The banking Trojan, which mainly targeted Brazil, Mexico and Spain, locked the victim’s screen, recorded keystrokes, simulated mouse and keyboard activity, and displayed fake pop-up windows

This week, Brazilian law enforcement took action to counter the Grandoreiro banking malware in a joint effort also supported by the ESET research team, which contributed technical analysis, statistics, and domain names and IP addresses of known C&C servers.
The operation – which was further supported by Interpol, the Spanish police and Caixa bank – was targeted at individuals believed to be at the top of the Grandoreiro pecking order. Grandoreiro has targeted victims in Brazil, Mexico, Spain and, most recently, Argentina, causing millions in fraud losses since at least 2017.
