A security researcher says that a Flipper Zero device can carry out DoS attacks on iPhones running iOS 17 by continuously sending Bluetooth pairing requests
No cure yet for a popular iPhone attack, except for turning off Bluetooth. — One morning two weeks ago, security researcher Jeroen van der Ham …
Context & Ripple Effects
This report documents a nearby wireless disruption route against iOS 17 devices at a time when Apple’s device-adjacent protocols had already drawn scrutiny, including a previously patched AWDL zero-click iOS exploit. The practical significance is its low-friction trigger: affected users’ only stated workaround was to disable Bluetooth.
The issue was subsequently closed in iOS 17.2’s Flipper Zero DoS fix, making this a concise example of public research surfacing a consumer-device reliability flaw and driving a platform patch.
First-order effects
- iPhone users running the affected iOS 17 versions can have normal Bluetooth use disrupted by repeated nearby pairing prompts; disabling Bluetooth removes the reported exposure.
- Apple must remediate the pairing-request handling path, while Flipper Zero becomes a readily available tool associated with demonstrating the weakness.
Second-order effects
- The later iOS 17.2 fix cuts off this specific attack route, shifting the immediate burden from user workarounds to software-update adoption.
- The finding heightens attention on Bluetooth’s authentication and pairing flows, especially alongside a separate Bluetooth authentication flaw affecting command input on multiple platforms.
Third-order effects
- If repeated research findings continue to emerge around short-range radios, consumer platforms will face greater pressure to treat wireless discovery and pairing as availability-security boundaries, not just convenience features.
- The pattern favors faster platform-level patching over relying on users to disable radios, though the corpus does not establish whether this incident changes broader Bluetooth standards or device design.
The trend: This is one data point in the wider hardening of always-on, short-range wireless interfaces as inexpensive tools make reliability attacks easier to demonstrate.
