Fabio Assolini
termsecurity
The Brazilian malware analyst on Kaspersky's Global Research and Analysis Team whose published work is the main public record of how Brazilian banking fraud actually operates - boleto manipulation, overlay attacks and the families that became known as the Tetrade.
His significance is documentary. Brazilian banking malware was for years a phenomenon everyone in the region experienced and almost nobody outside it could read about, because the analysis existed only in Portuguese or not at all. Publishing that research in English, with samples and technique names, is what turned a local nuisance into an internationally understood threat class - and it is why the rest of the world eventually recognised Brazilian crews as innovators rather than imitators.
