Drugvokrug727 Virus – Methods of Distribution

The Drugvokrug727 ransomware virus probably has more than one distribution method. Targeted attacks are surely one of the main methods, as well as spam email campaigns. A spam email will try to engage you into reading it and opening a file attached to that email. The attachment may seem harmless and of known file type, but in reality to be the payload source for the ransomware. Be extremely careful around emails that have attachments or download links in their body.

Platforms and websites of that kind might distribute the malicious payload code with executables or batch files, disguised as necessary and useful software applications. An important advice you could follow to prevent ransomware viruses from infecting you is to avoid every email, file or link that seems suspicious and is of an unknown origin. Refrain from directly opening files in general – check their signatures, size and possibly scan them with a security program.

Drugvokrug727 Virus – A Closer Look

Drugvokrug727 is how a virus has been dubbed, belonging to the Shade/Troldesh ransomware family a.k.a. the XTBL ransomware. The name of this virus is derived from the email that its creator uses for contact – Drugvokrug727@india.com. As other ransomware viruses of the same family, this one also puts that email in the extension of each encrypted file.

Here are more variants of this ransomware virus:

The ransomware will encrypt files found on your hard disk drives or other storage devices, but system files will not be touched. Before the encryption process begins, the ransomware goes through some predefined stages. After the ransomware finds an entry point to your computer and its payload file is executed, the malicious script found inside will initiate the following:

First, it will create five files, some of which are executables and some contain instructions:

%UserProfile%\How to decrypt your files.jpg

%System%\[THREAT FILE NAME].exe

%UserProfile%\Start Menu\Programs\Startup\[THREAT FILE NAME].exe

%UserProfile%\Start Menu\Programs\Startup\How to decrypt your files.jpg

%UserProfile%\Start Menu\Programs\Startup\How to decrypt your files.txt

Second, it will create this entry in the Windows Registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\”[RANDOM CHARACTERS]” = “%System%\[THREAT FILE NAME].exe”

That registry entry will keep the ransomware virus perseverant and launch it with every start of the Windows Operating System.

Third, it will then connect to a remote location, which may be one of the following:
  • jfheubdh.cc
  • kurvilkazz.ru
  • rrpproxy.net
  • dd24.net
  • key-systems.net
  • keydrive.lu
  • avtomoika234.cc
  • tuginsaat.com

Next, your files get encrypted, and after that process is complete, you will notice your desktop background to be swapped with some new wallpaper. That wallpaper contains instructions about how to contact the ransomware makers. Also, in the picture, there is a famous movie character portrayed – The Dude from the movie “The Big Lebowski”. That is how your desktop will look like if you got infected:

That picture on your desktop and a text file with instructions bear the name How to decrypt your files. The text on the image shown above reads:

Дектиптор файлов можно
получить на почте:
drugvokrug727@india.com

Decryptor files are available
at the post office:
drugvokrug727@india.com

The other file – How to decrypt your files.txt looks like this:

The Drugvokrug727 virus does not specify a payment price for the decryption of your files. Also, it does not urge you with a limited time period. The ransomware creator has left only a single email for contact, which the ransomware is named after by researchers.

Do NOT even try to contact the Drugvokrug727@india.com email or any other alternative email address you could have been provided with from the virus. Even if you pay the ransom, you may not get your files back. See this comment posted in our blog by a user infected with ransomware of the same family. The user paid a fortune and didn’t get the courtesy of getting even a single file back.

So, paying criminals will technically make you their accomplice, as the money will be used to further their criminal activities. Also, because Drugvokrug727 is one of the many variants of the Shade/Troldesh ransomware family, there is a way you can try to restore your files. A decryptor tool manufactured by Kaspersky exists, and you can see it in the instructions below this article.

When all files get encrypted, you will notice that the files will have this extension appended to them – .id-[eight digit number]-drugvokrug727@india.com.xtbl.

Afterward, the ransomware will send the following information to a remote location:

Trojan ID
Compromised computer ID
Host name
Email address used by the Trojan
Number of encrypted document, archive, database, and image files
