What is Seon ransomware? And how does it carry out its attack?
Seon ransomware is yet another file-encrypting threat designed to lock important files in a computer. This crypto-malware was first initially discovered way back in October but appeared again on November 14, 2018. It uses the .FIXT extension in marking the files it infects and demands a ransom in BTC for file recovery. Based on the analysis done on its source code, Seon ransomware does not originate from any ransomware groups. It also revealed that this ransomware may be released as test samples which mean that its updated versions might use an even more complex infection pattern.
Once it invades a computer, Seon ransomware will employ several modules in the system. The first one is the data gathering module which obtains sensitive information from the system and later on uses it for the second module called stealth protection. This second module scans the computer for any security programs that could interfere with its attack and prevents it from doing so by bypassing the real-time engines or by completely deleting them.
Seon ransomware also makes changes in the Windows Registry so that it can automatically run on every system startup, making it a persistent threat. After these changes, it then scans the computer for files with the following extensions:
.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.

After it finds its targeted files, Seon ransomware encrypts them using the AES encryption algorithm. Following data encryption, it appends the .FIXT extension to every affected file and releases a file named “YOUR_FILES_ARE_ENCRYPTED.txt” which contains the following content:
all your files has been encrypted
