What is Crypren Ransomware

Crypren Ransomware is a type of malware that compromises your data by running encryption with the .ENCRYPTED extension. For instance, 1.mp4 or other regular files will be changed to 1.mp4.ENCRYPTED or similarly. Usually, due to asymmetric algorithms that are applied during encryption, the inflicted data becomes almost impossible to unlock. However, thanks to a security researcher named pekeinfo, there is no need in paying for decryption software. Besides that, we should point out that after the malware has finished the first step, it drops the READ_THIS_TO_DECRYPT.html file in each folder containing affected files.
