Copa Virus Removal Guide (+Decrypt .copa files)

Copa – Ransomware

Copa is a malicious software working as common ransomware. Michael Gillespie, the widely known malware researcher, first discovered this new name in the DJVU ransomware family.

Copa was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is effectively accomplished, the users are unable to get access to them. Copa virus includes its own “.copa” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Copa, will be entitled as “price_list.xls.copa”. As soon as the encryption is achieved, Copa puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The message mentioned by _readme.txt requesting the random os extremely comparable to the alerts offered by other ransomware risks coming from the DJVU family. The warning generally indicates that the data has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The approach to secure the files utilized by Copa is not entirely looked into. However, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely special. It is exceptionally tough to recover the information without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

message from Copa virus

One more peculiarity of the Copa infection is that the users are not able 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 Copa virus into the internet. In order to get the key and restore the essential information, the users are informed to connect with the frauds via email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people need to contact the Copa authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so the people will obtain a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we strongly recommend that you do not pay the ransom. There is no assurance that these online criminals will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom frequently does not lead to an effective healing. So, the users might simply lose their money for nothing.

Likewise, we urge you not to contact the frauds as they instruct. Do not move loan into their wallets. There are no applications that might crack the Copa virus or restore the information at no cost. For that reason, the only correct choice is to bring back the data from possible backups (if available).
