenas em ambientes controlados
- Documente todas as atividades de teste
- Siga práticas de divulgação responsável

### Requisitos de Conformidade
- Garanta o cumprimento das leis locais
- Siga as políticas de segurança organizacionais
- Mantenha a cadeia de custódia das evidências
- Proteja informações sensíveis descobertas
