Cdtt Virus Removal Guide (+Decrypt .cdtt files)

Cdtt – Ransomware

Cdtt is a malicious software application working as common ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.

Cdtt was developed for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively accomplished, the users are not able to get access to them. Cdtt ransomware adds its own “.cdtt” to all the encrypted files. For instance, the file “price_list.xls”, once modified by Cdtt, will be entitled as “price_list.xls.cdtt”. Once the file encryption is achieved, Cdtt puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The alert stated by _readme.txt requesting the random os very similar to the notices given by other ransomware threats coming from the DJVU family. The warning essentially shows that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The approach to encrypt the files used by Cdtt is not completely looked into. Nevertheless, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely special. It is extremely tough to recover the information without the proper key in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Cdtt ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually released the Cdtt virus into the web. In order to get the key and restore the crucial information, the users are told to get in touch with the frauds through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people must call the Cdtt authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so individuals will get a 50% discount rate, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom frequently does not result in a successful healing. So, the users may simply lose their money for nothing.

Similarly, we advise you not to get in touch with the scams as they advise. Do not transfer money into their wallets. There are no applications that could split the Cdtt virus or bring back the information at no charge. Therefore, the only proper choice is to restore the information from possible backups (if available).
