844-763-5838 Scam – Technical Information

The tech support scam uses the 844-763-5838 phone number as a contact and puts into every fake alert message. That’s the reason it is called like that. This scam uses a Trojan horse to make an executable file called WinInfos.exe.

It puts it in the following directory:


Afterward, the Trojan horse creates sub-keys for that file in the Windows Registry.
These are the sub-keys:

  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\WinInfos
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\Security
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\Enum
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\WinInfos
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cWinInfos
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cWinInfos\Security
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cWinInfos\Enum

Then, new registry entries are created, to make the Trojan auto-start with the boot of the Windows operating system and to make it more resilient. Those are the registry entries:

→HKEY_LOCAL_MACHINE\SOFTWARE\cWinInfos\”version” = “”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CWININFOS\0000\”Service” = “cWinInfos”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CWININFOS\0000\”Class” = “LegacyDriver”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CWININFOS\0000\”ClassGUID” = “{8ECC055D-047F-11D1-A537-0000F8753ED1}”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CWININFOS\0000\”DeviceDesc” = “cWindows Informations Service”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CWININFOS\0000\Control\”ActiveService” = “cWinInfos”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\WinInfos\”EventMessageFile” = “%Windir%\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”Type” = “10”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”Start” = “2”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”ErrorControl” = “1”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”ImagePath” = “%Windir%\cWinInfos\168271\WinInfos.exe”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”DisplayName” = “cWindows Informations Service”
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cWinInfos\”ObjectName” = “LocalSystem”

After all of the aforementioned prerequisites are set, the executable file WinInfos.exe keeps popping up alert messages with errors. Those alerts are fake, and the goal here is to try and trick you into calling the provided phone number, which is 844-763-5838.

This is exactly how such a fake alert message looks like:
