ABSTRACT:

Security is typically an afterthought but not considered during the initial system design. As a result, many systems were designed with good intention but are insecure: tire pressure monitoring systems (TPMS) were intended to improve road safety and fuel economy; automatic metering reading (AMR) systems were designed to reduce the burden of manually collecting utility consumption; and implantable medical devices (such as pacemakers) were designed to help patients to cope with diseases. However, the security of those systems is not well understood as many of their protocols are proprietary. In this talk, we present case studies analyzing the first mandated in-car sensor networks (TPMS), widely deployed AMR utility meters, commonly used microphones, and even pacemakers, using a low-cost out-of-shelf software radio platform (USRP). We show that all these systems are vulnerable to attacks that range from wireless eavesdropping to RF interference injection. This leads to privacy concerns as vehicles can be tracked through the identifiers of TPMS or residents’ activities can be recognized through the periodic meter reading reports. In addition, these systems do not employ authentication or basic input validation, thereby allowing for remote spoofing of sensor manipulation. The talk concludes with a set of recommendations for improving the privacy and security of tire pressure monitoring systems, ARM utility meters, and other forthcoming consumer wireless networks.
