Technical Information

To ensure autorun and distribution

Creates the following services

[<HKLM>\System\CurrentControlSet\Services\bklqicvp] 'Start' = '00000002'
[<HKLM>\System\CurrentControlSet\Services\bklqicvp] 'ImagePath' = '%WINDIR%\SysWOW64\bklqicvp\wjvslydn.exe /d"<Full path to file>"'
[<HKLM>\SYSTEM\CurrentControlSet\services\bklqicvp] 'ImagePath' = '%WINDIR%\SysWOW64\bklqicvp\wjvslydn.exe'

Malicious functions

To complicate detection of its presence in the operating system,

adds antivirus exclusion with following registry keys:

[<HKLM>\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths] '%WINDIR%\SysWOW64\bklqicvp' = '00000000'

Executes the following

'%WINDIR%\syswow64\netsh.exe' advfirewall firewall add rule name="Host-process for services of Windows" dir=in action=allow program="%WINDIR%\SysWOW64\svchost.exe" enable=yes>nul

Injects code into

the following system processes:

%WINDIR%\syswow64\svchost.exe

Modifies file system

Creates the following files

%TEMP%\wjvslydn.exe
%WINDIR%\syswow64\config\systemprofile:.repos

Moves the following files
