In a recent revelation, Flipper Zero Devices have been found to possess the ability to launch Denial of Service (DoS) attacks on iPhones. This discovery has raised concerns about the security of Apple devices, particularly when it comes to potential threats and vulnerabilities. In this article, we delve into the details of this alarming development and the implications it carries for iPhone users.
Understanding the Flipper Zero Attack
Threat actors have identified a novel way to disrupt the functionality of iPhones by employing Flipper Zero Devices. These devices can inundate iPhones with a barrage of pop-up notifications, typically pertaining to nearby AirTag, Apple TV, AirPods, and other Apple devices. This bombardment of pop-ups not only causes significant annoyance to users but also poses a serious security risk.
Wireless Attacks and Their Targets
What makes Flipper Zero Devices even more menacing is their capability to execute wireless attacks targeting various devices. These include car keyfobs, RFID cards, iPhones, and potentially many more. Security researcher Anthony, who stumbled upon this vulnerability, has termed it as a “Bluetooth advertising assault.”
Flipper Zero and Bluetooth Advertising
The Flipper Zero firmware is at the heart of this exploit, enabling what is known as “Bluetooth Advertising.” This is a form of transmission within the Bluetooth Low Energy protocol, specifically employed by Apple to facilitate connections between iDevices and other Apple products. It serves as the foundation for functions like sending pictures via the Bluetooth file sharing system, AirDrop.
Demonstrated Vulnerabilities
TechCrunch conducted experiments to validate these vulnerabilities, successfully replicating them on both the iPhone 8 and the recently released iPhone 14 Pro models. This alarming discovery indicates that attackers could potentially leverage these vulnerabilities to their advantage. It’s essential to note that this was achieved by modifying the Flipper Zero firmware with custom code. The simple act of enabling Bluetooth on Flipper Zero initiates the broadcasting of pop-up signals to nearby iPhones.
Bluetooth State and Vulnerabilities
Interestingly, the exploits were effective on iPhones regardless of whether Bluetooth was enabled or switched off via the Control Center. However, it’s worth mentioning that the researchers could not reproduce the exploit when Bluetooth was entirely disabled from the iPhone’s settings.
Extended Reach and Millions of Devices
Furthermore, Anthony revealed the ability to create attacks with an extended reach, spanning even miles, and generating pop-ups on numerous devices simultaneously. However, the researcher has chosen not to disclose further details about this attack method, as doing so could significantly increase the threat surface for potential attackers.
Mitigation and Research
In response to this alarming revelation, Anthony has published a comprehensive exploit and research findings, shedding more light on the Denial of Service (DoS) attack. He suggests that Apple could mitigate this issue by implementing measures to verify the integrity of Bluetooth devices connecting to iPhones. Additionally, limiting the distance at which iDevices can connect to other Bluetooth-enabled devices could enhance security.
Conclusion
The discovery of Flipper Zero Devices’ capability to perform Denial of Service attacks on iPhones highlights the ever-evolving landscape of cybersecurity threats. It serves as a stark reminder of the importance of vigilance and proactive measures to safeguard personal data and device security.
