: It contains built-in libraries for famous WPS PIN algorithms such as ComputePIN, Zhao, Stefan Viehböck's algorithms, and specific vendor algorithms (e.g., D-Link, Belkin, Trendnet).

: Dumpper automated the process of scanning for these vulnerable routers and testing them against a database of known default PINs. Version 40.1: The Community Peak

Dumpper matches the BSSID (MAC address) of the router against known patterns.

: Change default manufacturer passwords to unique phrases containing uppercase letters, lowercase letters, numbers, and symbols.

While Dumpper v401 is an established name in historical network tool catalogs, modern users must approach it with extreme caution due to severe security implications:

The last well-known legitimate versions were in the v3.x range (e.g., v3.5, v3.6). v401 does not appear in official developer documentation or reputable software archives.

If the router has WPS enabled, Dumpper v4.01 can compute or guess the default PIN based on the router’s algorithm (many older routers use predictable PINs). JumpStart then uses this PIN to negotiate a WPS handshake and retrieve the actual Wi-Fi passphrase.

The user initiates a scan to find networks with WPS enabled.
