BestBuy Virus — How Did I Get It?
BestBuy virus samples can be spread using a multitude of ways depending on their exact type. Various hacking groups can create their own versions and send them using multiple distribution methods. This means that several iterations of the BestBuy virus can be active at the same time. Usually the most common technique is the coordination of phishing campaigns that are primarily sent via email messages. The hackers will impersonate well-known companies and services and prepare the necessary content that will infect the recipients with the BestBuy virus. The other technique which is often used is the creation of numerous sites. They will pose as the official or affiliate pages of these companies and in order to fool the users into believing that they have accessed the real site they can use stolen or fake content. The pages are hosted on addresses that are almost identical and the sites can include security certificates that are self-signed or stolen.
The pages can be advertised using other methods as well, a popular one is the distribution of browser hijackers which are dangerous plugins made compatible with the most popular web browsers. They are usually uploaded to the relevant repositories using fake or stolen developer credentials. The elaborate descriptions posted may include videos and user reviews along with promises of adding new new features that may be related to the BestBuy site features. These extensions may also promise discount codes or other alluring extras.
In many cases executable files can be generated which will lead to BestBuy virus infections, most of them can be categorized into two main groups:
- Malicious Documents — The hackers can craft macro-infected documents that can range from spreadsheets, presentations, databases and text files. As soon as they are opened by the victims a prompt will be spawned asking the victims to enable the built-in content in order to correctly view the document. If this is done then the virus infection will follow.
- Application Installers — The virus installation code can be placed inside application installers that are often by end uses. They can be spread over the phishing methods and emails, as well as uploaded to file-sharing networks like BitTorrent.
At any time the distribution techniques can shift and other methods can be employed. This includes delivery by other malware which have already impacted the target hosts.
BestBuy Virus — What Does It Do?
As there are numerous variants of the BestBuy virus and no single analysis can be made as a representative threat of the whole family in this article we will present the majority of malicious actions that are often executed.
The infections can begin with a data harvesting module which is able to hijack sensitive information that can expose the identity of the victims. It can also generate a profile of the installed hardware components. This data can be fed to another module which can generate an unique ID that is associated with each computer.
Based on this data the engine can then proceed with the actual intrusion by setting it as a persistent threat which means that it will start as soon as the computer is powered on. Advanced virus samples can also block access to the recovery boot options thus making it impossible to follow most manual user removal guides.
Following the successful infection the BestBuy virus can then proceed with other system changes. They can range from Windows Registry modifications to changes in configuration files. This can lead to severe performance issues, the inability to run certain functions and data loss.
Bear in mind that if the infection has come through a browser hijacker then the code can retrieve all stored information and redirect the users into always opening the designated hacker-controlled fake Bestbuy virus site.
What’s more dangerous is the fact that the active infections can be used to deploy other malware threats to the victim systems. POpular ones include the following:
- Ransomware — These file encrypting viruses will process user data based on a built-in list of target file type extensions. A strong cipher wll be used to encrypt all of them and the victim users will be extorted to pay a ransom fee.
- Trojans — These viruses will allow the criminals to establish a secure and persistent connection to a hacker-controlled server. It will allow the hackers to spy on the victims in real-time, take over control of their computers and steal any file at any time.
- Miners — Cryptocurrency miners are among the most dangerous viruses which can even be under the form of simple scripts. They will download numerous small-sized mathematical tasks which will place a heavy toll on the performance of the system. They will take advantage of resources like the CPU, memory and hard disk space. As soon as one of them is reported as complete the hackers will receive income as compensation which will be wired directly to their digital wallets.
- Adware — The BestBuy virus can also implant various adware on the infected computers. This means that while browsing ordinary sites the victim users may stumble upon ads and banners that they have not seen before. This is either a real-time manipulation of the web browsers or other dangerous behavior which is observed by the users.
One of the most dangerous effects of having such a virus installed on a given computer is the fact that the made infections can be used to gather any sensitive files that the hackers can deem as useful. Existing malicious modules can be used to delete information such as backups, restore points and shadow volume copies.
If the infection is related to the creation of a fake site that imitates the real BestBuy shopping portal the users can be presented with phishing offers and login prompts. This means that the users may be enticed to enter in their login credentials to the BestBuy site.
As this virus appears to be targeting the e-commerce site it may be linked with banking Trojans. These are small-sized malware which will monitor if the victims access online banking services and financial applications. The keystrokes, mouse movement and any user input will be captured with the intention of gaining access to their accounts. Bank transfer information can be edited without the users noticing which will automatically make the transfer to the account of the criminals.
In certain cases the gained information can be cross-linked with other databases and repositories of stolen credentials. This is particularly useful if the attacks are comanded from a criminal group, the harvested information can then be sorted by them and sold to interested parties or abused further. In many cases based on the collected information the hackers can launch various social engineering or blackmail campaigns against the victims.
