Mar 1, 2024 · A Beacon is a small, wireless, one-way hardware transmitter that uses Bluetooth Low Energy (BLE) 4.2/5.0/5.2 protocols to transmit a unique identifier along with any other signal (data) to nearby Bluetooth-enabled devices.
Beaconing is a form of communication between a compromised computer and a remote command and control (C&C) server. In simpler terms, it is a signal sent out by an infected device to a cybercriminal’s server indicating that the device is still active and ready to receive commands.
Beacons are low-cost, wireless transmitters that use Bluetooth Low Energy technology to transmit proximity-based signals to other devices nearby. The use of less energy ensures a twice longer battery span and allows the use of Beacons for longer periods.

The Beacon Protocol is a communication framework designed to facilitate the exchange of signals and messages between devices, particularly in wireless networks. This protocol is critical in enabling devices to discover, connect, and maintain communication within a network, ensuring efficient and reliable data transmission.
Feb 8, 2021 · Every system is a little different, but here’s how a beacon communicates, in a nutshell: The beacon sends out its ID numbers about ten times every second (sometimes more, sometimes less, depending on its settings). A nearby Bluetooth-enabled device, like your phone, picks up that signal.
What is C&C Beaconing? Command-and-control (C&C or C2) beaconing is a type of malicious communication between a C&C server and malware on an infected host. C&C servers can orchestrate a variety of nefarious acts, from denial of service (DoS) attacks to ransomware to data exfiltration.
