This chapter describes several vulnerabilities that affect commercial and residential Bluetooth Low Energy security devices and outlines methods for exploiting plaintext, obfuscated and hard-coded passwords, brute forcing passwords and hashes, fuzzing commands and performing man-in-the-middle attacks. Evaluations reveal that 75% of the tested security and access control systems have vulnerabilities that grant unauthorized access. In addition to obtaining access, malicious actors can extract sensitive information that can be used to develop patterns of human behavior. This chapter discusses five solutions for preventing or mitigating Bluetooth Low Energy security breaches, most of which involve minimal implementation overhead on the part of developers.
