Vizom Trojan – Virus Infection Methods
The Vizom Trojan is a newly listed malware aimed against Brazilian online banking users. It has received the name Vizon from the security engineers who made the code analysis. According to the known information, it follows the familiar tactics as observed by other similar banking Trojans — this is a group of computer viruses that are designed to hijack personal user’s information and login information to financial services: payment portals and online banks.
These kinds of infections are mainly sent through several common infection strategies. Rarely the viruses are sent as direct executable files, most of the time they are carried in payload data — other files that when run will automatically deploy the virus in the background. Two of the most popular types are the macro-infected documents and the application installers. The documents themselves are made in the most popular office formats that are used by Internet users: presentations, databases, spreadsheets, and text documents. When they are opened by the users a prompt will ask them to enable the built-in scripts to correctly view the documents. This triggers the Trojan deployment. On the other hand, the application installers are much more varied as the hackers can, in practice, take any legitimate setup file and insert the virus code in it.
All of the virus data can be delivered using common manipulative tactics that are known to us from other similar malicious campaigns. They focus on the distribution of the files through different means by faking trusted parties: friends, relatives, companies and services. They can be hosted in similar sounding web sites that include hijacked content or even self-signed security certificates.
In a similar fashion, the hackers can send out email messages that are designed in a similar fashion. They are based on typical templates and will either attach or link the relevant files. All virus-related data can also be carried on file-sharing networks (BitTorrent) and on online communities like social networks, chat rooms, and forums.
Vizom Trojan – Virus Capabilities
The Vizom Trojan uses a DLL Hijacking approach during the initial infection. The virus agent will deploy itself in the legitimate Microsoft Windows directory structure in DLL files. They belong to the system and by hooking onto them the virus will mask its presence. The collected samples so far show that the malware will hide as a popular videoconference program. This tricks Microsoft Windows into loading the code into memory.
The Vizom Trojan uses the distinct tactic of using the legitimate Vivaldi web browser to disguise its presence. It contains components that are part of it and this will further confuse the system. This is a different type of a security bypass, an important feature of most advanced malware threats.
The actual Trojan functions will follow, several components are launched when the malware agent is activated. This virus comes in an encrypted form, it will be decrypted by a special component designed to do so. At the beginning of the infection, a data gathering procedure will be started. It will be tasked to obtain statistical information that will be relayed to the hacker operators. Other configuration options can task is to create a report of the installed hardware components, operating system values, and other kinds of data. It can be abused to carry out crimes such as identity theft and financial abuse. The persistent infection is done by modifying browser shortcuts and running them in the background, this will keep the virus infection alive. This works with the most popular ones: Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Bank-specific secure browser, and Microsoft Edge.
The main goal of the malware will be to create a secure connection to a hacker-controlled server — it allows the criminals to take over control of the systems and hijack any users data. A dangerous part of the malware is the overlay functionality that automatically detects if any of the supported online banks and financial services are loaded in a web browser. It will hijack all entered in information and make it available to the hackers: this works both for the keyboard input and mouse movement. This is also connected to the built-in keylogger function: it can also function with other services and can be launched independently.
At this time the attack campaign is focused on Brazilian targets, however, smaller campaigns have been reported in other countries in South America and Europe as well. As there is no information regarding the hacking group, we presume that they are very experienced to have created the malware from scratch.
