The downloaded VBS file subsequently proceeds to hold out a collection of anti-sandbox and anti-VM checks, after which it initiates communications with a command-and-control (C2) server to retrieve and execute the us payload.
A 3rd Latin America-based financially motivated actor spotlighted by Google is FLUXROOT, which is linked to the distribution of the Grandoreiro banking trojan.
