It actually points out that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Karla404 is still not appropriately examined. Still, it is definitely specific that each victim may be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.

Another technique of Karla404 is that the victims cannot get to the key. The key is saved on a particular server run by the frauds connected with Karla404 ransomware. To get the key and recover the important information people have to pay the ransom.
