In January 2017, IBM X-Force research reported the development of a new remote-access malware code targeting Brazilian banks. The malware, dubbed Client Maximus, was observed in ongoing campaigns and continues to target online banking users in the country. The development of Client Maximus, which is believed to be commercially available in Brazilian fraud and cybercrime communities, continues as new variants of the malware emerge.

IBM X-Force recently analyzed a new and upgraded version of the malware. Client Maximus appears to have been written specifically for attacks against Brazilian banks. Analysis of different components of this code led our researchers to the overall understanding of the growing sophistication of cybercrime tools in Brazil.
