There is more than one distribution method that may be associated with the .tfude ransomware. The virus infects by two main infection objects:

  • Malicious files disguised as legitimate ones.
  • Web links that the victim is either redirected to or clicks on.

If the infection with the .tfude ransomware virus commences via malicious files, it may be done in the following ways:

  • Via e-mail that is sent to the victim, which disguises the e-mail attachments as legitimate documents, like invoices, recepts, etc.
  • Via the malicious file being uploaded online and pretending to be a setup of a program or patch, crack and other forms of license activation executables.

If the infection commences via a malicious web links, this is usually done as a result of a JavaScript code that is malicious and aims to infect users as a result of getting them to click on fake buttons or the links themselves. In some cases, the crooks may use an adware or another program that may cause browser re-directions and infect your computer with the .tfude ransomware automatically.

In addition to this, the .tfude ransomware virus may also begin to modify the Windows Registry Editor of the infected computer by adding registry values in Windows. These values are often focused on automatically running the ransom note and the encryption module of the ransomware. They may be located in the Run and RunOnce sub-keys of the Winbdows Registry Editor as shown below:

→ 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 modifying the Registry Editor, the .tfude ransomware virus may also delete the shadow copies of the infected computer. This is done to eliminate any chances of using Windows Recovery service to restore previous versions of your files. To do this, the .tfude ransomware may execute the following commands in an Administrator command prompt:

→sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

.tfude Ransomware – Encryption Process

When it comes down to encrypting files of victims, the .tfude ransomware has clever scanning features. The malware skips all of the important Windows files and directories, but it scans for and encrypts any:

  • Audio files.
  • Videos.
  • Images.
  • Documents.
  • Backup file types.
  • Virtual drives.
  • Virtual signatures.
  • Banking files.

The virus does this with the main goal of getting victims to still be able to use their computer to pay the ransom. In addition to this, the .tfude ransomware uses the combination of AES and RSA encryption algorithms, which is typical for most ransomware viruses. The .tfude virus may encrypt the files, using the AES cipher and then lock the encryption key with the RSA-1024 encryption algorithm. After encryption, .tfude ransomware adds the .tfude file extension to the encrypted files and they assume the following appearance:
