Four sophisticated malware families are ramping up their techniques and actively spreading to new countries, including the U.S., Europe and Latin America. Kaspersky researchers say four Brazilian banking-trojan families (Guildma, Javali, Melcoz and Grandoreiro) have taken their distribution global, according to a report published on Tuesday. The four families known as Tetrade have implemented the necessary innovations to take their distribution worldwide. The malware is distributed via compromised websites as well as its third-party communications on C2.
