Grandoreiro is a well-known Brazilian banking trojan — part of the Tetrade umbrella — that enables threat actors to perform fraudulent banking operations by using the victim’s computer to bypass the security measures of banking institutions.
It’s been active since at least 2016 and is now one of the most widespread banking trojans globally. INTERPOL and law enforcement agencies across the globe are fighting against Grandoreiro, and Kaspersky is cooperating with them, sharing TTPs and IoCs. However, despite the disruption of some local operators of this trojan in 2021 and 2024, and the arrest of gang members in Spain, Brazil, and Argentina, they’re still active. Kaspersky researchers are now know for sure that only part of this gang was arrested: the remaining operators behind Grandoreiro continue attacking users all over the world, further developing new malware and establishing new infrastructure.
