How Does BlackHat Ransom Virus Infect PC’s

The infection process of this ransomware virus is similar to other ransomware viruses out there. The cyber-criminals who are behind it may send massive spam messages to users, which look somewhat like the following:

The e-mails may usually have attachments in them posing as the legitimate files they are described to be, but may also contain a web link to external websites for file sharing, such as Dropbox in order to avoid blocking the e-mails from being sent.

The malicious file of the virus, responsible for the infection and encryption is reported by researchers to be the following:

BlackHat Ransomware – Malicious Activity

When the victims of BlackHat ransomware open the malicious files of the virus, the payload may be dropped onto the victim’s computer in the following Windows locations:

%AppData%
%Roaming%
%Local%
%Temp%

After the payload is dropped, the BlackHat ransomware may perform a set of activities, starting with obtaining administrative privileges. These may be used to modify the following Windows registry sub-keys adding entries in them with the location of the malicious files:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

In addition to this, the BlackHat ransomware may also delete the shadow volume copies on the infected computer, which may result in deleting the shadow volume copies of Windows via the following commands:

→ process call create “cmd.exe /c vssadmin.exe delete shadows /all /quiet & bcdedit.exe /set {default} recoveryenabled no & bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures”

In addition to this, the virus drops it’s distinctive ransom note, mocking the black hat hacking conference:

Text from note:

Your documents, photos, databases and other important files have been encrypted with strongest encryption and locked with unique key, generated for this computer.
Private decryption key is stored on a secret Internet server and nobody can decrypt your files until you pay and obtain the private key.
Caution: Removing of Blackhat will not restore access to your encrypted files.

BlackHat Ransomware – Encryption

The encryption process of BlackHat ransomware is done with the aid of the XOR encryption algorithm which is generally a strong cipher, only a bit outdated. The cipher renders important documents, audio files, videos, archives and other types of files no longer openable. The BlackHat ransomware may attack files which have the following file types:

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.
