In this final episode of a three-part Bluetooth security series, Adrian Sanabria and Jon Bundy break down practical hacking techniques, covering proximity requirements and specialized hardware needed for attacks. They explore keystroke injection via compromised keyboards, surveillance through headphone microphones, and WhisperPair vulnerabilities that forcibly pair with headsets. The hosts also demonstrate reconnaissance methods and connection hijacking via timing attacks. Their verdict: personal risk is moderate, but enterprises should worry about surveillance and keystroke injection, especially with legacy devices lacking security patches.
