(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.. %All Users Profile% is the common user's profile folder, which is usually C:\Documents and Settings\All Users on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\ProgramData on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit). )

Autostart Technique

This Backdoor 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\KuGouMusic
ImagePath = "%Windows%\Help\Winlogon.exe"

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

Other System Modifications

This Backdoor deletes the following files:

%Windows%\ServiceProfiles\NetworkService\AppData\Local\Microsoft\Windows\Caches\{AFBF9F1A-8EE8-4C77-AF34-C647E37CA0D9}.1.ver0x0000000000000000.db
%Windows%\Cursors\TrustedInsteller.exe
%Windows%\LastGood.Tmp
{malware file path and name}

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

Dropping Routine

This Backdoor drops the following files:

%AppDataLocal%\Microsoft\Media Player\CurrentDatabase_372.wmdb
%Windows%\Cursors\WUDFhosts.exe
%Windows%\Help\active_desktop_render.dll
%Windows%\Help\Winlogon.exe
%Windows%\Cursors\KillProcc.sys
%Windows%\Help\active_desktop_render_New.dll
%Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host\upnphost\udhisapi.dll

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

{BLOCKED}193.19

This report is generated via an automated analysis system.

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 Backdoor.Win32.ZEGOST.ANH

[ Learn More ]

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.
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.
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

Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.
