In today’s era of constant connectivity and digital dependence, browser extensions have become indispensable tools for enhancing our online experience. However, as with most technology, there is a dark side. According to a recent report by BleepingComputer, some Chrome extensions have the potential to steal plaintext passwords directly from websites. Here’s what you need to know:

What’s the Risk?

BleepingComputer’s analysis reveals that malicious Chrome extensions can access and extract plaintext passwords from web forms, such as login pages. This means that when you enter your credentials on a website, a compromised extension can capture this data before it is encrypted for transmission, putting your personal and financial data at risk.

How Does It Work?

Chrome extensions, by design, have the ability to interact with web content. Some extensions require permissions to read and modify the content of web pages for their intended functionality. In the hands of malicious actors, this permission can be misused to script and extract data from websites, including login credentials.

Since they function as intended (e.g., ad blockers, VPNs), users may not be immediately aware that their data is being stolen.
  2. Widespread Usage: Chrome, being the most popular web browser, has millions of extensions available. This makes it challenging for Google to monitor and vet every single one for potential security threats.
  3. Ease of Distribution: Malicious extensions can be spread through various means, including compromised download links or even through the official Chrome Web Store if they pass initial reviews.

How Can You Protect Yourself?

  1. Vet Extensions Carefully: Before adding any extension, research its origins. Check reviews, look for reputable publishers, and be wary of newly released extensions with few users.
  2. Limit Permissions: Only grant permissions that are absolutely necessary for the extension’s functionality. If an extension asks for broad or unrelated permissions, consider it a red flag.
  3. Regularly Review Extensions: Periodically check and clean out your installed extensions. Remove those you no longer use or find suspicious.
  4. Stay Updated: Ensure that your browser and all extensions are regularly updated. Developers often release security patches for known vulnerabilities.
  5. Use Password Managers: They can auto-fill credentials without you having to type them, reducing the risk of malicious extensions capturing keystrokes.
