Abstract(in Japanese) (See Japanese page)
Abstract(in English) Malware executables are often obfuscated with encryption or compression using a technique known as packing, thus performing static analysis on such executables requires a preprocessing called unpacking. In this paper, we propose an automatic unpacking method that infers the behaviour of a packed program by analyzing the temporal change in the entropy values of buffers filled with values actually read or written to memory by the program. We also show the effectiveness of our method through experiments.
