报告简介
In this talk, we begin with an introduction to Execution Flow Instrumentation (EFI), a powerful dynamic analysis approach that interleaves the instruction flows of the target thread and of the analysis thread together without mixing up their code. EFI thus combines the advantages of code instrumentation and hardware-aided event trapping but without their drawbacks. We then present OASIS which is a system infrastructure that realizes EFI. On top of OASIS, a user can run her user-space analyzer to conduct dynamic analysis upon a kernel- or user- thread running in a guest virtual machine with guaranteed security and transparency. Applications of OASIS based EFI go beyond conventional dynamic analysis. It allows us to build a kernel symbolic execution engine (named as KRover) without involving intermediary representation or dynamic binary translation. It can also be applied in cloud platforms to introspect and repair malfunctioning virtual machine.
