Noos – General Info
Noos is a malicious software application functioning as typical ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.
Noos was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Noos ransomware includes its own “.noos” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Noos, will be titled as “price_list.xls.noos”. As soon as the file encryption is achieved, Noos puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by text file requesting the random os really similar to the notices given by other ransomware dangers coming from the DJVU family. The caution essentially shows that the files have been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.
The method to secure the files utilized by Noos is not entirely looked into. However, there is no doubt that each computer owner may be issued a special decryption key, which is definitely special. It is extremely tough to recuperate the data without the suitable type in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Noos 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 total control by the crooks who have launched the Noos ransomware into the web. In order to acquire the key and restore the important data, the users are informed to connect with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.
The message also says that individuals need to contact the Noos authors within 72 hours upon the minute of the information file encryption. The alert shows that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount falls to $490.
No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online crooks will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom frequently does not lead to a successful healing. So, the users may merely lose their money for nothing.

There are no applications that could crack the Noos ransomware or bring back the data at no charge. For that reason, the only appropriate decision is to bring back the information from possible backups (if available).
