Kobos – General Info

The Kobos stands for a ransomware-type infection. Kobos was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Kobos adds the “.[ArtemisDC@keemail.me].kobos” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Kobos, will be renamed into “myphoto.jpg.[ArtemisDC@keemail.me].kobos“. As quickly as the encryption is finished, Kobos places a special text file into every folder containing the encrypted data.

The message given by Kobos text file asking for the ransom is definitely the like the statements given by other ransomware representatives. It actually discusses that the information is encrypted which the only way to bring back it is to use a a special decryption key. Regretfully, this is absolutely true. The kind of cryptography mechanism used by Kobos is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is completely unique. It is impossible to bring back the files without the key available.

Another trick of Kobos is that the victims cannot get to the key. The key is kept on a specific server run by the frauds associated with Kobos ransomware. To get the key and recover the important info people need to pay the ransom.

However, regardless of the requested quantity, people should keep away from paying the ransom virus. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not give any positive outcome and people just waste their money for absolutely nothing.

We highly encourage that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Kobos ransomware and to recover the data data totally free. Thus, the just right decision is to recover the lost data from the available backup.
