Ewdf virus adds its own “.ewdf” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Ewdf, will be titled as “price_list.xls.ewdf”. Once the file encryption is accomplished, Ewdf puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.
The message specified by _readme.txt requesting the random os really comparable to the notices given by other ransomware hazards belonging to the DJVU family. The warning essentially shows that the data has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.
The technique to secure the files utilized by Ewdf is not entirely looked into. However, there is no doubt that each computer system owner might be issued an unique decryption key, which is definitely distinct. It is extremely difficult to recover the data without the appropriate type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Ewdf 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 introduced the Ewdf virus into the web. In order to obtain the key and restore the important information, the users are informed to contact the scams by means of email or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people ought to call the Ewdf authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so individuals will get a 50% discount, for that reason, the ransom amount drops down to $490.
