In Omicrono we have talked a lot about ransomware, a type of malware that encrypts our files and asks us for a ransom to recover them.
Normally the bailout involves paying in Bitcoin to prevent the transfer being tracked; But there are also more strange cases, in which the creators of the code look for some type of achievement or that the users do something concrete.
The most curious case so far was perhaps ransomware that forced us to learn to protect ourselves from ransomware. However, the latest malware that is haunting the Internet far surpasses it.
RensenWare, malware with video game included
It’s called RensenWare, and it’s become quite a network sensation for the wrong reasons. When we are infected, it works exactly like other ransomware, encrypting all files with certain extensions .
A window then informs the user that it has been infected, and that it still has an opportunity to recover its files ; But this is where RensenWare differs from other ransomware.
The creator does not ask for our money; Instead, it asks us to play a video game and get a high score . If you are thinking that this is not a problem, it is because you do not know the game in question: TH12 ~ Undefined Fantastic Object.
This title belongs to the Touhou saga, a series of shooters very popular mainly between the fans to the sleeve and the anime; The amount of art, comics, video games and videos based on the characters of Touhou is overwhelming, but the most interesting thing is that most have been created by the fans, for the fans.
A hell of bullets to recover your files
Another thing you should know about Touhou games is that they are difficult . Very difficult. They belong to a sub-genre known as “bullet hell”, in which the screen is filled with projectiles that we have to dodge while we continue shooting.
Only expert players are able to remain calm, especially at the highest levels of difficulty. And that’s what RensenWare wants you to play.
RensenWare will only decrypt your files if you get 200 million points on the “LUNATIC” difficulty level (the highest of all). That is simply impossible for most players, let alone if we only play “casual” titles.
If you think this is too cruel, you’re right. It turns out that in reality from the beginning all this was a joke of its creator, that went out of hand . He claims that his intention was not to create malware, although in the end that was what he did.
The creator of RensenWare has already publicly apologized; And has published a tool that hacks the game to get the amount of points needed to decrypt the files.
Unfortunately, the damage is already done and the code has already been copied and is being distributed over the network. So you know, be careful what you install; Or you may have to face the departure of your life.
