is a portable, open-source tool for Windows designed to audit the security of wireless networks. It primarily focuses on identifying vulnerabilities in the WPS (Wi-Fi Protected Setup) protocol.

: Uses default Windows wireless APIs to interact with your network interface card (NIC).

, a tool that automates the process of connecting to a Wi-Fi network once a vulnerable WPS PIN is identified. Network Scanning

: The entire utility runs from a self-contained executable file, which means it requires zero installation or modification of Windows registry keys.

The most prominent feature is its ability to scan for wireless networks that have WPS enabled

It is natively designed for Windows (XP through 10).

: Log into your router’s admin panel (usually via 192.168.1.1 or 192.168.0.1 ) and completely turn off WPS.

: View detailed information about nearby access points, including BSSID, ESSID, signal strength, and encryption type.

is a Windows-based utility designed for wireless network assessment, specifically targeting WPS (Wi-Fi Protected Setup) vulnerabilities. Developed by the Spanish security researcher Javier Suárez (Kraken) , Dumpper is widely recognized as a companion tool to JumpStart (for auditing) and WPS Pin Generator (for key calculation). Version 90.6 is a stable, feature-rich release focused on WPS brute-force protection analysis and default PIN generation for a wide range of router models.

Dumpper includes several language packs, making it accessible to a global user base. How It Works: The WPS Method

: It provides a detailed view of nearby wireless networks, displaying information such as SSID, MAC address, signal strength, and encryption type (WPA, WPA2, etc.). Update Management

Dumpper v.90.6 remains a notable example of network security auditing software from the late 2010s. While its methodology highlights the significant risks posed by the WPS protocol and default router configurations, its practical utility is limited to outdated hardware that has not been patched against these well-known vulnerabilities. For users interested in cybersecurity, Dumpper serves more as an educational tool to demonstrate the importance of changing default router settings and disabling legacy protocols like WPS, rather than as a reliable solution for password recovery.

Administrators use Dumpper v.90.6 alongside JumpStart to run safety audits on internal company or home networks using the following workflow: Download Dumpper v.91.2.rar (Dumpper)
