Billions of smartphones, tablets, laptops, and IoT devices are using Bluetooth software stacks that are vulnerable to a new security flaw disclosed over the summer.
Named BLESA (Bluetooth Low Energy Spoofing Attack), the vulnerability impacts devices running the Bluetooth Low Energy (BLE) protocol.
BLE is a slimmer version of the original Bluetooth (Classic) standard but designed to conserve battery power while keeping Bluetooth connections alive as long as possible.
Due to its battery-saving features, BLE has been massively adopted over the past decade, becoming a near-ubiquitous technology across almost all battery-powered devices.
As a result of this broad adoption, security researchers and academics have also repeatedly probed BLE for security flaws across the years, often finding major issues.
