If you're concerned about your device being vulnerable to ZombieLoad attacks, explore the following article by Mytour to learn effective methods to protect your device from ZombieLoad attacks.
1. ZombieLoad Vulnerability
ZombieLoad vulnerability allows attackers to pilfer data such as private browsing history, passwords, and other information on the victim's computer by exploiting hardware vulnerabilities in Intel.
Also known as CVE-2018-12130, ZombieLoad exploits existing vulnerabilities in how CPUs handle 'Zombie Loads'—data that the processor cannot handle correctly, necessitating the use of the processor's microcode to prevent mishandling. This payload may contain sensitive data from applications and programs, and the ZombieLoad vulnerability enables access to this information.
2. How to Check if Your Device is Affected by ZombieLoad?
Unfortunately, there is currently no way to determine if your device is affected by the ZombieLoad vulnerability. Moreover, antivirus and internet security software cannot detect this vulnerability.
If your device uses an Intel chip manufactured before 2011, the risk of being affected by ZombieLoad attacks is extremely high.
In other words, PCs, Macs, or tablets equipped with Intel chips are susceptible to attacks. To ensure the safety of your device and protect it from ZombieLoad attacks, the only solution at this time is to use AMD or ARM chips.
Although the risk of being impacted by ZombieLoad attacks is substantial, it doesn't guarantee your device will be targeted. Refer to the following content to learn how to shield your device from ZombieLoad attacks.
3. How to Protect Your Device from ZombieLoad Attacks
Method 1: Protecting your Android device from ZombieLoad attacks
Most Android devices using ARM chips won't be affected by ZombieLoad attacks. However, for devices using Intel chips, Google advises installing security patches as soon as possible.
These patch updates are provided by the hardware manufacturers of Android devices, not by Google. You can visit the official website or contact the manufacturer to find and install the latest security patches.
Alternatively, you can check for available updates using the traditional method. On your Android device, open the Settings app, go to System, and look for the latest updates.
Method 2: Safeguarding your PC against ZombieLoad attacks
ZombieLoad primarily targets Windows desktops and laptops, mainly because most of these devices are equipped with Intel chips. The vulnerability can affect devices running Windows 7 and Windows X, as well as Windows 10.
Good news is, Microsoft has released security updates for Windows 10 and older Windows versions to protect user devices from ZombieLoad attacks.
Although Windows 10 will automatically download updates, for assurance, you can check by typing 'Windows Update' into the Search bar on the Start Menu and select Check for updates. Here, find, download, and install the latest updates if available.
Method 3: Safeguarding your Mac from ZombieLoad attacks
Mac is also a victim of ZombieLoad attacks. Apple has released the ZombieLoad vulnerability patch for macOS Mojave 10.14 for all Mac and MacBook models released since 2011. Additionally, this patch includes updates for the Safari browser.
However, the performance of some Mac machines may decrease by up to 40% if all patches are applied. Additionally, Apple has released a separate security update for Macs running macOS Sierra and macOS High Sierra. iPhones and iPads are not affected.
Mac users running older macOS versions can check the Mac App Store for updates to install for OS X or the latest macOS. Users are advised to install the latest macOS versions to avoid being affected by ZombieLoad attacks.
Method 4: Safeguarding your Linux PC from ZombieLoad attacks
Apart from Windows and macOS, the ZombieLoad vulnerability also affects Linux computers equipped with Intel chips. Greg Kroah-Hartman has released Linux Kernel 5.1.2 and advises users to upgrade to the latest kernel version to avoid falling victim to ZombieLoad attacks.
Additionally, other Linux distributions are impacted by the vulnerability. Specifically, Red Hat has announced that Red Hat Enterprise Linux (RHEL) versions 5 through the latest version, v8, as well as Red Hat Virtualization and Red Hat OpenStack, are all affected by the flaw.
The company has released security kernel updates for the affected distributions, so make sure you have installed the latest updates. However, users are cautioned that these patches may cause performance issues.
Canonical, the company behind the renowned Ubuntu Linux distribution, has also released documentation on how to prevent and mitigate the impact of ZombieLoad attacks.
Method 5: Shielding your Chromebook from ZombieLoad attacks
If you are using recent Chromebook devices, you can rest assured as Chrome OS will automatically update, and the latest version - Chrome OS 74 - disables Hyper-Threading to prevent the ZombieLoad vulnerability.
Method 6: Safeguarding Firefox and Chrome browsers from ZombieLoad attacks
Mozilla has announced that it is actively researching and developing a long-term fix for the Firefox browser on macOS. The Firefox Beta and Firefox Nightly versions have already been equipped with the latest bug fixes.
If you are using Google's Chrome browser, the search giant advises users to update to the latest operating system versions (Windows, Linux, or macOS) to mitigate and prevent potential attacks.
This Mytour article has just guided you through some ways to protect your device from ZombieLoad attacks. Additionally, if you have any inquiries or questions, readers can leave their comments below the article, and Mytour will address your concerns as soon as possible.
