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
The creators of the Fsociety ransomware may use a different set of tools to replicate this virus. They may purchase spamming software that may distribute malicious URLs that may infect users using a JavaScript and drive-by-downloads by simply clicking on the URLs. Such URLs may be distributed in different ways, like referral spam, for instance. In addition to this, Fsociety ransomware may spread via malicious e-mail attachments, that are spam e-mails or phishing ones. The files may look like legitimate Microsoft Office documents. However, they are nothing like such, since they are disguised to get affected users to open them.
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:
→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

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.
