What is Java NotDharma ransomware? And how does it carry out its attack?
Java NotDharma ransomware is a new crypto-malware discovered mid-April 2018. It got its name due to some of its traits that are similar to the infamous Dharma ransomware though it their relation is not confirmed yet. And besides, it adds the .java extension to the files it encrypts which is why it is named Java NotDharma ransomware by security analysts in the first place.
At the time of writing, the original file used to distribute Java NotDharma ransomware is still unknown. However, as soon as it is rooted in the system, the crypto-malware will start to look for certain file types 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.

Java NotDharma ransomware appends the .java extension it the files it has encrypted. After the encryption, it will drop a ransom note named “Decrypt Instructions.txt” that contains a brief and short message:
“All of your files are encrypted, to decrypt them write us to email: [email protected]”
Victims are asked to contact the given email address ([email protected]) in the ransom note. Usually, cyber crooks demand a ransom to be paid in digital currency such as Bitcoins, Monero, and other digital currency. Once the ransom payment is sent, cyber crooks are supposed to give the decryptor to the victims. However, do not ever make this mistake as more often than not, ransomware victims are ignored by crooks after they get what they want. The best thing you could do is to eliminate the ransomware first and then try out alternative ways to recover your encrypted files.
How is Java NotDharma ransomware disseminated over the web?
Cybercrooks behind Java NotDharma ransomware relies on spam emails in distributing the malicious payload of this cryptovirus. Crooks tend to disguise the malware-laden emails to trick users into opening them and downloading the corrupted attachment. So you have to be careful in downloading email attachments no matter who they came from.
