What is WannaRen Ransomware?
WannaRen Ransomware might sneak onto your system by exploiting a vulnerability known as EternalBlue. If it does, all your documents, pictures, and other valuable files could become encrypted. As a result, your computer would be unable to recognize and open the affected files. The malware’s creators claim that users who pay ransom can get their files decrypted, but we recommend not to trust them blindly as they could be lying. What we do advise is to remove WannaRen Ransomware from your system if you do not want it to cause you more trouble. If you need any help with its removal you could use the deletion steps provided below this article or a legitimate antimalware tool that could take care of this malicious application. In case you are not sure what you should do yet, we invite you to read our full article and learn more about the malware.
Where does WannaRen Ransomware come from?
As said earlier, WannaRen Ransomware might get in while exploiting a vulnerability called EternalBlue, but before it could do so the targeted victims might be tricked into opening an infected setup file. The sample tested by our researchers at Anti-spyware-101.com appeared to be a malicious Notepad ++ setup file. It is most likely that users could come across such installers on torrent and other unreliable file-sharing web pages.
Thus, if you want to prevent ransomware or malware alike from entering your system, you should take care of your computer’s vulnerabilities and never download installers or any other files from questionable websites. Also, it is advisable to keep away from suspicious email attachments too as it is another poplar way to distribute malicious applications. If for some reason you feel like you cannot avoid opening a file from an unreliable source, we recommend scanning it with a legitimate antimalware tool first so that you would learn if it is malicious or not before you launch it.
How does WannaRen Ransomware work?
The first thing that WannaRen Ransomware ought to do after it starts running in the background is check if the infected system is a virtual machine. If it is not, the malicious application should start encrypting various types of documents, pictures, archives, and so on. In other words, it might encrypt all files that could be personal and might be impossible to replace. Therefore, data that can be replaced like files belonging to the operating system or other software installed on the computer should remain unencrypted.
After all targeted files are enciphered, WannaRen Ransomware should display a window on the victim’s screen that should contain a ransom note. Our researchers say that the note could be written in Chinese and that it may ask to pay 0.05 BTC in exchange for getting all the threat’s encrypted files decrypted. As you probably realize, you cannot know for sure that the hacker’s decryption tools will work, and you will not get scammed. Naturally, if you do not want to take any chances, we advise not to pay ransom.
