Überblick

Der USB Rubber Ducky ist ein Keystroke-Injection-Tool, das als generischer Flashspeicher getarnt ist. Von Hak5 entwickelt, erscheint er als Tastatur am Zielcomputer und kann vorprogrammierte Tastatureingabesequenzen mit übermenschlicher Geschwindigkeit ausführen. Er wird häufig für Penetrationstests, Social-Engineering-Bewertungen und Sicherheitsdemonstrationen verwendet.

⚠️ Warnung: Dieses Tool ist ausschließlich für autorisierte Penetrationstests und Sicherheitsbewertungen vorgesehen. Stellen Sie sicher, dass Sie eine entsprechende Autorisierung haben, bevor Sie es in irgendeiner Umgebung einsetzen.

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 ### Debugging von Payloadsbash 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% ENTER STRING Current time: STRING %TIME% ENTER ### Testumgebungbash

Set up isolated testing environment

Use virtual machines for payload development

Test on multiple OS versions and configurations

Verify payload behavior before deployment
