By September 2012, an Assassin cell was located in São Paulo. Around that time, the team had to move safe houses for at least the second time and they suspected that there was a double agent in the team who was leaking their position to the Templars, which forced them to delay their progress and find the spy. After having done so successfully, they cut off contact with the Assassin headquarters and presumably moved to another city.
As of 2014, they still had not been heard from.
By 2015, the Assassins had managed to gain dominance in Brazil.
