  • %System%\svchost.exe -k netsvcs
  • %System%\svchost.exe

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.. %Fonts% is the Windows Fonts folder, which is usually C:\Window\Fonts on Windows 2000(32-bit), XP, Server 2003(32-bit), Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.. %System Root% is the Windows root folder, where it usually is C:\ on all Windows operating system versions.)

It creates the following folders:

  • %Windows%\ServiceProfiles\NetworkService\AppData\Local\Microsoft

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

Autostart Technique

This Coinminer registers itself as a system service to ensure its automatic execution at every system startup by adding the following registry entries:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\clr_optimization_v3.0.50727_32
ImagePath = "%Windows%\Microsoft.NET\Framework\mscorsvws.exe"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\KuGouMusic
ImagePath = "%Windows%\Help\Winlogon.exe"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\KillProcc
ImagePath = "%Windows%\Cursors\KillProcc.sys"

Other System Modifications

This Coinminer deletes the following files:

  • %Windows%\Cursors\TrustedInsteller.exe

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

It adds the following registry entries:

Dropping Routine

This Coinminer drops the following files:

  • %Windows%\Cursors\WUDFhosts.exe
  • %Windows%\Help\active_desktop_render.dll
  • %Windows%\Cursors\KillProcc.sys
  • %Windows%\Help\Winlogon.exe

  SOLUTION

Minimum Scan Engine:

9.850

Step 1

Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.

Step 2

Identify and terminate files detected as Coinminer.Win32.MALXMR.TIAOODDJ

[ Learn More ]
  1. Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here.
  2. If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps.
  3. If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps.

Step 3

Delete this registry value
