Abstract A grande quantidade de informação que circ A grande quantidade de informação que circula nas redes sociais pode ser útil e até necessária para descobrir novas ameaças de segurança. A análise manual destes dados não é prática devido ao seu elevado volume, portanto novos métodos de filtrar e classificar este fluxo de informação devem ser estudados. Pretendemos com este trabalho produzir uma aplicação capaz de detetar ameaças à segurança informática a partir da rede social Twitter de forma automática, precisa e eficiente. Para isso recorremos a técnicas de aprendizagem automática implementadas em sistemas distribuídos para alcançar um bom desempenho para a grande quantidade de dados que precisa de ser processada. Esta aplicação será capaz de extrair informação do Twitter e classificá-la de forma correta para ser analisada, dispensando intervenção manual extensiva por parte do analista. Esperamos então explorar novas soluções na área da segurança informática, necessárias numa realidade onde as organizações dependem da segurança dos seus sistemas informáticos para continuar a desempenhar as suas funções. a continuar a desempenhar as suas funções.
