How is this made possible? The hacker takes care to copy the real export list of the legitimate DLL (in this case, Cmmlib.dll) – with certain changes. The DLL, for example, is named Cmmlib.dll, which is a file associated with Zoom. IBM officials pointed out that operating systems can get tricked into loading the Vizom malware.

In this case, Vizom names its Delphi-based variants with labels that appear to be legitimate since they are recognized in a software’s directories.

Vizom creates variants that are expected by legitimate software in their directories But even after all these precautions, cyberattackers are still succeeding in finding loopholes and developing new malware to exploit those loopholes. In fact, the whole idea of adopting DevOps methodologies like Continuous Integration and Delivery was to decrease the growing complexity involved in developing software systems. What is both ironic and concerning here is that video conferencing software is constantly being updated to amp up security. Until now, it was only Brazilian bank accounts that had been getting compromised, but as noted previously there are reports of it happening in other countries as well.

This is made possible through disk manipulation because of the hijacking.ĭLLs run Microsoft‘s Windows operating systems, putting millions of PC users across the globe at a higher risk of getting duped.

DLL hijacking, on the other hand, is a type of cyberattack that tries to manipulate the Windows search and load algorithm, giving a malicious hacker unauthorized access to inject code into a specific application.

After getting access to an unprotected Windows PC, Vizom will first strike the AppData directory, harnessing DLL hijacking that allows the malware to forcefully download harmful DLLs.įor those of you who aren’t aware, DLL or dynamic link library is a file that contains code for commonly used program functions on a PC. Once downloaded, the malware begins work on a vulnerable operating system to begin the infection change. Spam-based phishing campaigns are the starting point for the spread of the Vizom malware that disguises itself as a popular video conferencing software. What is Vizom malware?Ĭhen Nahman, Limor Kessem, and Ofir Ozer shocked the world when they announced that the trio had discovered a new malware that attacked people who use video conferencing software. In this article, we’ll go into specifics of how Vizom works, what makes it so dangerous, and how the malware authors use DLL hijacking and overlays to their advantage. Even though Vizom is currently mainly being used to target Brazilian-based accounts, there have been a handful of reports of it being used against bank accounts in other South American and European countries as well, so it’s likely to spread further. There has been a drastic increase in malware attacks for 2020 as cybercriminals have been eager to take advantage of the chaos of this year. What’s particularly concerning about Vizom is its use of malicious DLL’s (Dynamic Link Libraries) to trick the victim’s operating system before loading legitimate DLL’s in place. Referred to as ‘Vizom’ by the team, the code utilizes remote overlay attacks to siphon sensitive financial data and make fraudulent transactions from victims bank accounts.

Security researchers working with IBM Security recently uncovered a new malware code that is being used to attack online banking users in Brazil. This blog was written by an independent guest blogger.
