Short Message Service (SMS) is widely used to provide communication between users around the world. In the last years, it has become a lucrative way for cybercriminals to infect mobile devices with botnets and launch malicious attacks without the user's knowledge such as: SMS spam and SMS premium rate fraud. SMS spam is one of the dangerous malicious activities as the user is charged for each sent SMS spam. Existing solutions to this issue are no longer adequate as they are either costly in terms of resources, inefficient, or require user intervention with some knowledge on security. In this book, we design, analyze, and implement a system that detects any attempt to send out malicious SMS spams from the mobile device. The proposed system combines the rule-based and the content-based approaches into one detection process. It achieves good performance in terms of detection time and execution cost, and offers a good tradeoff between resilience against attacks and user interaction with the system. This book is intended for multiple audiences: academic, professional, students, and anyone else who is interested in IT security, and particularly in mobile security and botnet detection.
Hacker Techniques, Tools, and Incident Handling begins with an examination of the landscape, key terms, and concepts that a security professional needs to know about hackers and computer criminals who break into networks, steal information, and corrupt data. It goes on to review the technical overview of hacking: how attacks target networks and the methodology they follow. The final section studies those methods that are most effective when dealing with hacking attacks, especially in an age of increased reliance on the Web. Written by a subject matter expert with numerous real-world examples, Hacker Techniques, Tools, and Incident Handling provides readers with a clear, comprehensive introduction to the many threats on our Internet environment and security and what can be done to combat them.
The Internet played a pivotal role in some of the most memorable instances of political activism in recent years. 1999's “Battle of Seattle” saw more than 70,000 protestors come together by means of online organizing to take on the World Trade Organization. Similar ad hoc groups were assembled largely with the aid of decentralized online information sites at the April 2000 World Bank protests in Washington, D.C.; at the Republican and Democratic Convention demonstrations; at George W. Bush's inauguration; and most recently at the World Economic Forum protests in New York. Cyberactivism is a timely collection of essays examining the growing importance of online activism. The contributors show how online activists have not only incorporated recent technology as a tool for change, but also how they have changed the meaning of activism, what community means, and how they conceive of collective identity and democratic change. Topics addressed range from the Zapatista movement's use of the web to promote their cause globally to the establishment of alternative media sources like indymedia.org to the direct action of “hacktivists” who disrupt commercial computer networks. Cyberactivism is essential reading for anyone interested in understanding the impact of the Internet on politics today.

Introdução ao Pentest tem o intuito de capacitar o leitor a entender e a realizar o pentest – uma auditoria minuciosa sobre falhas e vulnerabilidades em computadores e redes – e, assim, buscar a melhor forma de solucionar os problemas encontrados. Tendo como base a metodologia Backtrack para o ensino do pentest, que é extremamente didática e adaptada a partir da metodologia OSSTMM de testes de invasão, com certeza este livro fará você se sentir à vontade e confiante ao estudar pentest, tornando o seu aprendizado fácil e rápido. O leitor terá acesso às táticas e técnicas utilizadas na realização do pentest em um ambiente controlado por laboratório e máquinas virtuais. Cada capítulo aborda uma etapa do pentest e, no decorrer da leitura, você: – Conhecerá aspectos básicos de segurança da informação, como a instalação de máquinas virtuais e os primeiros passos com o Kali Linux. – Construirá redes zumbie para ataques DDoS por meio do projeto Perl-bot. – Aprenderá a realizar ataques Man-in-the-Middle remotamente pela internet (pivoteamento via VPN). – Construirá um pendrive infectado com programas maliciosos (o famigerado BadUSB). Fará a escrita e posterior criptografia de um relatório de pentest.[…]
