How to remove Kb2j4 ransomware and recover files

Easy tips to delete Kb2j4 ransomware and decrypt data

Kb2j4 ransomware encrypts stored files and then demand ransom payment for the decryption. During the encryption process, it appends .kb2j4 extension to the filenames of each of the infected files. For example, it renames 1.jpg to “1.jpg.Ge1wMvvmzKscu80EPt8JMO9zC-0HiOqqh-zaaMgSL9vkuGtyKhVlaN-P-zQwJ1oQ.kb2j4”, and so on.

As a ransom note, it creates “EtbD_HOW_TO_DECRYPT.txt” text file.  This ransom note informs the victims that their files have been encrypted and all personal data, financial reports and important documents are ready to be disclosed. To decrypt the data and avoid them being ex-filtrated, they are asked to purchase a unique decryption tool from the people behind the infection.

There is a Tor website link mentioned in the note for the communication purpose. At the end, the ransom note warns victims of against certain actions that may result in permanent data loss. Typically, it is not possible to decrypt the files without using a unique decryption tool that the crooks have. Victims can restore the files for free if they have existing backups.

However, even if you belong to those having no such backups, you should strongly be advised against paying/ contacting the crooks. These people are not reliable. They may provide you with no decryption tool and just disappear leaving you without your files, once you submit the ransom fee. Contacting the shady people is not recommended because the link might contain malicious scripts to cause system infection –once being clicked.

The Kb2j4 ransomware might not be capable of doing any damage to this automatically created backup. Using third party data recovery tools is another data recovery option for you.
