Nuksus – General Info
Nuksus is a harmful software working as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.
Nuksus was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Nuksus virus adds its own “.nuksus” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Nuksus, will be entitled as “price_list.xls.nuksus”. Once the file encryption is achieved, Nuksus puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.
The message mentioned by text file requesting for the random os extremely comparable to the alerts provided by other ransomware threats belonging to the DJVU family. The caution essentially indicates that the data has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.
The approach to encrypt the files utilized by Nuksus is not completely looked into. Nevertheless, there is no doubt that each computer owner may be issued an unique decryption key, which is absolutely distinct. It is very difficult to recover the information without the proper type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Nuksus infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have actually released the Nuksus infection into the world wide web. In order to obtain the key and restore the essential information, the users are told to connect with the frauds via email or by telegram and to pay the ransom in the quantity of $980.
The message also states that the people ought to contact the Nuksus authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so individuals will acquire a 50% discount, therefore, the ransom amount drops down to $490.
