Cdwe was developed for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Cdwe ransomware adds its own “.cdwe” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Cdwe, will be titled as “price_list.xls.cdwe”. When the encryption is achieved, Cdwe puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The alert specified by _readme.txt requesting for the random os very comparable to the notices offered by other ransomware dangers coming from the DJVU family. The warning generally shows that the files have been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.
The method to encrypt the files utilized by Cdwe is not entirely looked into. Nevertheless, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely distinct. It is exceptionally hard to recover the information without the proper key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Cdwe virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually released the Cdwe infection into the web. In order to acquire the key and restore the important information, the users are told to connect with the frauds through email or by telegram and to pay the ransom in the amount of $980.
The message also states that the people should contact the Cdwe authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so the people will get a 50% discount rate, therefore, the ransom amount falls to $490.
