The “Power Grid” is a growing topic in the security industry and Advanced Metering Infrastructure (AMI) is a topic that hasn’t been discussed to its full potential. This presentation will discuss the types of vulnerabilities that have been found in Smart Meters, and give examples from real world assessments we’ve conducted. Different methods of accessing the meter will be presented such as over the optical interface and the Zigbee wireless radio. In addition, we will discuss a testing methodology we’ve developed which covers Smart Meter testing. Finally a live demonstration of the attacks that were discussed will be performed on a real Smart Meter during the presentation for the audience.
