Nnll – Ransomware
Nnll is a harmful software application functioning as common ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.
Nnll was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Nnll ransomware adds its own “.nnll” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Nnll, will be titled as “price_list.xls.nnll”. Once the file encryption is achieved, Nnll puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The message mentioned by text file requesting for the random os really comparable to the alerts given by other ransomware hazards coming from the DJVU family. The caution basically shows that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
The technique to secure the files used by Nnll is not completely researched. However, there is no doubt that each computer system owner may be released an unique decryption key, which is absolutely unique. It is incredibly tough to recover the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Nnll 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 scoundrels who have actually released the Nnll ransomware into the web. In order to acquire the key and bring back the important information, the users are told to connect with the scams by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people must contact the Nnll authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so the people will get a 50% discount, therefore, the ransom amount drops down to $490.
Nnll encrypted your information, however, it might not be the only hazard on your computer. Plus, the ransomware may be concealed deep in the system. To detect and erase the risk totally, we advise you to describe the aid of GridinSoft Anti-Malware .

There is no warranty that these online crooks will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts.
