Cts1 was developed for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Cts1 virus adds its own “.cts1” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Cts1, will be titled as “price_list.xls.cts1”. As soon as the file encryption is accomplished, Cts1 puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.
The message mentioned by _readme.txt asking for the random os extremely similar to the notices offered by other ransomware dangers belonging to the DJVU family. The caution essentially indicates that the information has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.
The technique to secure the files utilized by Cts1 is not completely looked into. However, there is no doubt that each computer system owner may be issued a special decryption key, which is definitely unique. It is extremely tough to recover the data without the suitable type in place.

One more peculiarity of the Cts1 ransomware is that the users are not able to get access to the key.
