Security researchers have identified a novel exploitation vector targeting iPhone devices through the Flipper Zero hacking tool. The approach leverages spoofed Bluetooth signals to imitate Apple devices such as AirTag, Apple TV, and AirPods, effectively triggering intrusive pop-up messages on the victim’s smartphone. The finding has been reported by TechCrunch within its coverage of the incident.
The researcher, known in the community as Anthony, described the method as Bluetooth Ad Attack, a name that in Russian translates to Bluetooth attack via advertising messages. He documented the experiment on his blog, detailing how the attack not only disrupts normal iPhone operation but also undermines user peace of mind by generating an endless series of unwanted pop-up notifications that seem impossible to dismiss. These pops appear as prompts to connect to non-existent AirPods, creating confusion and concern for the user. TechCrunch reporters observed the same behavior during their assessment, providing a corroborative account of the attack’s impact.
In the reported tests, the flaw was enabled by modifying the Flipper Zero firmware to emit signals that Apple devices routinely scan for to establish mutual recognition. By broadcasting these signals, the tool can simulate the presence of the listed peripherals, prompting the iPhone to surface connection prompts and notifications even when those devices are not nearby. This effect was demonstrated with devices including an iPhone 8 and an iPhone 14 Pro, according to the observers who loaded Anthony’s code and activated Bluetooth to verify the outcome. The resulting notifications urged the user to connect to hypothetical AirPods, illustrating how the tactic can cloak itself as a legitimate pairing prompt and thereby sow confusion. The vulnerability persisted even if Bluetooth was turned off via the Control Center, though it did not succeed when Bluetooth was completely disabled through iPhone settings. These nuances underscore the importance of how OS-level and hardware-level Bluetooth controls interact with third party hardware signals in real world scenarios.
Anthony indicated that with access to a more capable hardware board, the reach of the attack could extend over larger distances, potentially increasing its scope and ease of deployment. He also cautioned that sharing specific details of the enhanced method could enable misuse, underscoring the tension between disclosure and risk in security research. The disclosure pattern mirrors common debates in the security community about how much detail is appropriate when a vulnerability exists, especially when it could be exploited by malicious actors. The discussion highlights the need for robust defensive measures from device makers and operating system developers to mitigate similar spoofing techniques in the future.
Apple has not issued an official statement about this particular exploitation vector at this time, leaving the community to interpret the potential implications and response strategies. The absence of immediate commentary from the company heightens the sense of urgency around evaluating device defenses and user practices that can reduce exposure to such spoofing attempts. In the broader landscape, this incident adds to a growing list of concerns about how consumer devices can be manipulated through seemingly legitimate communications channels like Bluetooth advertising messages.
Earlier reports from various public agencies mentioned restrictions related to using consumer smartphones in official settings, which in some cases included limitations on bringing personal devices into certain work environments. While these advisories are not direct responses to the Bluetooth Ad Attack, they reflect a broader context in which organizations weigh the balance between connectivity benefits and security risks. Users are advised to stay informed about firmware updates, Bluetooth controls, and official guidance from device makers to maintain safer device experiences during everyday use.
