Critical updates for Windows 7 to 11 to fix latest threats

Ransomware warning on laptop

Like Google, Microsoft Windows operating systems remain under cyber threat for quite some time.

Windows is an easy-to-use operating system that is widely adopted across the globe. Recently, it’s reported that new security flaws have made Windows users wonder about their data protection.

Although, Windows 7 was rolled out by Microsoft initially now Microsoft doesn’t support it. This means, there will be no security fixes for Windows 7 users. All they’ve to do is to look for some reliable data backup and recovery service to keep their data protected.

Importantly, Windows 7 isn’t supported by known anti-viruses, therefore, they’ll have a weak defense against cyber attackers. This is why Windows Operating systems are the most targeted OS across the globe.

A lot of manufacturing, logistics, medical, critical infrastructures companies still use an old version of Windows because their systems (managing and monitoring software) are not compatible with the new versions of Windows.

Therefore, people who’re still using the older operating system are in danger of huge data breaches. Salvador supports immediate recovery solutions for Windows 7, 8, 10, and 11. Keeping this in view, Microsoft has released the latest critical update for Windows to Windows 11 OS users to fix the latest security threat.

The Critical security update was rolled out on all Windows versions to ensure rapid fixes. gHacks has revealed vulnerabilities in the latest Patch Day and issued a warning to the Windows 7, 8, 10, 11, and all Windows Server editions to download the bug fixes before it gets too late.

Apparently, Microsoft has restricted all information about the new hacks just to give some time to its Windows users. However, the company has pointed to the exact location of vulnerabilities and termed the hacking attempts as “Critical” level threats.

Top Vulnerabilities

Microsoft has mentioned the following security flaws along with their patch links on the official website:

  • Critical – CVE-2021-43233 – all Windows versions, Remote Desktop Client Remote Code Execution Vulnerability.

  • Critical – CVE-2021- 43217 – All Windows versions, Windows Encrypting File System (EFS) Remote Code Execution Vulnerability.

  • Critical – CVE-2021- 43215 – All Windows versions excluding Windows 11, Windows Server 2022, SNS Server Memory Corruption Vulnerability Can Lead To Remote Code Execution.

Note: You can find the patch link on the original Microsoft Website.

All the above-mentioned vulnerabilities allow cyber hackers to get access to the Windows versions and help them in remotely launching malicious code. The CVE-2021-43215 gets a 9.8 score out of 10 in Microsoft’s Exploitability Index.

Microsoft has rolled out fixes for all three bugs to Windows users. However, the quickest and easiest way to protect yourself is to click on the Patch links and choose your Windows version.

The security research Abdelhamid Naceri discovered one of the failed patches and warned users,

“You better wait and see how Microsoft will screw the patch again”

He was right as Microsoft has rolled security patches rather than creating an official fix to ensure user protection. This means Windows users will need to install the security patches and wait for something to happen either positive or negative.

Keeping this in view, Salvador technologies has devoted itself to helping resolve data protection issues of windows users. With cyber recovery software, we help our clients by taking periodic backups of their important data to recover when needed.

This helps us in reducing the downtime of our client’s network. Our ransomware prevention techniques use advanced technology to counter cyber-attacks effectively.

Loopholes in Patches

Microsoft claims to have delivered patches for all bugs in its operating systems. The initial patches were able to fix issues for quite some time but the botched patches result in a massive security hole in all Windows versions.

Attackers will easily make use of that security hole to exploit users' data and create a powerful impact as compared to the previous one. Later the company released an unofficial patch to ensure that users have enough time to secure them while the company gets a permanent solution.

The security hole allows hackers to right-off all privileges to get access to everything in the target computer. This helps them in spreading the malicious code across the victim’s entire network.

Microsoft stated,

“We are aware of the disclosure and will do what is necessary to keep our customers safe and protected.”

How To Install The Fix?

To fix the abovementioned bugs, you’ll have to register yourself for the Opatch account. Then, you need to install the download agent of Opatch.

The best thing about Opatch is that it’s focusing on becoming a go-to solution for Windows users. Most experts predicted that Opatch will help Windows Users to fix all three bugs and that’s what happened when Microsoft announced to use of an unofficial patch.
