But malicious e-mails are not the only way that can help replicate this virus. The malicious files may also come onto victims’ computers as a downloaded file from what appears to be a malicious website, for example:

  • Software setup.
  • Software or games crack.
  • Pach.
  • Keygen.
  • A Driver setup.
  • Portable software or games.

.TQV Files Virus – Analysis

The TQV ransomware virus is the type of malware which has been associated with a number of malicious files dropped in various folders on the computers of victims. The virus’s main goal is to make the important files on your PC a weapon against you and hold them hostage until a ransom has been paid. To reach it’s end goal, the ransomware drops it’s main payload file, that has the following information:

→ SHA-256:d9a1afc8536fb2bb27e7155d8506baf1ff38ffd5dd12a84b50e63c94b961f553
Name:TQVRansomware.exe
Size:148 KB

The file and other files that may be complementary to it may be dropped in the following Windows directories:

  • %LocalLow%
  • %Local%
  • %AppData%
  • %Temp%
  • %Roaming%

Among the dropped files is the ransom note of TQV ransomware, which is named @@README.txt and has the following message to victims:

Your files had been encrypted Please send me $100 to get your files back

Send your information includes Security code, Computer name and Username to {e-mail}

Your security code is: {CODE HERE} After receiving password, run TQVDecrypt on your desktop to decrypt files

In addition to this, the TQV ransomware virus is also the type of infection that may modify the Windows registry sub-keys below. The modification is composed of created registry entries in different sub-keys in order to get this malware to perform different automatic activities, like run on Windows start-up or open files automatically as well.

→ 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
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

But the TQV ransomware threat does not stop there. The virus may also delete the system backups and shadow volume copies. The deletion of those usually occurs by running the following Windows Command Prompt commands as an administrator on the victim PC:

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

TQV Ransomware – Encryption Process

The encryption process of TQV ransomware has been created in order to help victims to perform a scan of the files the virus is about to encrypt. The virus aims to look for files based on their file extensions. These files are usually the following 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.
