Another in our occasional series demystifying Latin American banking trojans
Ousaban is a Latin American banking trojan active exclusively in Brazil. ESET has been tracking this malware family since 2018. In common with most other LATAM banking trojans, Ousaban uses overlay windows to steal credentials and more from financial institutions. However, unlike most other LATAM banking trojans, Ousaban’s developers have extended the use of overlay windows to steal credentials from popular regional email services. In this installment of our series, we examine its main features and many connections to other Latin American banking trojan families.
Characteristics
Ousaban is written in Delphi, as are the vast majority of the other Latin American banking trojans ESET is tracking. And, as do many of them, Ousaban shows signs of active and continuous development.
