According to a report released by Kaspersky researchers this week, four Brazilian banking-trojan families have started to appear globally. The families are Guildma, Javali, Melcoz, and Grandoreiro, together known as Tetrade. “In the past, Brazilian criminals primarily targeted customers of local financial institutions. That changed at the beginning of 2011 when a few groups began experimenting with exporting basic trojans abroad. This year, four families known as Tetrade have implemented the necessary innovations to take their distribution worldwide.”
The head of Kaspersky’s GReAT in Latin America stated, “What’s more, they are continuously innovating, adding new tricks and techniques to hide their malicious activity and make their attacks more lucrative. We expect these four families to begin attacking more banks in additional countries, and new families to pop up. That’s why it’s so important for financial institutions to monitor these threats closely and take steps to boost their anti-fraud capabilities.”
