Dumpper is a portable Windows utility used for auditing wireless network security, specifically by testing vulnerabilities in the WPS (Wi-Fi Protected Setup) protocol. Verified Download
While many unofficial sites host this tool, the most reliable source for verified, malware-scanned versions is SourceForge.
Latest Stable Release: Dumpper v.91.2 is the widely documented version.
Verification: SourceForge scans all hosted files for malware. If you encounter a version labeled v.91.3, ensure it is from a trusted contributor, as it may be a minor community update or a repackaged version. Full Usage Guide
Dumpper typically works in tandem with JumpStart to automate the connection process once a WPS PIN is identified. Preparation:
Download and install the WinPcap or Npcap library if prompted, as Dumpper requires them to capture network packets.
Ensure JumpStart is installed on your system to automate the "pinning" process. Scanning for Networks: Open Dumpper.exe as an administrator. Go to the Wps tab and click Scan.
The tool will list nearby networks. Look for those with a high signal strength and check if they are marked as vulnerable (often highlighted in green). Executing the Audit: Select your target network. Choose the "Start JumpStart" option.
Dumpper will automatically pass the calculated WPS PIN to JumpStart, which will attempt to establish a connection. Retrieving the Key:
If successful, JumpStart will complete the connection. You can then view the Wi-Fi password (WPA/WPA2 key) within the Profiles tab in Dumpper or through Windows' saved network settings. Important Safety & Legal Notes
Permissions: Use this software only on networks you own or have explicit permission to test. Unauthorized access is punishable by law.
Security Risk: Many "verified" download links on third-party blogs contain bundled adware or trojans. Always stick to reputable open-source repositories like SourceForge. dumpper v 913 download verified
Based on technical assessments and security reports, you should avoid downloading "Dumpper v.91.3" from unverified sources. Critical Security Warning
"Dumpper" is an older, third-party utility originally designed for auditing and managing wireless networks (WPS/WPA). Because it is no longer actively maintained by a primary official developer, modern "verified" downloads are frequently used as wrappers for malware Key Findings Malware Risk
: Files labeled "Dumpper v.91.3" on file-sharing sites often trigger high-severity alerts for Trojans and Adware
. These can compromise your system, steal credentials, or install "JumpStart" bundles that contain unwanted software. Obsolescence
: The software relies on outdated vulnerabilities (WPS PIN exploits) that have been patched on almost all modern routers manufactured in the last 10 years. It is highly unlikely to work on current network hardware. Operating System Issues
: Users frequently report that the software causes driver instability or "Blue Screen of Death" (BSOD) errors on Windows 10 and Windows 11 because the required WinPcap drivers are outdated. Rating: 1/5 - Dangerous
Searching for "verified" versions of this tool is a common entry point for phishing and system infection. If you are interested in network security or auditing, it is better to use modern, open-source, and reputable tools that are actively maintained. Better Alternatives
If you are auditing your own network for security vulnerabilities, consider these industry-standard tools: : The world’s foremost network protocol analyzer. Aircrack-ng
: A complete suite of tools to assess WiFi network security. Kali Linux
: A dedicated operating system that comes pre-loaded with legitimate security auditing tools.
Dumpper is a free, portable Windows application designed to manage wireless networks and audit security vulnerabilities. It is widely known for identifying flaws in the WPS (Wi-Fi Protected Setup) protocol. Key Features of Dumpper Dumpper is a portable Windows utility used for
WPS Security Auditing: Analyzes routers for generic or known WPS PINs that may be vulnerable to brute-force or "Pixie-Dust" attacks.
WPA/WPA2 Key Recovery: Attempts to retrieve default network keys based on a router's BSSID and ESSID.
Wireless Management: Provides a centralized interface to scan for available networks and manage local Wi-Fi adapters.
Portable Utility: Runs without installation, typically distributed as a compressed archive (e.g., .rar). Downloading & Verification
Official updates for Dumpper are less frequent, as the software is no longer under active major development. Users typically find it on open-source repositories:
SourceForge: The most common verified host for the project is Dumpper on SourceForge, where files are scanned for known malware.
JumpStart Integration: Dumpper often requires a companion tool called JumpStart to execute the actual WPS pin connection process on older Windows systems. How to Use (Basic Audit)
Scan: Open the application and go to the "Redes" (Networks) tab. Select your Wi-Fi adapter and click Scan to see nearby access points.
Audit WPS: Switch to the "Wps" tab. Select a network to check if it has a vulnerable WPS configuration.
Test Connection: If a vulnerability is found, the tool may suggest a PIN. You can use the integrated JumpStart feature to test if that PIN allows a connection.
Security Warning: This software is intended for educational and authorized security testing only. Unauthorized use against networks you do not own is illegal and unethical.

Dumpper v9.13 remains a valuable tool for legacy wireless audits, especially on networks still relying on vulnerable WPS implementations. However, the emphasis on "download verified" is not paranoia—it's a necessity. The majority of Dumpper downloads on file-sharing sites are backdoored.
Final Verdict:
Remember: A verified download is only as good as the user’s intention. Use Dumpper v9.13 to fix security flaws, not create victims.
Dumpper is a Windows-based utility primarily designed for wireless network auditing. Unlike brute-force hacking tools, Dumpper focuses on protocol weaknesses (specifically WPS – Wi-Fi Protected Setup) and saved credential harvesting.
Originally developed by a well-known security researcher known as "The Wifite" group or "Kocak" (depending on the fork), Dumpper became famous for its ability to:
Version 9.13 is often cited as the "stable classic"—balancing functionality without the bloatware or telemetry found in newer, unverified releases.
Using Dumpper v9.13 to access a Wi-Fi network without explicit permission is illegal in most jurisdictions under computer fraud laws (CFAA in the US, Computer Misuse Act in the UK). The tool has legitimate uses only for:
