Revisão sistemática sobre a metodologia de ataque dos Worms Iloveyou, Wannacry, Mirai e Lion nos sistemas operacionais Windows e Linux. 2023. Trabalho de Conclusão de Curso (Bacharelado em Ciência da Computação) – Centro Universitário do Estado do Pará, Belém, 2023.https://repositorio.cesupa.br/handle/prefix/466Every day, several devices are attacked by different threats around the world, affecting both home users and governments or large institutions, making information security specialists have to work harder to defend against these attacks. Typically, attackers use malwares as an attack instrument, one of the most used in recent times being worms. To be successful in attacks, the attackers and cybercriminals develop worms focused on the most used operating systems: Windows and Linux, both of which have different architectures and paradigms. Therefore, there is a great effort by information security specialists to work to protect these two systems. Based on this context, the present work aims to compare the worms: WannaCry, ILOVEYOU, Mirai and Lion, focusing on their attack methodologies and the defense methodologies of their respective target systems, based on a systematic review of articles and academic literatures obtained by searching through repositories and online collections. In the end, we hope that this article contributes to the future research in the area of cybersecurity.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/IoT (Internet of Things)Sistema operacionalProtocolo de Controle de Transmissão (TCP)Segurança de dadosMalwareFerramentas de segurança da informaçãoCIENCIAS EXATAS E DA TERRATrabalho de Conclusão de Curso
