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.
AtomSilo encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.
