Unveiling New Attack Vectors in Bluetooth Vulnerability Discovery through Protocol State Machine
Black Hat Asia 2025 · Day 1 · Briefings
This talk, presented by Leong, Wa, and Oliver Dong from SRAD, introduces a groundbreaking methodology for discovering Bluetooth vulnerabilities by deconstructing and manipulating the underlying protocol state machines. Moving beyond the limitations of traditional fuzzing techniques, the researchers demonstrate how intentionally disrupting the expected flow of Bluetooth messages can uncover deep-seated, high-impact security flaws. The presentation highlights the critical shift in vulnerability discovery, emphasizing that modern Bluetooth stacks are resilient to simple packet mutations, necessitating a more sophisticated approach focused on state transitions and inter-protocol interactions.
