Brazil is one of the regions that are most affected by banking Trojans developed by local cybercriminals. While most of the Brazilian banking Trojans concentrate on infiltrating victims in the region, there are many cases in which the infection rate rapidly increases, and users from other parts of the world also become affected by the attacks. Recently, malware researchers identified a set of four banking Trojans that started their activity in Brazil, but soon spread on a global level. The four threats are being referred to as the 'Tetrade' and their individual names are Melcoz, Grandoreiro, Javali, and Guildma.
It is not a surprise that Brazilian cybercriminals are trying to expand their operations by going after victims in other parts of the world. While such attempts have been made in the past, they have had very limited success due to the low complexity of Brazilian-made malware. However, modern banking Trojans like the four mentioned in the first paragraph are much more advanced, and they have the ability to execute complex and stealthy attacks that are very difficult to mitigate without using suitable anti-malware software.
Tetrade Family of Banking Trojans May be Able to Deal with Bank Security Measures
It is important to add that one of the reasons why the Tetrade is considered to be so dangerous is because these malware families are capable of bypassing a wide range of security measures that Brazilian financial institutions have implemented successfully to combat banking malware. Modern Brazilian Banking Trojans are able to bypass two-factor authentication measures, falsify e-tokens, and steal a lot of information from compromised devices.
The banking Trojans part of the Tetrade family target Windows devices exclusively, so you should take the required steps to protect your system. The best way to do this is to rely on a trustworthy antivirus software suite. You can also stay safer by not interacting with suspicious files coming from unknown sources.
