Remove AtomSilo Virus (.ATOMSILO Files Ransomware) – Filecoder Ransomware

AtomSilo Virus Ransomware

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

The message given by AtomSilo text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the Filecoder clan. It literally mentions that the info is encrypted and that the only way to restore it is to use a a special decryption key. Sadly, this is definitely true. The kind of cryptography mechanism applied by AtomSilo is still not appropriately examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.

Another trick of AtomSilo is that the victims cannot gain access to the key. The key is stored on a specific server run by the frauds connected with AtomSilo ransomware. To get the key and recover the important info people have to pay the ransom.

Nevertheless, regardless of the asked for quantity, people need to keep away from paying the virus. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not provide any positive outcome and people just lose 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 AtomSilo ransomware and to recover the data data for free. Therefore, the just best decision is to recover the lost information from the available backup.
