Corona-Lock Virus – Details

The Corona-Lock mean a ransomware-type infection. Corona-Lock was elaborated specifically to encrypt all major file types. When the file is encrypted people are not able to use them. Corona-Lock adds the “.corona-lock” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Corona-Lock, will be renamed into “myphoto.jpg.corona-lock“. As soon as the encryption is completed, Corona-Lock places a special text file into every folder containing the encrypted data.

The message given by Corona-Lock text file asking for the ransom is absolutely the like the statements given by other ransomware representatives. It actually points out that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The kind of cryptography mechanism used by Corona-Lock is still not appropriately examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is absolutely distinct. It is difficult to bring back the files without the key available.

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