In this article I will try to help you remove Kodc ransomware for free. Also I will assist you in decoding your crypted files.

What is “Kodc”?

Kodc can be correctly identify as a ransomware infection.

Kodc is similar to other the same family: Piny, Redl, Mkos. It crypted all popular file types. Hence, users cannot open the your documents or photos. Kodc adds its own “.kodc” extension into all files. For instance, the file “video.avi”, will be changed into “video.avi.kodc”. As soon as the encryption is successfully accomplished, Kodc creates a special text file “_readme.txt” and puts it into all folders that contain the modified files.

Here is a short info for the Kodc ransomware:

This text asking payment is for restore files via decryption key:

The scary alert demanding from users to pay the ransom to decrypt the compromised data contains these frustrating warnings

The cryptography algorithm used by Kodc is AES-256. So, if your documents got encrypted with a specific decryption key, which is totally distinct and there are no other copies. The sad reality is that it is impossible to restore the information without the unique key available.

In case if Kodc worked in online mode, it is impossible for you to gain access to the AES-256 key. It is stored on a remote server owned by the criminals who distibute the Kodc ransomware.

For receiving decryption key the payment should be $980. To obtain the payment details the victims are encouraged by the message to contact the frauds by email (gorentos@bitmessage.ch), or via Telegram.

Do not pay for Kodc!

Please, try to use the available backups, or Decrypter tool

_readme.txt file also indicates that the computer owners must get in touch with the Kodc representatives during 72 hours starting from the moment of files where crypted. On the condition of getting in touch within 72 hours users will be granted a 50% rebate, thus the ransom amount will be minimized down to $490). Yet, stay away from paying the ransom!

I definitely recommend that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.

The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t really perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main PC is surely not a wise idea.

Kodc has a various methods to built into your system. But it doesn’t really matter what concrete way had place in your case.
