Rzfu Virus – Details

Rzfu was developed for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are unable to get access to them. Rzfu ransomware adds its own “.rzfu” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Rzfu, will be entitled as “price_list.xls.rzfu”. When the file encryption is achieved, Rzfu puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by document asking for the random os very comparable to the notifications provided by other ransomware dangers coming from the DJVU family. The caution essentially shows that the information has been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.
The approach to secure the files used by Rzfu is not entirely investigated. However, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely distinct. It is very hard to recover the data without the proper key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Rzfu 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 crooks who have actually introduced the Rzfu virus into the world wide web. In order to obtain the key and bring back the crucial data, the users are told to contact the scams by means of 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 Rzfu authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so the people will get a 50% discount rate, therefore, the ransom amount falls to $490.
