The news about the latest massive CPU vulnerabilities – Meltdown and Spectre are around the corner since May 2017. As per Google Project Zero report, this issue affected processors of Intel, AMD, and ARM. These vulnerabilities caused serious security issues in CPUs that were released after the year 1995. They affected the processor performance, provided backdoors for hackers, and much more.
Till now, issues were reported in Intel, AMD, and ARM processors and there are three variants of the issue:
|Please Note: The two critical issues also affect many devices that run operating systems, like Chrome, Mac OS, Android, and iOS. Therefore, we suggest users to take help of concerned vendors.|
Microsoft also has acknowledged these two vulnerabilities and has released several updates to help users mitigate them. According to Microsoft, they have taken the issue serious and have released patches for all the versions of Windows and cloud services offered by them. They also mentioned that they did not receive any information of attack from customers reporting these vulnerabilities.
The organization is working is working strictly with many industry partners such as chip makers, OEMs and application vendors to provide a secure platform for users. Hence, software updates are required for protecting hardware, firmware, and software.
The two critical bugs – Meltdown and Spectre are CPU hardware bugs through which attackers can get a chance to steal your crucial data from the hard drive storage. The affected hardware chips and services are:
There are many updates that are released by Microsoft to provide protection to all the users:
For detailed information about these vulnerabilities, read the following resources:
We highly recommend all the users to take following measures to protect against these two vulnerabilities.
Action 1: Turn ON automatic updates to keep your Windows device up to date.
Action 2: Install your system with latest Windows security updates. In case, you have turned ON the automatic updates, check and verify if they are installed properly or not.
Action 3: Install the applicable hardware or firmware update that is offered by the device manufacturer. All the hardware updates are device manufacturer specific and can be installed from respective websites.
|Please Note: Before you begin, make sure that the installed antivirus software is up-to-date and compatible. You can check antivirus software manufacturer’s website for the latest version compatibility information.|
You can check for enabled protection with the help of PowerShell script published by Microsoft itself. The script can be executed easily on your systems.
Launch PowerShell as Administrator on your system and run the following commands:
|PowerShell Verification using the PowerShell Gallery (Windows Server 2016 or WMF 5.0/5.1)
Install the PowerShell Module
PS> Install-Module SpeculationControl
Run the PowerShell module to validate the protections are enabled
PS> # Save the current execution policy so it can be reset
PS> $SaveExecutionPolicy = Get-ExecutionPolicy
PS> Set-ExecutionPolicy RemoteSigned -Scope Currentuse
PS> Import-Module SpeculationControl
PS> # Reset the execution policy to the original state
PS> Set-ExecutionPolicy SaveExecutionPolicy -Scope Currentuser
