Grod Virus Removal Guide (+Decrypt .grod files)

Grod Virus Ransomware

Grod is a destructive software working as common ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.

Grod was developed for the sole function to encrypt all popular file types. Logically, as soon as the encryption is successfully achieved, the users are unable to get access to them. Grod ransomware includes its own “.grod” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Grod, will be titled as “price_list.xls.grod”. As soon as the file encryption is accomplished, Grod puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The message stated by _readme.txt requesting for the random os extremely similar to the notifications provided by other ransomware risks coming from the DJVU family. The warning essentially shows that the files have been secured and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The method to secure the files utilized by Grod is not completely investigated. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely special. It is incredibly hard to recuperate the data without the suitable type in place.

“Don’t worry, you can return all your files!”, from text file message:

message from Grod virus

One more peculiarity of the Grod virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually launched the Grod ransomware into the internet. In order to acquire the key and restore the important information, the users are informed to get in touch with the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals ought to call the Grod authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so the people will get a 50% discount rate, therefore, the ransom amount falls to $490.

There is no guarantee that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom frequently does not result in an effective recovery. So, the users may merely lose their money for nothing.

There are no applications that could crack the Grod virus or bring back the information at no cost. For that reason, the only proper decision is to restore the data from possible backups (if offered).
