What is BlackHat ransomware? And how does it implement its attack?
BlackHat ransomware is a file-encrypting virus created to encrypt valuable data in an infected computer and extort money from victims. The first activity of this threat was first reported at the beginning of November 2018. It connects a targeted computer to a remote C&C server where it downloads additional malicious components and places them on system folders. After the infiltration, it collects various data in the system. The data collected is then processed and used to scan the system for any digital signature of AV programs, sandbox environment, and so on. Once it finds the aforementioned programs, BlackHat ransomware either disables them or removes them from the system to keep them from interrupting the attack.
In addition, BlackHat ransomware also makes alterations in the Windows Registry in order to run automatically on every system boot. It will most likely modify the RunOnce keys. After the modifications, BlackHat ransomware will look 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.

Once it finds its targeted files, BlackHat ransomware will encrypt them using the AES encryption algorithm. After data encryption, it appends .BlackHat extension to all the affected files and releases a ransom note in a file named “ReadME-BlackHat.txt” which contains the following message:
“All your data has been locked us. Do you want to return? Contact to Email:
[email protected] or ID Telegram: @C3NTER Your Personal KEY: [base64 key]”
