An electronic pet that can hack Wi-Fi?

Pwnagotchi is an electronic pet kit that collects information via security researcher Simone Margaritelli and white hacker hexwaxwing and WiFi vulnerabilities. It contains a single-board computer Raspberry Pi Zero W, which is about the size of a palm and equipped with Wi-Fi and Bluetooth, and expresses emotions and sorrows with ASCII art icons while searching for nearby Wi-Fi information.

Wi-Fi technology standards WPA and WPA2 perform a 4-way handshake by sharing and authenticating information between a client and an access point, and generating a symmetric key for encryption. However, a vulnerability exists that allows third parties who do not know the WPA and WPA2 passwords to access the Wi-Fi network by blocking the 4-way handshake.

Funagochi is a software that can efficiently find Wi-Fi and store information through deep reinforcement learning algorithms like those used in AlphaGo. All you need to carry Funagotchi is a Raspberry Pi Zero W, a microSD card with a capacity of 8GB or more, an external battery, and a 2-inch e-ink display.

The body displays faces or text through a palm-sized e-ink display. The displayed face may vary depending on the result of the Wi-Fi hack. Funagochi’s emotions include kindness, boredom, happiness, and loneliness, and he mutters lines depending on the result of the Wi-Fi hack. Not only that, but if another Punagochi is physically close, they can exchange information with each other. It is said that communicating with each other affects the mood of Punagochi and may cultivate friendship.

Punagochi is a combination of the hacking term Pwn and Tamagotchi, which was popular in the 90s. The official website of Punagochi explains that you will be able to feel the nostalgia of the 90s that had strange feelings on mobile devices. He said he was concentrating on the fact that when you add facial expressions to gadgets, people become obsessed with gadgets.

Punagochi is not a specialized hacking tool, and DDoS attacks are restricted so that it cannot be performed. Funagochi is a learning tool for anyone interested in hacking. Its main purpose is to educate users to learn and enjoy safe Wi-Fi technology. Punagochi software is also available on GitHub. Related information can be found here .
