Rensenware is a ransomware trojan on Microsoft Windows. It shows a picture of Minamitsu Murasa which is an official artwork from the game and a message which tells the user to play Touhou 12: Unidentified Fantastic Object to get the user's files back. The user will need to find the game separately, as because the ransomware does not come with it.
The developer has said that his computer had also been infected during the development. He did not reach a score of 200 million points due to the difficulty of the game, and he uploaded a patch for file decryption and updated the code in GitHub by removing the ransom part but keeping the rest.
This ransomware will encrypt all the files in the computer when the ransomware is executed. After the files are encrypted, the ransomware will display an uncloseable message with the instructions.
This ransomware will crash if it finds some files that cannot be encrypted.
This ransomware does not ask for a certain amount of bitcoins, but rather that the user play Touhou 12: Undefined Fantastic Object in Lunatic difficulty and reach 200 million points to decrypt the data.
This ransomware does not have an encryption key.
