Hello! This plugin is designed to impove stealth of Windows VM while analyzing malware.
KUSER_SHARED_DATA.TickCountandKUSER_SHARED_DATA.TickCountMultiplierfields;IWbemServices::ExecQueryto spoof WQL-queries to WMI objects that aren't present on VM. Name of the requested object is overwritten toWin32_BIOSwhich is alway presented. It is done to bypass checks like in al-khaser project (https://github.com/LordNoteworthy/al-khaser/blob/06399c26a488c1bbdea29fe2023cf5360b640bb7/al-khaser/AntiVM/Generic.cpp#L1673)MSAcpi_ThermalZoneTemperatureobject is requested to check current temperature.
