BansomqareWanna Virus – Infection Spread

The BansomqareWanna virus can be delivered using numerous methods depending on the target users. There are several main methods that are being used to deploy ransomware such as this one.

The main method is to utilize email messages that contain the malware code. The hackers use social engineering tricks in order to coerce the victims into installing the malware threats. Usually this is done by inserting hyperlinks in the body contents of the sent messages. They are usually designed in a way that resembles legitimate senders, this is done by taking legitimate text and graphics from official sites. Another method is to attach the files directly. In the last few years this is combined with two approaches that have gained popularity:

  • Software Installers — The criminals behind the BansomqareWanna virus may the setup files of legitimate and well-known computer software and bundle the malware code into them. Usually the hackers choose well-known titles such as system utilities, creativity apps, games and etc.
  • Malware Documents — The hackers can bundle the virus code into files of different types (rich text documents, spreadsheets & presentations). Once they are opened by the victims a notification prompt appears that prompts them to enable the built-in scripts (macros). If this is done the virus will be downloaded from a hacker-controlled site and executed on the local computer.

The developers of the BansomqareWanna virus can also use various browser hijackers to distribute the dangerous code. They represent malware plugins made for the most popular web browsers: Google Chrome, Internet Explore, Safari, Opera, Mozilla Firefox and Microsoft Edge. They are usually programmed to redirect the victims to a hacker-controlled site by changing default settings like the home page, new tabs page and search engine. During this initial deployment is complete the BansomqareWanna virus is delivered.

Another strategy would be to use various web scripts such as banners and pop-ups which can also be placed on legitimate sites through ad networks. The ransomware can also be deployed onto file sharing networks such as BitTorrent as well.

BansomqareWanna Virus – Technical Data

The initial security analysis shows that the BansomqareWanna virus does not originate from any of the well-known malware families. It is possible that the code has been written entirely from scratch by the hacker or criminal collective. The other possibility is that it is a cusomized strain bought from the underground black market.

The analysis reveals that it follows a basic infection pattern. Once the threat has been deployed it starts an information gathering that starts to harvest sensitive information from the compromised machine. The collected data can be categorized into two categories:

  • Anonymous Data — It is composed of metrics that are related to the operating system configuration. The engine also creates a detailed profile of the hardware components and regional settings.
  • Personal Data — The collected information can be used to directly reveal the victims identity — their name, address, phone number, geolocation, passwords and various account credentials.

This information can be used with a stealth protection module in order to bypass any found applications that can interfere with the malware execution. This includes all kinds of anti-virus products, sandbox and debugging environments & virtual machines hosts. The engine can be programmed into bypassing their real-time modules or altogether remove them. In certain cases the virus can remove itself to avoid detection. e

The BansomqareWanna virus then proceeds with system changes. They can affect the Windows Registry or the boot options. Depending on the specific configuration the malware can remove the ability to boot into the recovery menu. System modifications can also result in poor overall performance, as well as the inability to start certain operating system services or applications.

Such malware can also be used for additional malware delivery. Further updates tot the threat can create a network connection to a hacker-controlled server. It can be used to retrieve the gathered information and also function similar to a Trojan horse by allowing the operators to spy on the victims in real time and take control of the computers at any given time.

BansomqareWanna Virus – Encryption Process

The ransomware component is launched once all prior modules have executed correctly. Like other similar threats it uses a built-in list of target file type extensions. An example file list may target the following:

  • Archives
  • Documents
  • Backups
  • Images
  • Music
  • Videos
  • Databases

As a consequence all victim data receives the .bitcoin extension. A lockscreen instance that is reminiscent of WannaCry is then launched which counters any ordinary computer interaction attempts. It displays the ransom note which reads the following:

What Happened to My Computer?
Your important files are encryped.
Many of your documents,photo,video,databases and other files are no longer accessible because he have been encryped.Maybe you are busy looking for a way to recover your files,but do not wasteyour time. Nobody can recover your files without our decryption service.
Can I Recover My File?

You can decrypt some of your files for free .
The bitcoin address will be saved to the “bitcoin2018.txt” file

If your computer got compromised and is infected with the BansomqareWanna ransomware virus, you should have some experience with removing viruses before tampering with it. You should get rid of the ransomware fast before it can spread further on the network and encrypt more files. The recommended action for you is to remove the ransomware completely by following the step-by-step instructions written below.
