What is Cdtt file virus

Actually it is just another Ransomware from the STOP Ransomware family. It is one among many others like Cdwe, Cdaz, Cdqw, Cdmx which have terrorized computer users recently. When this nasty malware intrudes on your computer, it encrypts all your files.

Once infected, Cdtt Ransomware will encrypt all your important files by adding its own malicious .Cdtt extension to the end of all your file names. For instance, if you have any file with the name “image.jpg” then it will be converted to “image.jpg.cdtt”. This new extension to the end of all your file names means that you can’t access those files.

Cdtt File Virus

Victims will find the ransom note called “_readme.txt” file in all your folders. The ransom note is used to demand ransom money and contains all the details about the encryption. On this note, .Cdtt extension virus demands $980 to decrypt your files. The main purpose of this nasty Cdtt Ransomware virus is to scare users and extort their money by taking their files hostage.

Ransom Note Shown By Cdtt File Virus

As you can see in the image, the ransom note attacks victims psychologically. It starts with the phrase Don’t worry, you can get your files back and then it states that all your files are encrypted with a unique key and strongest encryption. Furthermore, it also claims that the only way to decrypt your files is by purchasing its decryption tool and unique key. However, this is not true. The older version of Stop Ransomware encryption has been cracked by security experts.

Furthermore, to prove its decryption tool works, Cdtt File Virus agrees to decrypt a single file for free. The ransom note also mentions that victims who contact the operators of Cdtt Ransomware within the first 72 hours of encryption will get 50% off. In simple words, if you contact the hackers in the first 72 hours after encryption you will only need to pay $490 instead of $980.

Well, $490 is still a lot to pay but in comparison with $980, it’s always a better deal. So if you notice how hackers play with victims’ psychology, creating a sense of urgency in their minds, and not giving them enough time to process things, think it through. However, it is highly advised not to rush your decision. You are dealing with hackers and hence you should be very careful.

What Types of Files Cdtt Virus Encrypt

This nasty malware infection can encrypt a wide range of file types. In other words, it can lock down almost every type of file that a person can store on his/her computer including pictures, documents, videos, audio, screenshots, word, PDF, etc. The main motive of Cdtt File Virus is to force users to pay ransom money so hackers cover all the bases to ensure that users can’t ignore them.
