Ldhy Virus Ransomware

Ldhy is a destructive software application working as common ransomware. Michael Gillespie, the popular virus researcher, very first discovered this new name in the DJVU ransomware family.

Ldhy was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are not able to get access to them. Ldhy ransomware includes its own “.ldhy” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Ldhy, will be titled as “price_list.xls.ldhy”. Once the encryption is accomplished, Ldhy puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The alert specified by document asking for the random os very comparable to the notifications provided by other ransomware hazards belonging to the DJVU family. The warning generally indicates that the information has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely true.

The technique to secure the files utilized by Ldhy is not entirely looked into. Nevertheless, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely special. It is extremely tough to recover the data without the appropriate key in location.

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

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

One more peculiarity of the Ldhy 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 scoundrels who have actually released the Ldhy infection into the world wide web. In order to acquire the key and restore the important information, the users are informed to connect with the scams through email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people should get in touch with the Ldhy 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 rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online scoundrels will keep their pledges, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not lead to a successful healing. So, the users may just lose their money for absolutely nothing.

Likewise, we advise you not to call the frauds as they advise. Do not transfer loan into their wallets. There are no applications that might split the Ldhy ransomware or restore the information for free. Therefore, the only proper choice is to bring back the information from possible backups (if offered).
