Dumpper is a portable, free software tool for Windows used to manage wireless networks and test for security vulnerabilities in the WPS (Wi-Fi Protected Setup) protocol.
While you specifically asked for version 91.4, current official archives and repositories primarily host and document version 91.2. It is important to note that this tool is often flagged by antivirus software as a "Suspicious Sample" or "Hacktool" because its primary function—recovering default WPA/WPA2 keys—is frequently used for unauthorized network access. Core Functionalities
WPS Security Auditing: Checks if a router uses a known or generic WPS PIN that is vulnerable to brute-force or Pixie-Dust attacks.
WPA/WPA2 Key Recovery: Attempts to obtain default network keys based on a router's BSSID and ESSID.
Network Management: Provides a simplified interface for viewing and connecting to nearby wireless networks on Windows. Trusted Sources & Documentation
Because this software is "grey-area" security tool, you should only download it from established open-source repositories to avoid malware.
Official Repository: You can find the archived versions and community updates on the Dumpper SourceForge Page.
Related Tools: Dumpper is often used alongside JumpStart, another utility required for the WPS pin-connection process.
Waircut: For more modern WPS auditing, developers often recommend Waircut (Wireless Air Cut), which is actively maintained and serves a similar purpose. Security Warning
Use of Dumpper and similar tools should be limited to educational purposes or testing your own hardware. Running these programs often requires you to disable Windows Defender or other security suites, which increases the risk of infection if the file is sourced from an unofficial site.
