Protect Your Device from Meltdown Spectre Bug Attack | Apple Microsoft released Security Patches

Protection from Bug: The good news is coming to the users to protect their devices from the Meltdown and Spectre processor level flaws. The moderations from Companies including Microsoft, Apply and Chrome have been rolled out to customers to save Computers, Smartphones, Tablets from these “Meltdown” and Spectre Bugs which have been named by Researchers recently on the reveal of Google’s Project Zero Team in its new study.

Microsoft, Apple safe from Meltdown, Spectre Bug 

The Google security researchers recently highlighted the huge Security flaws in Intel, ARM & AMD Processors & alarmed the users across the globe from Meltdown and Spectre vulnerabilities which could impact billions of Computers, Smartphones, Tablets & other operating devices run on Windows, Linux, iOS, MacOS, tvOS, Android and nearly all operating systems .

The good news is that the solutions to protect the devices from these Security vulnerabilities from Bugs (Meltdown and Spectre) are available. After the Microsoft and Apple patches which have been rolled out & their claims to provide complete security to users.

Still a Big Concern:

The big concern which is still remaining in the operating system users that so many companies are involved from Chip Manufacturers to PC makers to Operating System Companies figuring out if your computer is fully protected or not and how far it will be reasonable.

Speculative Execution:

The flaws, which researchers have code-named Meltdown and Spectre, relate to how a CPU handles tasks that it thinks your PC will need to perform in the future, known as speculative execution.

What are Meltdown Bug and Spectre Bug?

Meltdown and Spectre bugs are stated as the two security flaws which may cause huge security risks in Operating Systems of Intel, ARM, AMD & other processors nearly in all Devices from PC to Smartphone. Meltdown is considered to impacts only Intel chips whereas Spectre bug can impact pretty much every known modern processor including Intel, ARM, AMD as per research made by Google. Because these processors and their architecture is commonly used on nearly on smartphones, laptops, computers, etc it means every single known device is vulnerable to these exploits.

Protect Your PC from Meltdown & Spectre Bug

1) How can I Protect my PC or Smartphone from this Meltdown or Spectre?

Protecting your device from the recently discovered bugs or security flaws has become the top priority of the Operating System companies. From Chrome OS to Window OS & iOS all companies are patching their OS’s security. Microsoft, Google, Mozilla & Apple are all issuing patches for their browsers & Operating Systems to take defense as first priority.

Microsoft Patches: Microsoft just after getting the flaws and their vulnerabilities report called the emergency patch for all Window 7,  8 to the Windows 10 inclusive and issued the security updates for Window OS users. On Window 10 Microsoft has issued automatically updates for fixing the problem. According to The Verge, check for Microsoft update KB4056892 on your Windows 10 PC. This was pushed on January 3, 2018 and should have automatically got installed on your PC. However, for Windows 7 and Windows 8 users, the updates will come on January 9, 2018. Some firmware upgrades will also to be required to protect the PC in case of WindowOS.

Microsoft is stern to provide Security to Users:

Despite of Researchers’ claim that how easy these attack works on Linux machines, but Microsoft says it has “not received any information to indicate that these vulnerabilities have been used to attack customers at this time


Apple has also released the modifications in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to give protection against Meltdown bug. Based on Reuters It will also release an update for Safari on macOS and iOS in the coming days.

Though Apple has not yet commented on how it would fix its Safari browser or even macOS.

Chrome OS:

In case of Chrome browser those who are using it will have to update to the latest version which shall release on January 23, 2018. Google Chrome 64 will contain modifications to protect against exploitation. According to the support page, ChromeOS versions prior to 63 are not patched, so those are at risk.

Firefox Browser: Firefox Browser users need to be on version Firefox 57.0.4 to ensure their protection against the Meltdown and Spectre attacks. Along with that an anti-virus software will also have to be updated against the attacks, and programs like Avast, Avira, BitDefender have pushed the fix to customers. (With Chrome OS, Google says some versions are no longer supported and these are definitely at risk).

Users Experience:

Chrome, Edge, and Firefox users on Windows won’t really need to do much apart from accept the automatic updates to ensure they’re protected at the basic browser level.

Yes Meltdown and Spectre Bug really affect Processors

The Meltdown flaw only affects Intel processors, and researchers have already released proof-of-concept code that could lead to attacks using Meltdown. Recently Google’s Project Zero Team after internal research on Security flaws studying more than a year, confirmed the design flaw vulnerabilities in Intel, ARM & AMD based CPUs, all Macs and iOS devices.

The vulnerabilities allow an attacker to compromise the privileged memory of a processor by exploiting the way processes run in parallel
