It scans the local airspace for wireless networks that have WPS enabled.
WinPcap was officially discontinued in 2018. It does not natively support Windows 10 or Windows 11 network driver architectures, often leading to system crashes (Blue Screens of Death) or driver incompatibility errors.
The combination of , JumpStart , and WinPcap represents a well-known, albeit outdated, toolset from the mid-2010s for assessing the security of WPS-enabled WiFi routers. Its "exclusive" nature comes from its pre-packaged form, which bundles all necessary components for a specific kind of security test. While it can be an effective educational tool to demonstrate the dangers of leaving WPS enabled on older routers, its practical use is limited by modern router security measures and the deprecation of its underlying WinPcap library.
This is often the most confusing component for modern users. is an open-source library for Windows that allows software to capture and transmit network data packets bypassing the protocol stack.

Download the official WinPcap 4.1.3 installer. During installation, check the box that says "Automatically start the WinPcap driver at boot time." Restart your PC. Do not skip the restart—the JumpStart script checks for active kernel drivers.
The existence of tools like Dumpper highlights severe flaws inherent in legacy WPS implementations. To protect wireless infrastructure against automated pin-exploitation tools, network administrators should implement the following defensive configurations:
: It displays vital router details like MAC addresses, signal strength, and WPS status.
: Upgrade your wireless security protocol to WPA2-AES or WPA3, which are immune to legacy WPS PIN attacks. It scans the local airspace for wireless networks
: Run the WinPcap installer before opening any other tools. Ensure you check the option to start the driver automatically at boot.
JumpStart and Dumpper rely on legacy 32-bit architecture and older Windows API hooks that are frequently blocked or flagged as high-risk threats by modern Windows Defender and third-party antivirus suites. Modern Alternatives for Wireless Auditing
is the library that allows Dumpper and JumpStart to capture raw network traffic and perform low-level packet operations. However, there's a critical piece of information: WinPcap has not been updated since 2013 , and its development has been terminated. The final stable version is 4.0.2, and the last development build is 4.1 beta 4. This means it lacks support for newer Windows versions and has unfixed security vulnerabilities.

Dumpper v.91.2 was primarily developed by Spanish-speaking security communities. It sometimes fails to execute JumpStart paths if there are special characters or structural issues in the folder path.
