The vulnerability Instrumenting the card What information can we retrieve from the card? Specifications and experiments say we have access to: ◮ RX RISC mode register; ◮ RX RISC state register; ◮ RX RISC program counter; ◮ RX RISC hardware breakpoint register; ◮ some general registers. We can use this knowledge to build that debugger. SGDSN/ANSSI – http://www.ssi.gouv.fr/trustnetworkcard 30/51
The vulnerability Instrumenting the card Our homemade debugger: ◮ uses information from mapped registers; ◮ runs in step-by-step mode; ◮ can perform register/memory tracking; ◮ can break on register/memory access; ◮ can do some pattern matching.
