ARP Spoofing is a basic and core hacking technology for almost all sniffing. It makes change the flow of packets by faking the 2nd layer MAC address. In this paper we suggested an efficient hacking technology for sniffing remote servers in the switched network environment. The suggested 'Faked ARP Reply Unicast Spoofing' makes the bidirectional packets sniffing possible between the client and server, and it makes simplify the procedures for ARP sniffing and hacking program. In this paper we researched the network hacking and implementation technologies based on the suggested ARP spoofing. And we researched various types of servers hacking such as Root ID and PW of Telnet/FTP server, Root ID and PW of MySQL DB server, ID and PW of Web Portal Server, and account information and transaction history of Web Banking Server. And also we researched the implementation techniques of core hacking programs for the ARP Spoofing.

Switched Network는 Shared Network 에 비해서 스니핑에 안전하다. 하지만 비교우위일뿐 절대적으로 스니핑에 안전한 것은 아니다. 이미 Switched Network 상에서 스니핑을 할 수 있는 공격툴들이 많이 소개되어 있다. 본 논문에서는 Switched Network 상에서 ARP(Address Resolution Protocol) 스푸핑을 통한 ARP 캐시 오염을 통하여 스니핑이 가능한 시나리오를 기술한다. 이러한 시나리오를 탐지하기 위한 기존의 방법은 DHCP와 같은 동적인 환경이 포함된 경우 False Positive 를 자주 발생시키기 때문에 문제가 된다. 여기에서는 이러한 False Positive를 줄인 탐지 방법을 제시하고자 한다.

Is need Remote Access through internet for business of Ubiquitous Computing age, and apply OTP for confidentiality about inputed ID and Password, network security of integrity. Current OTP must be possessing hardware or Token, and there is limitation in security. Install a Snooping tool to OTP network in this treatise, and because using Cain, enforce ARP Cache Poisoning attack and confirm limitation by Snooping about user password. Wish to propose new system that can apply Tokenless OTP by new security way, and secure confidentiality and integrity. Do test for access control inflecting Tokenless OTP at Remote Access from outside. and could worm and do interface control with certification system in hundred. Even if encounter hacking at certification process, thing that connection is impossible without pin number that only user knows confirmed. Because becoming defense about outward flow and misuse and hacking of password when apply this result Tokenless OTP, solidify security, and evaluated by security system that heighten safety.
