Dehd is a destructive software application functioning as common ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.

Dehd was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Dehd virus adds its own “.dehd” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Dehd, will be titled as “price_list.xls.dehd”. As soon as the file encryption is accomplished, Dehd puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The message specified by document requesting for the random os really similar to the notices offered by other ransomware risks coming from the DJVU family. The warning essentially indicates that the data has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.
