Google has introduced an update to the Chrome browser and released a second patch within a month that fixes five vulnerabilities, including a zero-day vulnerability. One of the most important bugs can be traced as CVE-2021-21193 and affects the Windows, Linux, OS X versions of the browser.
This vulnerability was detected by an anonymous user, and through this bug an attacker can execute arbitrary code on the target system. The measuring of this error is 8.8 out of 10 on the CVSS scale. To avoid this security issue, update your Google Chrome browser at Settings -> Help -> About.
Why the browsers?
Browsers tend to evolve faster in many organizations than other applications, and browsers are a great way to reap the benefits, and attackers continue to target them because they continue to be excellent entry points for endpoint threats within the organization. In addition, the extensions are usually updated less frequently and require hardening to prevent further attacks.
What is a zero-day vulnerability?
Timing is most important here. The moment the flaw becomes known, hackers around the world can try to exploit it. Overall, programmers have zero days to find a solution to the issue, henceforth the term “zero-day vulnerability”.
This can take almost any form, such as missing data encryption, buffer overflows, missing permissions, SQL injection, broken algorithms, URL redirects, errors, or password security issues.
How protect yourself?
Here are some tips to help protect your business from these types of attacks:
• Be informed: pay attention to software vendor spending, it may be time to take advantage of security measures or respond to threats before taking advantage of them
• Take additional security measures: consider seeking the assistance of an experienced professional, as the safety measures mentioned above are not sufficient to fully protect you.
• Keep your system up to date: make sure your software platforms are up to date. The best solution is to allow automatic updates so that the software is updated regularly without any manual intervention.
