Lltt – General Info

Lltt is a malicious software working as typical ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.

Lltt was created for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is effectively achieved, the users are not able to get access to them. Lltt virus adds its own “.lltt” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Lltt, will be entitled as “price_list.xls.lltt”. As soon as the encryption is achieved, Lltt puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by text file requesting the random os really comparable to the notices given by other ransomware threats coming from the DJVU family. The caution generally indicates that the files have been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

The technique to encrypt the files used by Lltt is not completely looked into. Nevertheless, there is no doubt that each computer owner might be released an unique decryption key, which is absolutely special. It is exceptionally difficult to recuperate the data without the proper key in location.

One more peculiarity of the Lltt 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 crooks who have released the Lltt infection into the world wide web. In order to acquire the key and bring back the crucial information, the users are informed to contact the scams via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals must call the Lltt authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so individuals will obtain a 50% discount, 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 assurance that these online criminals will keep their promises, 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. For this reason, paying ransom often does not lead to an effective healing. So, the users may merely lose their money for nothing.

There are no applications that could break the Lltt virus or bring back the information at no charge. For that reason, the only correct decision is to bring back the information from possible backups (if offered).
