Bluetooth PHYs and Ranges – Part 1

Excerpt From Bluetooth Vulnerabilities (Part 1) Webinar
Watch CTO Dr. Brett Walkenhorst on Bluetooth PHYs and Ranges
It’s easy to picture the relatively short range for a connection between two personal devices like a cellphone and a headset and come to the conclusion that Bluetooth only works over these kinds of very short distances. However, as Brett described in this video, Bluetooth can actually work over significant distances. He shares examples of organizations that were able to amplify the connectivity range even as much as 5x the average expected range. This has security implications due to the fact that Bluetooth related attacks do no necessarily need to be actioned by a malicious actor who is in close range.
