What is .Fs0ciety file extension virus?

.fs0ciety file extension virus is just another name for the infamous FS0CIETY ransomware, which has been discovered in the beginning of October 2016. This ransomware variant seems to be inspired by the popular Mr.Robot drama series about a hacker boy. This real-life virus encrypts files with unique AES cipher, then encodes the encryption key with RSA cryptography. As a result, the user becomes unable to access personal files. Such virus puts the computer user to an unenviable situation, because it takes away precious memories (pictures, videos, etc.), and also important documents and presentations that the user might need for his work or studies. The ransomware wants to extort money from the victim, so it creates fs0ciety.html file on the desktop, which is widely known as the ransom note. This ransom note contains information about the encryption, and explains how to pay the ransom.

Another virus that can append .Fs0ciety file extensions to encrypted data is known as Fs0ci3ty ransomware virus. It uses AES-256 CBC to encrypt victim’s files, and it means that files become modified on a structural level and cannot be opened, edited, or used in any way. This virus appends file extensions to encrypted files, and as you can see, the new file extension contains an e-mail address that is also provided in the ransom note. The ransom note waves hello to the victim with a line “Welcome to Fs0ci3ty” and says that the victim has to pay 1.5 Bitcoins in order to get the decryption software that can restore encrypted data to the initial condition. In case victim decides to delay the payment, the ransom increases by 1 Bitcoin daily.

Unfortunately, it is not yet known whether frauds related to .Fs0ciety file extension viruses actually provide the decryption tool if the victim follows their commands and pays the ransom. We do not encourage computer users to pay ransoms because there are numerous cases proving that criminals do not provide the decryption software after receiving the ransom. Therefore, we believe that you should think twice before paying the ransom to cyber criminals – these people are definitely not the ones you can rely on. If you decide not to pay the ransom, remove .Fs0ciety virus without a delay with a powerful anti-malware software, for instance, ReimageIntego. You might need to reboot your PC into a Safe Mode with Networking first to be able to launch the anti-malware software. If you do not know how to do that, follow .Fs0ciety removal instructions given below the article.

How to shield your computer from ransomware attacks?

Ransomware is a filthy virus and it uses advanced techniques to enter the victim’s computer. The history of ransomware shows that the most successful method to enter the target computer is to send a bogus email letter containing the malicious executive file to the owner of the computer. As soon as the victim opens such email attachment, the computer gets infected. Sometimes, ransomware viruses spread with the help of other malware, for instance, Trojans. If the machine has been infected with such malicious program before, the victim can see no signs of its presence, until it downloads such aggressive malware like ransomware on the system. Finally, ransomware can be installed along fake software updates, for example, Flash updates. Do not agree to install such updates from websites that obviously do not belong to the developer of Flash Player!

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
