Running an ARP spoofing tool on a network you do not own or have explicit permission to test is illegal in many jurisdictions. In the United States, it can violate the Computer Fraud and Abuse Act (CFAA) , classified as an unauthorized intentional transmission causing damage to a protected computer.
By 2021, searching for "wifi kill" on GitHub yielded several types of repositories, shifting away from the original Android APK toward open-source cybersecurity education. Python-Based Net-Cutters

: The router instantly drops the connection with the target. Because these frames are unencrypted in older Wi-Fi standards, the target device is repeatedly disconnected as long as the tool runs. The GitHub Landscape in 2021
If you're interested in learning more about WiFi Kill or network security testing in general, here are some additional resources: Running an ARP spoofing tool on a network
: A multi-use bash script for wireless auditing that integrates automated deauthentication scripts.
Remember: Just because you can kill the Wi-Fi doesn’t mean you should. And increasingly, thanks to modern security standards, you simply can’t—unless you’re targeting outdated equipment. Python-Based Net-Cutters This public link is valid for
target_mac = "AA:BB:CC:DD:EE:FF" # Victim's phone router_mac = "11:22:33:44:55:66" # Target Wi-Fi router
: The tool broadcasts a spoofed "deauthentication frame" directly to the wireless router, pretending to be the target device requesting a disconnection.
In the landscape of network security testing, 2021 saw continued interest in tools designed to test the robustness of local wireless networks. Among these, various iterations of found on GitHub—many gaining traction around 2016-2018 and remaining relevant for educational purposes in 2021—were popular for demonstrating ARP spoofing and deauthentication attacks .
