International cybercriminals slicker than ever

A new study from Kaspersky Labs confirms what Dr. No always knew – the criminal mind has to be sharper than that of the honest person. Cybercriminals, it appears, have overcome time differences and language barriers and are collaborating in ways that would make the most ardent social media wonk jealous.

The Brazilian and Russian networks are either the most efficient or the readiest to answer questionnaires and are masters at developing localised attack techniques, such as the “Boleto” attacks in Brazil and mobile banking targeting in Russia.

Evidence of co-operation has emerged from common use of user names and above all similar infrastructures being used for criminal activity. The wrongdoers also seem intent on lending each other technology.

“Just a few years ago, Brazilian banking malware was very basic and easy to detect. With time, however, the malware authors have adopted multiple techniques to avoid detection, including code obfuscation, root and bootkit functions and so on, making their malware much more sophisticated and harder to combat. This is thanks to malicious technologies developed by Russian-speaking criminals. And this cooperation works both ways,” said Thiago Marques, security researcher at Kaspersky Lab.
