Threat behavior


This family of threats get onto your PC through a Nullsoft Scriptable Install System (NSIS) compiled installer. They are installed with the file name %APPDATA%\okitspace\protect\pluginprotect.exe without your consent.

They are then registered as a service with the name "Protect your browser's extensions" and modify these registry entries:

In subkey: HKLM\SYSTEM\CurrentControlSet\Services\srvPlgProtect
Sets value: "Type"
With data: "dword:00000010"
Sets value: "Start"
With data: "dword:00000002"
Sets value: "ErrorControl"
With data: "dword:00000001"
Sets value: "ImagePath"
With data: "%AppData%\okitspace\protect\PluginProtect.exe"
Sets value: "DisplayName"
With data: "Protect your browser's extensions"
Sets value: "ObjectName"
With data: "LocalSystem"

They might also create the following registry subkey as part of their installation routine:

Subkey: HKLM\SOFTWARE\PluginProtect

They send this information to a remote server.
