SIM card and handset forensics
David Naccache, ENS, France
Abstract
In this talk we will describe the methodology used for Mobile Equipment Forensic analyses within the French legal context. We will describe specific technical problems applicable to the analysis of cards ( e.g. the impossibility to interact with a SIM without altering its internal state), underline seizure details, demonstrate the tools allowing to extract the contents of a SIM knowing its associated PIN codes.
We will overview the "heavy" analysis methods (physical reverse-engineering and fault-based) developed and used for secure chip evaluation when PIN codes are unknown and illustrate a protocol allowing to negotiate with the judiciary authorities an evidence destruction risk before undertaking the actual analysis of the SIMs and handsets.
