Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a simple and effective idea to locate cryptographic functions on the memory for malware analysis.
This leads an analyst to obtain plain-text packets that are encrypted on a secure channel established by malware when she analyzes it on a sandbox environment.
Our idea is to observe a memory area where an encrypted packet is loaded.
Besides, it is also to observe the areas where any pieces of data created from that encrypted packet are loaded. This is based on the fact that although a malware sample can load a sheer number of functions, functions that access to those memory areas de nitely include cryptographic functions.
With experiments using ten cryptographic programs, we extracted 37% of
134{460 functions as candidates on average, and extracted
3% of them at best. In future work, the idea will be expanded for uniquely locating cryptographic functions.
