.UIWIX Ransomware – How Does It Infect

The infection process of this ransomware virus is comprised by a mix of different tools to conduct the infection:

  • Exploits for all the SMB versions, used by WannaCry ransomware.
  • Malcious macros.
  • Infection software (Droppers, Loaders).
  • Malicious spamming software.
  • Worms or Botnet infections.
  • A pre-configured list of e-mail addresses that are spammed.

This may result in the sending of multiple different types of spammed e-mails. These spammed e-mails may include various different malicious files uploaded as e-mail attachments. The files are presented as legitimate documents in convincing messages, like the one in the example below:

Some e-mails may even contain embedded malicious macros which may pretend to allow the user to view their content after the macros have been enabled, which causes the infection:

Other methods of spreading the .UIWIX file virus may be via more sophisticated malware such as botnet infections, Trojans that have previously infected a system as well as worm infections that spread automatically from a computer to computer.

.UIWIX File Ransomware – Malicious Activity

As soon as the inevitable has happened, the loader of UIWIX ransomware drops the malicious files of the virus in various Windows folders, under different names, for example:

After the files are dropped, UIWIX ransomware obtains administrative permissions over the victim’s computer.As soon as these are obtained the virus may focus on deleting:

  • System Restore Points.
  • Windows shadow copies.

This is achievable by executing the bcedit and vssadmin commands with elevated privilege in Windows command prompt:

After this has been conducted, the ransomware may also heavily modify the Windows Registry Editor and target the Run and RunOnce registry keys, that have the following locations:

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 those keys, the UIWIX ransomware virus may create multiple different values with custom data within them that have random names.

In addition to having dropped the malicious files on the compromised computer, UIWIX ransomware also drops the ransom note In a text file, named _DECODE_FILES.txt. It has the following content:

>>> ALL YOUR PERSONAL FILES ARE DECODED <<< Your personal code: {uniqueID} To decrypt your files, you need to buy special software. Do not attempt to decode or modify files, it may be broken. To restore data, follow the instructions! You can learn more at this site: {TOR-based web page} If a resource is unavailable for a long time to install and use the tor browser. After you start the Tor browser you need to open this link {TOR URL}

The virus also redirects to a custom TOR-based web page, where after entering human verification CAPTCHA, the victim is led to the following screen:

The Encryption of UIWIX

When it comes to encrypting files, UIWIX ransomware does not mess about. The virus looks for important files and is very careful to skip system folders, like:

  • %Windows%
  • %AppData%
  • %System32%
  • %Local%
  • %LocalLow%
  • %Roaming%

Other than that, the following file types may be encrypted if your computer was infected by UIWIX ransomware:

  • Audio files.
  • Image file types.
  • Archives.
  • Virtual drive files.
  • Documents.
  • System image files.
  • Multiple video file types.

After UIWIX attacks your computer, the virus replaces blocks of data from the original files with encrypted data and then generates a unique decryption key which corresponds to that data. This key can only be obtain if the ransom of approximately 0.12 BTC is paid which is NOT ADVISABLE. After encryption, the files may appear like the following:
