Vigorf Trojan — Overview
The Vigorf Trojan is a family of several popular malware variants which have been used by computer hackers for several years now. The attacks associated with it are being organized in distinct campaigns that have different goals, configuration options and means of distribution.
There are multiple ways that can be used to infect target victims. A popular method is the creation and distribution of malware files — when they are executed the relevant infection will start. A popular strategy is to embed the necessary code into commonly downloaded files — they can be macro-infected documents, app setup files or even “cracks” and software/game patches. Depending on the target victims the hackers can use various file names and descriptions. The most likely way to get infected with the Trojan is to fall for a phishing scam — they are often organized via email messages and hacker-controlled sites. The goal of the hackers is to manipulate the visitors and readers into thinking that they have received a legitimate message or are visiting a safe landing page of a well-known company or service. This is done by hosting the relevant sites and emails on domain names that sound very similar to the companies and organizations which are impersonated, also scam design and layout can be implemented.
The malicious Vigorf Trojan files may also be uploaded to file-sharing networks like BitTorrent where popular pirate data is found. The social engineering techniques can also include popular social networks in which the hackers can create fake profiles or hack already existing ones. The dangerous files can be linked in private messages, public posts and group conversations.
One of the latest campaigns is focused on releasing fake uTorrent torrent client files — the hackers are using version number installer files such as utorrent-2-2-1-2.exe and related. This is intentional as many users may directly search for the program on search engines and download sites. By preparing the hacker sites accordingly they can rank up and the victims may confuse them for legitimate download portals.
One of the first actions of the new and improved Vigorf Trojan is to create a separate user with administrator privileges which will be used by the main engine. This means that the malware will have completed control over the infected computers, allowing it to edit configuration files, remove system data and also manipulate every aspect of the operating system.
According to the available research the malware engine of the Trojan has the capability of creating and editing Windows Registry values — this allows the Trojan to create values for itself and also to modify existing ones. Depending on the actual configuration this can result in performance issues, loss of valuable data and faults in system services.
The local Trojan engine will also connect to a several porn sites located in the Netherlands. They may serve as proxies to hacker-controlled machines which will allow the hackers to take over the contaminated computers. This also includes the possibility to spy on the users and hijack their data.
Some of the newest samples also include a detailed information gathering module — it is used to gather both personal information, machine data and also installed cryptocurrency wallet credentials.
