Rensenware Ransomware Removal Steps & File Recovery Techniques

Depth-Analysis on Rensenware Ransomware

 

Rensenware Ransomware is a noxious file-encrypting virus which was uploaded to the platform reported as Github.com. The developers of this malware uses the alias “0x00000FF” and then claims to have generated this threat as a joke for the system gamers on “Touhou 12 – Undefined Fantastic Object” produced by Team Shanghai Alice. Although, it is not a typical ransomware virus, because it does not ask the victimized users to pay ransom money in the form of Bitcoins or any type of other digital crypto-currency. Instead demanding the ransom fee, the cyber criminals encode the user's data with AES-128 ciphers and then invites the victims of Rensenware Ransomware to play “Touhou 12” game and generate 12 billion points. However, it is not an easy task and most of the victimized PC users may fail to fulfill the demands of this malware.

Rensenware Ransomware is not a Joke

Cyber security experts reported that the malware uses “rensenware.exe” file to run on the affected machine. Also, it uses 256-bit long unique key to encipher the data stored onto the system. Rensenware Ransomware may encode audio, images, presentations, videos, media projects, spreadsheets and other type of crucial files after successfully invading your PC. According to the malware researchers, the threat adds “.rensenware” file extension to the files enciphered by this ransomware. Hence, the affected system files can be easily recognized. Once it encrypts the computer files, it displays a program window named as “Rensenware WARNING!” onto your system's screen. Moreover, in this program window, there is no close and minimize button are presented.

Rensenware Ransomware Provides a Decryption Tool

Most importantly, the computer users who get infected with this malware are suggested not to close the program window and then download a free decryptor known as “rensenWare_forcer.csproj” from the “github.com/0x00000FF/rensenware_force” which is provided by its developers. This decryptor can be exported as “decryptor.exe” by loading it onto the MS Visual Studio 2008 and its later versions. The decryptor displays an apology note for encoding your files and developing Rensenware Ransomware. However, it is very important to leave the program window opened because if the apps is closed, the decryption tool would not be able to decode the files as it is saved on the memory. Besides, this ransomware is also detected as:

• W32/Trojan.ORYW-8764
• Win32/Trojan.Ransom.786
• Gen:Heur.Ransom.HiddenTears.1
• MSIL/Filecoder_RensenWare.A!tr
