On Tuesday March 16th, Microsoft released a regular Patch Tuesday update to fix two 0-day vulnerabilities in their Windows software. Microsoft has labeled the two vulnerabilities as critical and is asking users to update their systems as soon as possible.
What is a 0-Day Vulnerability?
A 0-day vulnerability is a type of security loophole that allows hackers to gain access to a system without authorization. Hackers are able to exploit the vulnerability by executing malicious code on the vulnerable system. 0-days can be very dangerous if not patched immediately.
How were the 0-Days Discovered?
The two 0-days were found by Microsoft Security researchers. These researchers are constantly on the lookout for any possible vulnerabilities that could affect the security of their users. In this case, the two 0-days were discovered in the user mode and kernel mode drivers, allowing elevation of privilege through malicious code execution. Microsoft was able to quickly identify and patch the vulnerabilities before any malicious code was able to be executed.
Why is Updating Crucial?
Updating your system is essential in order to protect against 0-day vulnerabilities. If left un-patched, malicious code can be executed, allowing attackers to gain access to your system and confidential information. Microsoft urges users to update their systems immediately in order to protect against these vulnerabilities.
What Should I Do?
If you are a Windows user, the first thing you should do is update your system. You can do this by going to your Windows Settings, selecting “Updates & Security”, and then selecting “Check for Updates”. If you do not see the updates available, you may need to download and install the patches manually. It is also important to practice good cyber hygiene by using strong passwords and two-factor authentication when possible.
Conclusion
Microsoft has fixed two 0-day vulnerabilities in their Windows software. It is important for users to update their systems immediately in order to protect against these vulnerabilities. If you have not updated your system, please do so now. Also, do not forget to practice good cyber hygiene in order to protect yourself from future threats.
