Kodc Virus Removal Guide (+Decrypt .kodc files)

Kodc Virus – Details

Kodc is a destructive software functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.

Kodc was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Kodc virus includes its own “.kodc” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Kodc, will be titled as “price_list.xls.kodc”. Once the encryption is achieved, Kodc puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The alert specified by document asking for the random os really similar to the alerts offered by other ransomware threats belonging to the DJVU family. The warning basically indicates that the data has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The technique to encrypt the files utilized by Kodc is not totally investigated. Nevertheless, there is no doubt that each computer owner might be released an unique decryption key, which is definitely unique. It is exceptionally tough to recover the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Kodc infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have launched the Kodc infection into the world wide web. In order to acquire the key and bring back the important information, the users are informed to connect with the frauds via email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people need to get in touch with the Kodc authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so the people will get a 50% discount rate, therefore, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly encourage that you do not pay the ransom. There is no assurance that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom often does not result in a successful recovery. So, the users might merely lose their money for absolutely nothing.

Likewise, we advise you not to contact the scams as they instruct. Do not move money into their wallets. There are no applications that could split the Kodc ransomware or restore the information for free. Therefore, the only correct choice is to restore the data from possible backups (if offered).
