Bizarro is yet another banking Trojan family originating from Brazil that is now found in other regions of the world. We have seen users being targeted in Spain, Portugal, France and Italy. Attempts have now been made to steal credentials from customers of 70 banks from different European and South American countries. Following in the footsteps of Tetrade, Bizarro is using affiliates or recruiting money mules to operationalize their attacks, cashing out or simply to helping with transfers.
In this article we analyse the technical features of the Trojan’s components, giving a detailed overview of obfuscation techniques, the infection process and subsequent functions, as well as the social engineering tactics used by the cybercriminals to convince their victims to give away their personal online banking details.
