Data Recovery ToolWindows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

Shujin Ransomware – Spread

To be widely redistributed over the web, this particular crypto-malware may use a variety of methods. The most frequently met distribution tactics used by ransomware are the following:

  • Infection via malicious URLs posted on spam e-mail messages, social media messages and commends and chat messages.
  • Infections via redirects to malicious drive-by URLs caused by PUPs, for example, DNS Unlocker.
  • Distribution of the malicious files via obfuscated processes, pretending to be setups of programs or torrent files that users search for online for free download.

Whatever the method may be, once this ransomware is on your computer, it may execute scripts that enable it to slip onto the PC undetected by security software.

Shujin Ransomware In Detail

Once executed, the ransomware may deploy its malicious files in key windows folders. The folders vary, since the file formats may also vary. For example, if the modules for encryption it uses are .tmp files, they are usually dropped In the %Temp% folder. The names of the malicious files may also vary. Here are the common paths and filenames that Chinese Ransomware may utilize to infect your device:

commonly used file names and folders

After dropping its files, the ransomware may tamper with several key registry entries in the Windows Registry Editor. Users who have been infected by Chinese Ransomware should check the following registry entries:

→ HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\User Shell Folders
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Shell Folders] HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServices
HKEY_LOCAL_MACHINE\Software\CLASSES

After this is done, Chinese ransomware may execute a “call” script to launch the encryption process. It may scan through the infected to a computer for some of the most commonly used file types. After scanning the files are encrypted with the “.txt” file extension, for example:

→ Photo.jpg.txt

After the files are encoded they are unable to be opened and instead, users come to see a text file. Renaming the extension back to normal is reported not to help, pointing out to all of the files being rendered unusable.

Unlike other ransomware, this ransomware displays its message completely in Chinese. Here is how the message appears and to what it translates:
