ESET Research has been tracking a newly discovered banking trojan that has been targeting corporate users in Brazil since 2019 across many verticals affecting sectors such as engineering, healthcare, retail, manufacturing, finance, transportation, and government. This new threat, which ESET dubbed Janeleiro, attempts to deceive its victims with pop-up windows designed to look like the websites of some of the biggest banks in Brazil. These pop-ups contain fake forms, aiming to trick the malware’s victims into entering their banking credentials and personal information that the malware captures and exfiltrates to its C&C servers.
