When the file encryption is achieved, Cdqw puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.
The alert specified by document requesting for the random os very comparable to the alerts provided by other ransomware risks coming from the DJVU family. The warning basically indicates that the data has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is absolutely real.
The technique to encrypt the files utilized by Cdqw is not totally researched. Nevertheless, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely special. It is extremely tough to recuperate the data without the suitable type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Cdqw ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have actually introduced the Cdqw virus into the internet. In order to get the key and bring back the essential data, the users are informed to contact the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.
