Kodc is a type of ransomware discovered by Demonslay335. This type is the updated version of Redl, Piny, and Nbes. Kodc was developed to rename files and issues a ransom note to the victimized users. Usually, it renames the files by appending the .kodc. Another thing is it creates and issues a text file named README.txt, which contains procedures or instructions on how the user will pay the ransom. To explain it simply, the victim should follow the procedure or instructions from the operators of the Kodc ransomware to be able to decrypt the files using the preferred decryption tool of the attackers.
The ransom note “README.txt” stated that Kodc would encrypt the files using 265-bit AES encryption. In this type of ransomware, users are obliged to use a decryption tool, which can only be purchased from the Kodc developers for the amount of $980. The victim will have to transfer that amount to the online payment channel provided by the Kodc developers.
It is impossible to decrypt files without using the right tool. Unfortunately, in Kodc ransomware virus, only the developers or cyber criminals can have this tool. So, in order for user to decrypt the compromised files, users tend to pay the ransom to the Kodc developers.
