Grey Fox, a former U.S. Air Force member, delivered an engaging talk to a group of enthusiastic Flipper Zero fans at DEFCON 33, a well-known hacking conference. With two decades of expertise in digital network intelligence, cyberspace warfare, and defense strategies, Grey Fox led participants through a practical training exercise demonstrating the Flipper Zero’s abilities. He also introduced some effective social engineering techniques. However, he stressed that this knowledge is intended solely for educational purposes, and using the Flipper Zero to interfere with others’ property is largely forbidden.
What is Flipper Zero?
For those who haven’t heard of the Flipper Zero, it is a user-friendly, open-source device that can be extensively customized. It comes with multiple sensors that allow it to work with various wireless protocols. The Flipper Zero can connect to WiFi, Bluetooth, RF, and NFC to varying degrees. Because of its features, it has developed a reputation as a great starting point for newcomers to wireless hacking while also being useful for seasoned professionals like Grey Fox.
The Training Scenario
In his session, Grey Fox presented a scenario where an intelligence officer had just arrived in a city after receiving intelligence about two dangerous individuals staying at a hotel close to a diplomatic office. Due to a mix-up with their luggage, the officer only has a Flipper Zero and some development boards to collect as much information about the suspects as possible to approve military actions before any attack could take place. Although not perfect, having the Flipper Zero is certainly better than having nothing. Its simplified functions allow the process to be organized into the following steps:
Even though this guidance helps in establishing more confidence in identifying a target, Grey Fox elaborates on how to duplicate hotel keycards and car fobs. Again, it’s important to emphasize that this information is shared strictly for educational reasons. For those interested in learning more, the complete presentation is available below.
