Recent Flipper Zero Bluetooth spam attacks have now been ported to an Android app, allowing a much larger number of devices to implement these annoying spam alerts. Inspired by previous research on the topic and Flipper Zero applets targeting iOS devices, and later Android and Windows, software developer Simon Dankelmann developed an Android app capable of the same Bluetooth spam.
A custom Flipper Zero firmware called 'Xtreme' has added a new feature to perform Bluetooth spam attacks on Android and Windows devices. The main idea behind the spam attack is to use Flipper Zero's wireless communication capabilities to spoof advertising packets and transmit them to devices in range of pairing and connection requests.
