Kodg Virus Removal Guide (+Decrypt .kodg files)

Kodg Virus – Details

Kodg 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.

Kodg was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the file encryption is successfully accomplished, the users are unable to get access to them. Kodg ransomware adds its own “.kodg” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Kodg, will be titled as “price_list.xls.kodg”. When the encryption is achieved, Kodg puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The message stated by document requesting for the random os really similar to the notices provided by other ransomware risks belonging to the DJVU family. The caution basically indicates that the information has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The method to encrypt the files utilized by Kodg is not completely researched. However, there is no doubt that each computer system owner may be released an unique decryption key, which is definitely unique. It is incredibly difficult to recuperate the information without the suitable type in location.

“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 Kodg ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually released the Kodg virus into the internet. In order to acquire the key and bring back the essential information, the users are told to contact the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that individuals need to get in touch with the Kodg authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so the people will acquire a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no guarantee that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom typically does not result in a successful healing. So, the users may just lose their money for nothing.

Likewise, we urge you not to get in touch with the frauds as they instruct. Do not transfer loan into their wallets. There are no applications that could break the Kodg ransomware or bring back the data for free. Therefore, the only appropriate decision is to bring back the data from possible backups (if offered).
