The Ace has returned with yet another Cyber Tech Tool review! Today we look at the Flipper Zero, a portable multi-tool for pentesters and hardware geeks that comes in the form of a tamagotchi. This hardware opens up the world of radio protocols, access control systems, hardware, and more to what was previously a niche security industry. Flipper Zero, on the other hand, is not some magical Watch Dogs-inspired hacking device that will allow you to control traffic lights, security cameras, or ATMs to give you money. It has very limited capabilities and is primarily intended for light pentesting and a gentle introduction to the world of sub-frequencies.
