Resumo. Discutimos um método de recuperação de mensagens apagadas do aplicativo WhatsApp, cujo armazenamento se dá em base de dados utilizando sistema gerenciador de banco de dados SQLite, disponível na plataforma Android. No desenvolvimento da técnica, foram analisadas as estruturas internas do arquivo da base de dados SQLite com potencial interesse para uma investigação forense dessa natureza. Especificamente, foram exploradas as regiões não alocadas (freespace) e desalocadas (freeblocks) das bases de dados SQLite, com foco na recuperação estruturada de mensagens do aplicativo WhatsApp.
