Here’s how to know if your computer is safe from the new hacking system or not.
Last Thursday, July 15, Google Chrome announces a newly-discovered ‘zero-day’ exploit in its system. This new hacking system, just like the previous zero-day attacks, was already made public before Google had a patch against it. If you want to know if your computer was compromised, here are the steps to find out.
Google Chrome’s new ‘zero-day’ attack
According to Checkpoint.com, a ‘zero-day’ attack is a specific type of software vulnerability that usually gets known by the developers after the attack. Before the companies were able to find their solution, the attack already spread out in public usage. Thus, the reason why companies like Google prevent these attacks.
Unfortunately, a new ‘zero-day’ attack was recently found again in Google Chrome. The attack is formally known as CVE-2021-30563. This was already the eighth zero-day exploit found on Google for the year 2021, and also the third attack in a month.
Since the attack is still being fixed from the Google server, there is still no information available about it. Aside from the fact that it is identified by Chrome as “Type Confusion in V8.” This type of attack usually means an “open source in the heart of Chrome.”
Should you be worried?
Other than the fact that hackers may compromise your computer by using Chrome, Google said there is nothing to worry about the new ‘zero-day’ exploit.
In fact, Chrome was not the only internet browser affected by the attack. Security Magazine also noted the appearance of Internet Explorer and Safari in the said attack. Researchers believed that all three attacks were made by a single actor.
Google’s Threat Analysis Group (TAG), the department handling the case, also speculates that the attack might come from the country Armenia. As explained, the actor sent one-time links to the target which were attacker-controlled domains. This process could mimic other original websites, leading to consumers using the hacked websites.
So far, Google promises consumers that they’re doing everything to solve the issues.
“We would also like to thank all security researchers that worked with us during the development cycle to prevent security bugs from ever reaching the stable channel,” said Google in the announcement. “Google is aware of reports that an exploit for CVE-2021-30563 exists in the wild.”
How to check if your computer is compromised?
If you’re worried about your personal data, how can you make sure you’re not affected by the said attack?
To protect yourself from the possible attack of the newly-discovered ‘zero-day’ attack, follow these steps below:
- Open your Google Settings
- Go to ‘Help’
- Find the ‘About Google Chrome’
Once you’ve done all these steps, check the data posted on your screen. If your browser version on Linux, macOS and Windows is listed as 91.0.4472.164 or above you are already safe.
If not, here are the things you should do next:
- Manually update your Google Chrome browser
- Restart your computer once the update is done
All current fixes of Google are now included on the next patch.
