- The Flipper Zero device caused quite a stir among iPhone users in September
- With slightly modified software, it could be used to completely paralyze a foreign iPhone
- Apple prevented the abuse of this device as part of the iOS 17.2 update
Three months ago, we informed you about a curious bug hidden in the iPhone, which could be exploited with the help of a smart box for several thousand. That device is called Flipper Zero and it is commonly available at a price of approximately 4 thousand crowns. If an attacker misused it, they could completely paralyze your device. Although it was a rather unlikely possibility, the Californian giant decided to play it safe and release an update to prevent such an attack, should someone actually want to carry it out.
Flipper Zero is no longer a threat to the iPhone
As pointed out by the server ZDNet, Apple has finally implemented safeguards in iOS 17.2 to prevent Flipper Zero devices from sending nearby iPhones and iPads into endless denial-of-service (DoS) loops. At its core, the Flipper Zero is a fairly innocuous testing device. However, since this is an open-source device, it can be modified with third-party firmware (Xtreme in this case) that provides Bluetooth Low Energy (BLE) spamming.
Using a bug in the BLE pairing sequence, an app can send an overwhelming amount of Bluetooth connection notifications to nearby devices, causing them to freeze and reboot. This process takes about five minutes, but to an unsuspecting victim it can feel like an eternity. Thanks to a radio range of approximately 50 meters, modified Flipper Zero devices can be used for unobserved DoS attacks in trains, cafes and or at concerts.
Don’t overlook
The iPhone has a curious bug. With a box for 4 thousand you will perform a DDoS attack on him
What are the likely new security features of iOS 17.2? While running Flipper Zero with modified DoS attack software, there are still some annoying pop-ups, but after a while this stops. This could be the new ad packet request timeout that Apple has implemented. However, we will probably never know the exact type of iPhone protection against a similar type of attack. In any case, the positive thing is that you no longer have to worry about this attack.
