Google Chrome is an undisputed leader in the world of browsers, used by millions of people daily for its speed, compatibility, and ease of use . However, as technology has advanced, concerns about the privacy and security of users' personal data have also multiplied.
Many users rely on Chrome to manage passwords, sync information, and personalize their web experience. However, cybersecurity experts point out that this convenience could come at a cost: the extensive collection of information about each user's online activity , including searches, location, and even purchases or video views. This data is primarily used to personalize advertising and improve Google services, often without the user being fully aware of the extent of this collection.
Recent serious threats and vulnerabilities in Chrome
In recent months, privacy concerns in Chrome have resurfaced due to several worrying incidents. An investigation by Koi Security revealed that several popular Chrome and Edge extensions contained malware , allowing hackers to track user activity and even access sensitive data such as emails and banking information. Among the extensions flagged were Unlock YouTube VPN and Unlock TikTok, which had over two million installations and raised concerns about the reliability of security measures in official app stores.
The most worrying aspect is that these add-ons bypassed Google and Microsoft's security filters , demonstrating that even downloading extensions from "official" sources doesn't guarantee complete protection. Therefore, experts recommend regularly reviewing installed extensions, removing any that aren't essential, and only using extensions from trusted developers with verified reputations.
In addition, Google recently acknowledged a critical security vulnerability (identified as CVE-2025-6558) affecting the browser's ANGLE and GPU components. This vulnerability has been classified as "severe" because it could be exploited by visiting a malicious website, allowing unauthorized code to be executed. To protect against this flaw, it is essential to update Chrome to version 138.0.7204.157 or higher on Windows, macOS, and Linux, or the equivalent version on Android via the Google Play Store.
The importance of installing security patches cannot be underestimated, because, although Google implements advanced systems, each new vulnerability poses a real risk to the privacy and integrity of the data stored in the browser.
How does Chrome affect your privacy and what can you do?
Chrome, by design, centralizes a large amount of personal information . Beyond browsing history, it stores passwords, website preferences, locations, and syncs all this data across devices using your Google account. Although there are configuration options to limit data collection, the default settings tend to prioritize automatic collection and syncing.
Even when using incognito mode , some activity can be tracked and saved by Google, as several independent analyses have shown. Therefore, if privacy is a priority, experts suggest reconsidering using Chrome as your primary browser or, at the very least, carefully adjusting your privacy settings and disabling syncing when it's not strictly necessary.
Extensions also represent a critical point in data protection. Installing only those that are essential and completely trustworthy, avoiding granting excessive permissions, and always keeping your browser updated are key steps to prevent leaks and attacks.
If you have any concerns about the security of your passwords stored in Chrome, remember that the built-in password manager allows you to view and manage them, but it's not without risk if your device is compromised or if a malicious extension gains access to that information.
Alternatives and tips for safer browsing
For those who want greater control over their privacy, Firefox is highly recommended, as it uses its own engine and is focused on limiting ad tracking. Safari , on the other hand, offers significant protection on Apple devices. Additionally, there are emerging browsers like Ladybird and solutions like DuckDuckGo and Brave, geared towards secure, tracking-free browsing.
Beyond changing your browser, you can adopt certain best practices recommended by experts :
- Turn off automatic account syncing if you don't need it.
- Review extension permissions and remove non-essential ones.
- Always update your browser and any add-ons to the latest version.
- Use alternative search engines that are less data-driven.
- Consider using a separate password manager.
Chrome, despite its leadership, reflects the current complexities of internet privacy. Its broad ecosystem and the advantages it offers are accompanied by significant challenges for protecting personal data. Staying informed, reviewing settings, and adopting best practices are essential measures for enjoying a safer browsing experience.
