Mr. Robot TV series has become the inspiration for malware writers to create a ransomware, called Fsociety. The virus aims to imitate a fictional hacking group from the famous TV series, just like Anonymous is. As much as we enjoy hearing new Mr. Robot news, this one is unfortunate, because the Fsociety ransomware uses an extremely strong encryption algorithm, called AES (Advanced Encryption Standard) to encrypt the files of users. Everyone who has been infected by this threat should read this article to learn how to remove the Fsociety crypto-virus and try to restore encrypted files by it.

Fsociety Ransomware – How Does It Spread
Fsociety Ransomware – More Information
Similar to Mr. Robot’s second season, Fsociety ransomware, uses strong encryption to hold the files of the victim’s computer hostage until a ransom payoff has been completed. When executed, Fsociety ransomware may drop it’s files in different places and under different names. The most often chosen names by malware writers are:
In addition to that, Fsociety ransomware is based on the EDA2 ransomware project which is an open source ransomware code uploaded online and created by Utku Sen. Since then, many variants of the EDA2 project have popped up, because all it takes is someone who knows coding to take this source code and design own version of ransomware, just like Fsociety ransomware variant is.
As soon as the Fsociety ransomware has infected a computer, it may begin encrypting files. The Fsociety virus may be pre-programmed to scan for a wide variety of file extensions which it encrypts. Some of those files may be the following:

The encrypted files are enciphered with a powerful AES (Advanced Encryption Standard) encryption and the decryption key for them has been encoded in an RSA (Rivest-Shamir-Adleman).
The encrypted decryption key is then sent to the cyber-criminals’ command and control server where they have it along with a unique identification number for every user PC they have infected. After this, the wallpaper of the infected computer is changed to the famous Fsociety logo from the TV series Mr. Robot.
While the inspiration of the malware writers led them to choose a good TV series to base their ransomware on, this threat is one of the worse you can see out there. However, no matter how dire and bad the situation is, malware researchers advise users not to pay any ransom money if they see a ransom note asking them to contact the crooks for a payoff. This is due to several obvious reasons:
- You support the cyber-criminals by paying the ransom.
- There is no guarantee that you are going to get your files back.
Remove Fsociety Ransomware and Restore the Encoded Files
The ransomware virus should be removed by following the instructions after this article. Since Fsociety may modify the Windows Registry Editor and in addition to this create multiple files in different locations, malware researchers advise using an advanced anti-malware program to remove it, since it will make sure it is permanently remove without any damage to the encrypted files.
To restore files encrypted by Fsociety ransomware, users are strongly advised to make sure they backup the encrypted files and make copies if they try direct decryption. We have provided some alternatives to try and restore your files in step “3.Restore files encrypted by Fsociety Ransomware” below and advise you to take a look at them. They may not be 100 percent effective but in case you are lucky, haven’t reinstalled your OS and had backups, they may work for you.
