Trojan.Madominer Coin Miner Virus – Analysis

When the Trojan.Madominer has infected a certain computer, the virus creates the following folders:

→ %System%\Tasks\GooglePinginConfigs

Then, the Trojan.Madominer drops it’s malicious files on the victim PC and they could have the following names and locations:

→ %ProgramFiles%\stormii\server.exe
%SystemDrive%\[PATH TO MALWARE]\[MALWARE ROOT]\tem.vbs
%System Drive%\IIS\CPUInfo.exe
%System Drive%\IIS\Doublepulsar-1.3.1.exe
%System Drive%\IIS\Esteemaudit-2.1.0.exe
%System Drive%\IIS\Esteemaudittouch-2.1.0.exe
%System Drive%\IIS\Eternalblue-2.2.0.exe
%System Drive%\IIS\Eternalchampion-2.0.0.exe
%System Drive%\IIS\free.bat
%System Drive%\IIS\s.bat

But the virus does not stop there as it creates a lot of tasks and registries to kill different executables that belong to Windows and to run exectuables that perform the mining process as an administrator without them being bothered. Symantec report the following registy values to be created:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\1.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\2.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\3.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Systmss.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\csrss..exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\nanol.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\svchostr.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\wax.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\wuauc1t.exe\”debugger” = “taskkill.exe”
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ystmss.exe\”debugger” = “taskkill.exe”

Next, the Madominer Trojan could download additional miner files from several suspicious domains, that end in .com:3 and .info:3. The virus also remotely connects to 8 different servers that end in .info which help it relay the cryptocurrency mining information and begin the mining process.

The malware also has a worm function enabled, meaning that it could propagate to other PCs in the same network and could possibly create copies of it’s infection files to be spread via USB and other removable drives connected to the infected computer in question.

If you suspect that the Madominer Trojan is installed on your PC, do not underestimate it and remove it ASAP. If the Trojan stays for long time on your PC, it may do a lot more than just mine for cryptocurrencies, like Monero and BitCoin at your computer resources’ expense. The virus may also perform spyware activities, such as:

  • Obtain your keystrokes via a keylogger program.
  • Steal different types of files and folders directly from your drive.
  • Take screenshots from your desktop.
  • Steal passwords.
  • Steal camera and audio communication and record it.
