COPAN Virus Removal Guide (+Decode .COPAN files) – DCRTR-WDM Ransomware

COPAN – General Info

The COPAN stands for a ransomware-type infection. The virus comes from the DCRTR-WDM ransomware family. COPAN was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. COPAN adds the “.COPAN” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by COPAN, will be renamed into “myphoto.jpg.COPAN“. As soon as the encryption is completed, COPAN places a special text file into every folder containing the encrypted data.

The message given by COPAN text file requesting the ransom is definitely the like the statements given by other ransomware representatives coming from the DCRTR-WDM family. It actually mentions that the info is encrypted and that the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism applied by COPAN is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.

Another trick of COPAN is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds related to COPAN ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, regardless of the asked for amount, people must keep away from paying the virus. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people simply waste their money for absolutely nothing.

We strongly advise that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack COPAN ransomware and to recover the information data totally free. Thus, the only right decision is to recover the lost data from the available backup.
