What is JoJoCrypter Ransomware

Developed on Node.js, JoJoCrypter is a malicious program that functions as a data-encryptor. A thorough investigation conducted recently shows there is a .jojocrypt extension assigned to each of the files. To illustrate, a non-encrypted 1.mp4 will turn into 1.mp4.jojocrypt as a result of infection. Along with this, it is also known that JojoCrypter uses RSA-2048 and AES-192 algorithms to cipher innocent files. It also creates a short ransom note how to recover your files.txt with following content.

Unfortunately, the decryption with third-party tools appears to be an impossible task. The encryption chains are too strong and flawless to crack. This is why the only option (apart from paying the ransom) is to recover your files using backup or data-recovery tools. Otherwise, you will be forced to pay for the keys proposed by cybercriminals, which is mentioned in the ransom note dropped on your PC after encryption. Swindlers are not using too many words for describing what happened, instead, they attach their e-mail address to be contacted for further instructions. After reaching out to them, they will ask you to buy decryption software in BTC or any other cryptocurrency they use. Although this is a viable solution to restore your data, we advise against having any deal with cybercriminals. Most examples show that people get fooled and end up receiving no decryption software. Whatever the case, it is important to delete JoJoCrypted from your computer. Below, you will find both removal and data-recovery instructions.
