Windows Instrument Management (WMI) Provider Host — or WmiPrvSE.exe — is a legitimate and essential component for keeping your computer's various applications and systems running effectively. This process is part of the Microsoft Windows operating system.High CPU usage by WMI Provider Host is usually a sign that another application is requesting data through WMI. To identify the process causing high CPU usage, use the Event Viewer to find recent "Error" events and locate the process ID number.• 3y ago. The WMI Provider Host is a program that executes Windows Management Instrumentation (WMI) queries on behalf of another program. It's what actually does the work when another program wants to know info like "give me a list of programs with window title X".
Is enabling WMI a Security risk : Because WMI provides detailed information about system configuration, performance and usage, it can potentially be used to collect sensitive information about users and applications without their knowledge or consent.
What is WMI malware
Windows Management Instrumentation – T1047
The WMI service communicates by using Remote Procedure Calls (RPCs) over port 135. This service is often abused by attackers to move laterally in the network and deploy malicious commands by using the WMI cmdlet (WMIC) or executing files remotely.
What is Conhost virus : There's a particular conhost.exe virus called Conhost Miner that stores itself in this folder, and possibly others: %userprofile%\AppData\Roaming\Microsoft\ This virus attempts to run a Bitcoin or other cryptocurrency mining operation without you knowing, which can be very demanding of the memory and processor.
CPU usage going up to 100% can be caused by multiple things such as a failing hard drive, virus/malware, or software that utilizes the CPU so much.
Adversaries also use WMI for persistence via the trio of WMI event consumers, filters, and filter-to-consumer bindings. Adversaries use this persistence mechanism to execute arbitrary code in response to activity on the endpoint such as a user logging in or out or a file being written to a specified path.
