What is .Java File Extension ransomware? And how does it carry out its attack?
.Java File Extension ransomware is identified to be the newest addition to the Dharma/Crysis ransomware group. This new variant uses .java file extension in marking its encrypted files. It also adds a unique identification number on the encrypted files. It mostly targets user-generated files, which according to security experts, are the files with the following formats:
.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.

Just like its predecessors, the .Java File Extension ransomware uses the AES encryption algorithm to corrupt the files it targets. Following its encryption, the victims are asked to pay a ransom in exchange for the decryptor by contacting the cyber criminals through the given email address which is [email protected]. But contacting these crooks is definitely not advised as they would only extort you more money to recover your files. The thing is if you pay these crooks, there’s actually no guarantee that they will do their end of the bargain once they got their hands on the ransom money. Crooks are proven to ignore their victims once they get what they want. So it’s better if you don’t waste both your time and money with these outlaws as there are other ways you can recover your files without losing your money.
