A New Type of Ransomware - Rensenware

The more weab among us may recognize the above character's name, and for those who don't, she goes by Captain Marusa. In this scenario, she's stolen "your precious files," and the only way to retrieve them, instead of paying money to the developer of the ransomware, is to play Touhou 12 - Undefined Fantastic Object. Ok, easy enough, except you have to play the game on Lunatic mode and score 200 million points, which, if you've not played any of the games before, is incredibly hard (I never got past easy mode personally). As Ars Technica reports,

So we were a bit surprised when word started to trickle out about a new bit of ransomware that doesn't ask for money. Instead, "Rensenware" forces players to get a high score in a difficult PC shoot-em-up to decrypt their files.

[...]

The only way to break the encryption lock, according to the warning, is to "score 0.2 billion in LUNATIC level" on TH12 ~ Undefined Fantastic Object. That's easier said than done, as this gameplay video of the "bullet hell" style Japanese shooter shows.

The original creator, Tvple Eraser, created the program as a joke, he had no genuine malicious intent with the program, however when he made to unfortunate decision to share the program's source code, that's when it became an issue. Tvple has since apologized on Twitter for releasing the program, and has released a second program designed to force the program to believe you've already reached the high score. Still, the issue remains, while Tvple has tried to do right, I don't doubt that modified versions exist and will continue to spread.

 

A new, "cut" version of the program has replaced the source code on Github since it has exploded, just to continue to show off the joke for those who are interested in the program, and Tvple has promised not to release anything malicious again.

 

It's just a prank, bro.

It's all fun and games until someone's porn collection gets encrypted...

Time to go pro.

It makes me think of that creepy doll with the white face and rosy cheeks that says "Do you want to play a game?"

In this scenario.

"You have to score 200 million points in this game. But their's a catch, if you don't meet the requirements your data will not be returned to you."

It's actually .2 billion, or 200 million. The creator is Korean, which explains the odd English.

The author released a program that can force it to decrypt files. So it was just a joke program...

I find this pretty funny honestly. 

 

It's comical this even exists. Bravo to the creator.

 

Just gonna drop her orchestral arrangement here because why not.

 

[Doobeedoo]

Pass the high game score to rescue data? Challenge accepted!

[The Benjamins]

They should make it so you have to beat the last persons high score to unlock your stuff.

[BlueChinchillaEatingDorito]

You mean this thing? Yea there's actually a backdoor to decrypt your files.

You'd legit have to be running a Windows XP based toaster oven for your system to not be able to run any of the games in the main Touhou series.

[WereCat]

What's next?

"Run somewhere"?

 

Encrypts all your data and tells you to download GPS tracking app in the phone. It will return the data if you can run 15 miles without slowing down even once under 8mph.

this is incorrect if you read the

you can see is released the source not by accident then regretted his decision and created a tool to fix it. They even said how they were going to remove the encryption part to make it a prank but decided to leave it I.
