The findings relate to the improper implementation of Google's Fast Pair protocol, which enables one-tap pairing and account synchronization across Bluetooth accessories. If the protocol hasn't been implemented correctly, a security flaw is introduced that "allows an attacker to hijack devices and track victims using Google's Find Hub network," according to the researchers.

A 150-day disclosure window was agreed and a bug bounty of $15,000 was awarded. WhisperPair occurs because many audio accessories skip a "critical step" during Fast Pair pairing. This is how it works: a "seeker" -- such as a Bluetooth-enabled mobile device -- sends a message to the "provider," an audio accessory. The message includes a pairing request.
