Damage is increasing by (Smishing) hacking attack Smishing you use a smart phone after entering 2013. Takeover of personal information and direct financial damage in collaboration with graphics sewing machine hacking attack has occurred. Monetary damage that leads to Internet payment service (ISP) and secure payment system in conjunction with graphics sewing machine hacking attack on a smartphone has occurred. In this paper, I will study analysis in the laboratory examples of actual infringement vinegar sewing machine hacking attack. It is a major power security measures to prevent damage to the secure payment system that a case analysis and practical principle technical nest sewing machine hacking attack, using Smishing. In this paper, I will be to research to be able to through a smart phone, to the online payment safer and more convenient.

The recent trend of cyber attack threat is mainly APT (Advanced Persistent Threat) attack. This attack is a combination of hacking techniques to try to steal important information assets of a corporation or individual, and social engineering hacking techniques aimed at human psychological factors. Spear phishing attacks, one of the most commonly used APT hacking techniques, are known to be easy to use and powerful hacking techniques, with more than 90% of the attacks being a key component of APT hacking attacks. The existing research for cyber security threat defense is mainly focused on the technical and policy aspects. However, in order to preemptively respond to intelligent hacking attacks, it is necessary to study different aspects from the viewpoint of social engineering. In this study, we analyze the correlation between human personality type (DISC) and cyber security threats, focusing on spear phishing attacks, and present countermeasures against security threats from a new perspective breaking existing frameworks.

Hacking damage is increasing year by year in the Internet payment service credit card applying the digital signature method of PKI-based first domestic, secure payment, was 180 million won in 2012. Revenues have soared for phishing that Smishing using smartphone after entering 2013. Hacking accident to the secure payment system using Smishing has occurred took over personal information and financial direct damage. In this paper, we analyzed for Smishing, to prevent the damage of secure payment using Smishing to study the hacking attack of secure payment. In addition, it would be studies to allow through the smartphone, online payment safer and more convenient.

With the development of computer technology, and have diversified technical system attacks evolve more. Computer hardware and software has evolved more and more, performance is improved, but the basic principle of operation does not change much, it is a problem. In general, the application is placed in a running state, the program data is placed in memory. Remains in memory for efficiency of operation of the operating system, we analyze memory and memory hacking, these data will have access to data. Since a large damage occurs key, such as certificates personal information, encrypted flows out, measures should be provided by it. In this content, I want to discuss the issues and work around memory hacking.

Recently, web 2.0 is becoming issue can provide a web based services and the technology is developing rapidly. In addition a variety of platforms on the web and SDK(Software Development Kit) is available from various aspects, web services, a trend that is rapidly growing user. But the development of security systems cannot follow the speed and These weaknesses are provided in the Web service by using illegal methods of information acquisition. Therefore, in this paper, we analyzed information for checking a variety of illegal access on Web services. Also, we designed and implemented Web Service-Hacking Pattern Recognition System for which warns the dangerous fact that as recognized hacking through comparisons the hacking patterns which have classified from the hacking method of existing system.

Using the mobile device, such as Smartphones tablet PC, online banking and e-commerce, as well as process and to their work. While going to high availability and convenience of mobile devices castle, SNS, letters, using an email Smishing financial fraud and leakage of personal information such as crime has occurred many. Smishing smartphone accidents increased sharply from 2013, MERS infection cases, landmine provocative events, such as the delivery of Thanksgiving has occurred cleverly using social engineering techniques. In this paper, i analyze the trends in Smishing hacking attacks on mobile devices since 2014. With regard to social issues, it analyzes the process of hacking attacks Smishing leading to financial fraud to mobile users. And, in this paper, i propose a secure way and measures of financial damage for mobile Smishing hacking.

The characteristics of International Hacking is that because even if with tracing techniques, nobody can find Real IP address of the attacker so it is true that Great difficulty in the investigation. so that an attacker goes through the Proxy Server Many times and they use techniques of IP Spoofing to hide their IP address. In this paper, study How attackers use IP Spoofing Technique and the application of Proxy Server. In addition, to Propose IP Spoofing attacks through the Proxy Server attack and defend methods also IP traceback methods so this study materials will contribute to the development of International Hacking and Security Protection Technology.

Ethical hackers are using different tools and techniques to encounter malicious cyber-attacks generated by bad hackers. During the software development process, development teams typically bypass or ignore the security parameters of the software. Whereas, with the advent of online web-based software, security is an essential part of the software development process for implementing secure software. Security features cannot be added as additional at the end of the software deployment process, but they need to be paid attention throughout the SDLC. In that view, this paper presents a new, Ethical Hacking - Software Development Life Cycle (EH-SDLC) introducing ethical hacking processes and phases to be followed during the SDLC. Adopting these techniques in SDLC ensures that consumers find the end-product safe, secure and stable. Having a team of penetration testers as part of the SDLC process will help you avoid incurring unnecessary costs that come up after the data breach. This research work aims to discuss different operating systems and tools in order to facilitate the secure execution of the penetration tests during SDLC. Thus, it helps to improve the confidentiality, integrity, and availability of the software products.

In this paper, we describe the system which can protect the major information from keyboard-hacking. These days the securing information matters for pc-users are becoming more important as the internet business grows rapidly, and the ubiquitous computing environment is open for everyone. Therefore, the keyboard-inputting information is necessary to be protected properly against the malicious attack. In this paper, we propose the keyboard-hacking prevention system using a Java Card, and show the conveniency and efficiency in the results.

동영상에서 학습을 통한 특정인의 탐지는 한 개의 프레임 당 많은 시간이 소모된다. 따라서 특정인의 위치를 파악하면서도 탐색할 프레임의 수를 줄이는 것이 필요하다. 우리는 관찰되는 장소의 특징을 이용하여 일정 범위를 생략하는 탐색 기법을 제안하고 성능을 측정하였다. 실험결과 제안한 방법에서 어느 정도 유의미한 결과를 얻을 수 있었다.
