Crashing iPhones with a Flipper Zero
The Flipper Zero is an incredibly versatile hacking device. Now it can be used to crash iPhones in its vicinity by sending them a never-ending stream of pop-ups.
These types of hacks have been possible for decades, but they require special equipment and a fair amount of expertise. The capabilities generally required expensive SDRs—short for software-defined radios—that, unlike traditional hardware-defined radios, use firmware and processors to digitally re-create radio signal transmissions and receptions. The $200 Flipper Zero isn’t an SDR in its own right, but as a software-controlled radio, it can do many of the same things at an affordable price and with a form factor that’s much more convenient than the previous generations of SDRs.
