Jeroen van der Ham
One morning two weeks in the past, safety researcher Jeroen van der Ham was touring by practice within the Netherlands when his iPhone abruptly displayed a sequence of pop-up home windows that made it practically unattainable to make use of his system.
“My telephone was getting these popups each jiffy after which my telephone would reboot,” he wrote to Ars in an internet interview. “I attempted placing it in lock down mode, however it did not assist.”
To van der Ham’s shock and chagrin, the identical debilitating stream of pop-ups hit once more on the afternoon commute dwelling, not simply towards his iPhone however the iPhones of different passengers in the identical practice automobile. He then observed that one of many similar passengers close by had additionally been current that morning. Van der Ham put two and two collectively and fingered the passenger because the perpetrator.
“He was blithely engaged on some sort of app on his Macbook, had his iPhone out himself, linked by USB so he may nonetheless work whereas throughout him apple gadgets have been rebooting and he was not even being attentive to what was occurring,” he mentioned. “Your telephone turns into nearly unusable. You possibly can nonetheless do stuff in between for a few minutes, so it is actually annoying to expertise. At the same time as a safety researcher who had heard about this assault, it is actually onerous to understand that that’s what’s occurring.”
“The jig is up”
The perpetrator, it turned out, was utilizing a Flipper Zero system to ship Bluetooth pairing requests to all iPhones inside radio vary. This slim, light-weight system has been accessible since 2020, however in latest months, it has develop into far more seen. It acts as a Swiss Military knife for every kind of wi-fi communications. It could work together with radio alerts, together with RFID, NFC, Bluetooth, Wi-Fi, or normal radio. Individuals can use it to covertly change the channels of a TV at a bar, clone some lodge key playing cards, learn the RFID chip implanted in pets, open and shut some storage doorways, and disrupt the traditional use of iPhones.
These kinds of hacks have been doable for many years, however they require particular tools and a good quantity of experience. The capabilities usually required costly SDRs—quick for software-defined radios—that, in contrast to conventional hardware-defined radios, use firmware and processors to digitally re-create radio sign transmissions and receptions. The $200 Flipper Zero is not an SDR in its personal proper, however as a software-controlled radio, it could do most of the similar issues at an inexpensive worth and with a type issue that’s far more handy than the earlier generations of SDRs.
“The jig is up: software program radios have made beforehand inaccessible assaults accessible to many extra folks than earlier than, and work on them will proceed,” Dan Guido, CEO of safety agency Path of Bits, wrote in an interview. “People who find themselves casually involved in expertise can now simply clone most lodge or workplace keycards. They do not want any information of alerts or should mess with open supply code or Linux. [It] undoubtedly democratizes some previously advanced RF [radio frequency] hacking into the arms of mere mortals.”
The Flipper Zero producer payments the system as a “moveable multi-tool for pentesters and geeks” that’s appropriate for hacking radio protocols and constructing entry management methods, troubleshooting {hardware}, cloning digital key playing cards and RFID playing cards, and to be used as a common TV distant. Its open supply design permits customers to flash the system with customized firmware to tackle new capabilities.
A few of the specs for the system embody:
- 1.4-inch monochrome LCD show
- GPIO pins for connecting exterior {hardware} that tremendously expands its capabilities
- USB-C port for energy and firmware updating
- micro SD card slot
- Infrared transceiver
- Sub-1 GHz antenna
- TI CC1101 chip
- 1-Wire pogo pin for studying contact keys
- 2000 mAh battery
- Low energy MCU
- ARM Cortex-M4 32-bit 64 MHz (software processor)
- ARM Cortex-M0+ 32-bit 32 MHz (radio processor)

“The concept of Flipper Zero is to mix all of the {hardware} instruments you’d want for exploration and growth on the go,” the producer wrote. “Flipper was impressed by pwnagotchi undertaking, however in contrast to different DIY boards, Flipper is designed with the comfort of on a regular basis utilization in thoughts—it has a strong case, helpful buttons, and form, so there aren’t any soiled PCBs or scratchy pins.”
