Shellcodes are essential parts of remote exploit, and display wide range of varieties (polymorphism). Many researchers have focused on algorithm that enables us to detect shellcodes with polymorphic feature. Though many algorithms for shellcode detection have been proposed, none has been proved to be implemented into hardware and to perform Gbps throughput. We have implemented our shellcode det...
Shellcodes are small assembly programs used in remote exploits. Some researchers focus on shellcode analysis and detection of shellcodes, but they failed to build a shellcode detection system with enough precision and performance. In this paper, we show our method of analyzing and detecting shellocdes over network traffic, and demonstrate our shellcode-detecting system. At first, we briefly def...

In order to develop an accurate automatic differential diagnostic system with statistical methods, a large amount of data from patient interviews is required. On the other hand, many Internet users often supply their own information to the public.Our hypothesis is that the medical data collected from general Internet users is useful to develop an automatic statistical diagnostic system. The pur...
