What is TBlocker ransomware? And how does it carry out its attack?
TBlocker ransomware is a file-encoding Trojan designed to encrypt files to make them inaccessible to its victims. TBlocker ransomware spreads as a malicious executable file named TBlocker.exe which was caught spreading online since February 2018. Once it is able to get a hold of a targeted computer, it alters the Windows Registry to boot with system startup, inject malicious codes into system processes as well as install other malicious files to perform other tasks in the system. In addition, it also scans the system for certain kinds of files to encrypt such as:
.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.
