A Korean student recently developed an anime malware that will demand the user to play a game to recover or access his files. Because of this, many affected users ranted and came bashing the malware's creator.

The new malware is named after an anime-style game, Touhou Seirensen, an undefined Fantastic Object. It is a brand of a ransomware, where it usually informs the user to pay money in order for the program to be removed, IGN explained.

A ransomware is a malicious brand of malware that will hold a user's files thereby locking the computer's functions, Kotaku added. The malware usually explains how users will be able to remove it.

Many victims affected by this malware have lost several million dollars in an effort to retrieve files from hacker's malware. However, the Korean-based student created a Rensenware, a pun on a game that forces the user to play a game and achieve a score of 200 million points to recover the hacked files.

When asked, the Korean-based student explained that he made the malware as a joke for those fans who liked anime games from Touhou Project Series. He didn't expect that the malware will ultimately spread  among gamers and users alike.

He fell asleep after releasing the file to GitHub and when he woke up, he learned through Twitter that his malware had already spread. He realized that the joke he once created became a huge accident thereby affecting not only many users but also him. As an apology, he then created a neutralizing software that was later on released to GitHub where he first exposed the Rensenware.
