The Brazilian cybercriminals behind four banking Trojans collectively dubbed "Tetrade" have decided to expand their business and started targeting victims internationally, Kaspersky's security researchers reveal.
The four banking Trojan families - Guildma, Javali, Melcoz and Grandoreiro - have been active for years, but started emerging in attacks in North America, Europe, and Latin America only last year.
The first malware family on the list, Guildma, has been active since at least 2015, exclusively targeting banks in Brazil.
The malware has made victims in Mexico too, and is the most widespread globally of the four Tetrade Trojans.
"Guildma, Javali, Melcoz and Grandoreiro are examples of yet another Brazilian banking group/operation that has decided to expand its attacks abroad, targeting banks in other countries. They benefit from the fact that many banks operating in Brazil also have operations elsewhere in Latin America and Europe, making it easy to extend their attacks against customers of these financial institutions," Kaspersky concludes.
