Abstract: Disclosed herein are an apparatus and method for detecting violation of control flow integrity. The apparatus includes memory for storing a program and a processor for executing the program, wherein the processor multiple branch identifier registers to which identifiers of branch targets are written, a set branch identifier instruction configured to command an identifier of a branch target to be written to a branch identifier register at a predetermined sequence number, among the multiple branch identifier registers, and a check branch identifier instruction configured to command a signal indicating detection of a control flow hijacking attack to be issued based on whether a value written to the branch identifier register at the predetermined sequence number is identical to a value of an identifier of a branch target at the predetermined sequence number, wherein the program detects whether a control flow is hijacked based on the multiple branch identifier registers.

Abstract: Disclosed herein are an apparatus for analyzing non-informative firmware and a method using the apparatus. The method includes detecting a target instruction for firmware analysis in a memory map in non-informative firmware, generating an analysis list based on memory map information corresponding to the target instruction, and generating a visualized analysis result corresponding to the firmware by grouping the entries of the analysis list by preset reference bytes.

Abstract: Disclosed herein are an Artificial Intelligence (AI)-based automated method for restoring a mask Read-Only Memory (ROM) firmware binary and an apparatus for the same. The AI-based automated method is performed by an AI-based automated apparatus for restoring a mask ROM firmware binary, and includes generating a bit-order list by inputting bit information and a parameter that are input for restoration to a pre-trained generation model, and restoring a firmware binary based on the bit-order list.
