Dewd was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are not able to get access to them. Dewd ransomware adds its own “.dewd” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Dewd, will be entitled as “price_list.xls.dewd”. As soon as the encryption is accomplished, Dewd puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by text file asking for the random os extremely comparable to the alerts provided by other ransomware threats coming from the DJVU family. The warning basically indicates that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.
The method to encrypt the files used by Dewd is not entirely researched. However, there is no doubt that each computer owner may be issued a special decryption key, which is definitely special. It is very hard to recuperate the data without the proper type in place.
