The present study tries to investigate the Brazilian hackers´ artistic and communicational manifestations. We tried to understand how they use the digital technology for expression of their identities and transmission of messages in defaced homepages. The integration of different chains of thinking made it possible to build a schematic diagram and the establishment of conceptual categories for a graphic analysis and for the analysis of the messages present in the defacements by the Brazilian hackers. From these analyses we could see that the Brazilian hackers express their identities through their nicknames and defaced pages. These pages have a common underlying structure marked by the linearity, the identification of the one(s) responsible for the defacement, the message left for the administrator of the defaced page, the personal statements and the exhibition of the elements for contact with the defacer(s).
