Flipper Zero

The Flipper Zero is a small, open-source hardware device that can be used to interact with a variety of wireless devices. It can be used to send and receive Bluetooth, Wi-Fi, and RFID signals.

The Flipper Zero can be used to spam iPhone users with Bluetooth pop-ups by imitating devices like AirPods, AppleTV, and AirTags. This is done by sending a continuous stream of Bluetooth advertisements that appear to come from these devices. When the iPhone receives these advertisements, it displays a pop-up notification asking the user if they want to connect to the device.

The Flipper Zero can also be used to send Bluetooth advertisements that contain malicious code. This code could be used to steal data from the iPhone or to install malware on the device. Hackers use the Flipper Zero to spam iPhone users with Bluetooth pop-ups by exploiting a vulnerability in the way that Apple devices handle Bluetooth advertisements even when the device is not actually available to connect.

Bluetooth advertisements are short messages that devices broadcast to let other devices know that they are available to connect. When an iPhone receives a Bluetooth advertisement, it displays a pop-up notification asking the user if they want to connect to the device. This can cause the iPhone to display a constant stream of pop-up notifications, which can be very annoying and disruptive.

This can also trick the iPhone into thinking that the device is a trusted device, and the user may be more likely to accept the connection request. A blog post on GitHub by ‘Techryptic’ suggests Flipper Zero can be programmed to carry out wireless attacks not only on iPhones, but can also target other devices like RFID cards and smart car keys.

To protect yourself from this attack, you can:

· Keep your iPhone's software up to date. Apple has released security updates that address the vulnerability that is exploited by this attack.

· Disable Bluetooth when you are not using it. This will prevent the Flipper Zero from being able to send Bluetooth advertisements to your iPhone.

· Be careful about what devices you connect to your iPhone. Only connect to devices that you trust.

If you receive constant stream of Bluetooth pop-up notifications, it is possible that you are being targeted by this attack. You should disconnect from any Bluetooth devices that you are connected to and then restart your iPhone.
