Intel Exploit January 2018

In the first week of January 2018, Google discovered two flaws which threaten almost all PCs, laptops, tablets, and smartphones, regardless of manufacturer or operating system. 

The flaws, which take advantage of the same basic security vulnerability in those chips, could hypothetically be used by malicious actors to "read sensitive information in the system's memory such as passwords, encryption keys, or sensitive information open in applications. In addition, the flaws could be exploited on servers and in data centers and massive cloud-computing platforms such as Amazon Web Services, Microsoft Azure, or Google Cloud. 

In order for them to work, both vulnerabilities require malicious code to already be running on your system, therefore it's vital to practice good online safety behaviors. The first and most important thing you should do is make sure you're up-to-date with your security patches. 

Patches are already being rolled out but they come at a price. Be aware that older PCs will have their performance slowed down by these patches.

For Atera users, we recommend running the following update. 

The following are PowerShell scripts that automatically install KB4056892 on your Windows 10 endpoints:

Install KB4056892 update on Windows 10 32 bit via PowerShell:

$url = "http://download.windowsupdate.com/d/msdownload/update/software/secu/2018/01/windows10.0-kb4056892-x86_delta_45f3a157eb4b4ced11044f6c462f21ec74287cb5.msu"
$filename = "KB4056892.msu"
$client = New-Object System.Net.WebClient

$client.DownloadFile($url, "$env:temp\$filename")
$Arg = "/quiet"
Start-Process -FilePath "$env:temp\$filename" -Argumentlist $Arg

Install KB4056892 update on Windows 10 64 bit via PowerShell:

$url = "http://download.windowsupdate.com/c/msdownload/update/software/secu/2018/01/windows10.0-kb4056892-x64_delta_d810a354692261ccaef351e06ba0bdecd194013d.msu"
$filename = "KB4056892.msu"
$client = New-Object System.Net.WebClient

$client.DownloadFile($url, "$env:temp\$filename")
$Arg = "/quiet"
Start-Process -FilePath "$env:temp\$filename" -Argumentlist $Arg

#You may add a reboot command at the end of the script, as the update requires a reboot:

Restart-Computer -force

 

In order to run the script on multiple agents through Atera, follow the steps below:

1. Go to Admin > Scripts and click on Create Script.
