How to remove Jycx Ransomware and decrypt .jycx files


What is Jycx Ransomware

Jycx Ransomware (in other classification STOP Ransomware or Djvu Ransomware) is harmful malware, that blocks access to user’s files by encrypting them and requires a buyout. It was released in the last days of March 2023 and hit tens of thousands computers. The virus uses an unbreakable encryption algorithm (AES-256 with RSA-1024 key) and demands a ransom to be paid in Bitcoins. However, due to some programming mistakes, there are cases when your files can be decrypted. A version of STOP Ransomware, that we are considering today, adds .jycx extensions to encrypted files, and therefore got the name Jycx Ransomware. After the encryption, it presents file _readme.txt to the victim. This text file contains information about the infection, contact details, and false statements about decryption guarantees.
