Dnet Virus Removal Guide (+Decrypt .dnet files)

Dnet Virus – Details

Dnet is a harmful software functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Dnet was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the encryption is effectively achieved, the users are not able to get access to them. Dnet virus includes its own “.dnet” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Dnet, will be titled as “price_list.xls.dnet”. As soon as the encryption is accomplished, Dnet puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.

The alert stated by document asking for the random os really similar to the notifications provided by other ransomware threats belonging to the DJVU family. The warning generally indicates that the data has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The method to secure the files utilized by Dnet is not entirely looked into. However, there is no doubt that each computer owner may be issued an unique decryption key, which is definitely unique. It is very hard to recuperate the information without the suitable type in location.

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

One more peculiarity of the Dnet infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have actually launched the Dnet ransomware into the internet. In order to obtain the key and restore the crucial information, the users are informed to contact the scams by means of 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 Dnet authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so individuals will get a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their pledges, 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 frequently does not result in an effective healing. So, the users may simply lose their money for nothing.

Similarly, we urge you not to call the scams as they advise. Do not transfer loan into their wallets. There are no applications that could crack the Dnet virus or bring back the data at no charge. Therefore, the only proper decision is to bring back the information from possible backups (if available).
