IBM Security scientists have found a new kind of malware focusing on on the internet banking end users in Brazil.
Dubbed Vizom, the malware disguises by itself as preferred video conferencing software package and uses convincing remote overlays to consider in excess of user units in serious-time.
Investigation displays that hackers are providing the malware through spam-based phishing email strategies. According to IBM Security researchers Chen Nahman, Ofir Ozer and Limor Kessem, the new malware also takes advantage of remote overlay tactics and DLL hijacking to evade detection.

After embedded on a compromised Personal computer, Vizom sorts an an infection chain by way of dynamic link library (DLL) hijacking – it pressure-hundreds destructive DLLs by naming its Delphi-primarily based variants with unsuspecting file names observed in directories of genuine videoconferencing software. In Brazil’s case, the DLL is Cmmlib.dll, a file connected with Zoom.
What comes about next is stealthy and treacherous. Through an ongoing online transaction, the malware connects remotely to the compromised Computer system. It produces powerful and plausible HTML overlays and hundreds them in the Vivaldi internet browser in application mode. It then launches a keylogger that logs the user’s every single keystroke when accessing their bank account. The malware then ships the acquired details to the attacker’s command-and-regulate (C2) server.
Vizom can also abuse Windows API functions, simulate mouse clicks and get screenshots.
There are no reviews of hijacking in the US, but attacks have been observed throughout South America and Europe.
