Check your browser! These malicious extensions have been installed 1M times

Browser extensions enhance your online experience. They can help with translations, conversions, spellchecking, shopping and blocking popup ads. They allow you to customize your browsing experience and can even change the way websites look. Dark mode is one example of a popular extension.

But not all extensions are safe. You’re giving them access to lots of information, such as contact details. While some extensions store this data for convenience, others use it to track you or launch cyberattacks. We recently reported on malicious Chrome extensions downloaded 1.4 million times.

We have some bad news. 30 more extensions put your privacy at risk. Here’s what they do and what you can do about it.

Have you heard of malvertising?

Security researchers at Guardio Labs uncovered a campaign of malicious extensions with millions of installations worldwide. The “Dormant Colors” extensions offer browser customization, particularly changing the colors.

At least 30 variants of the extension were found available for free in the Chrome and Edge stores. They were installed more than a million times.


You may think you’re getting some excellent tools to change the look of your browser, but what you’re getting is malware.

When you run a search, the extensions hijack your results and send you to pages with affiliate advertising. The developers make money off your clicks and views this way.

Dormant Colors also adds affiliate links to the URL of pages you visit. The scammers get a commission if you buy something on that site.

Here’s a list of the malicious extensions:

  • Action Colors.
  • Background Colors.
  • Power Colors.
  • more styles.
  • Nino Colors.
  • Change Color.
  • More Styles.
  • Dood Colors.
  • Super Colors.
  • refrech color.
  • Mix Colors.
  • imginfo.
  • Mega Colors.
  • WebPage Colors.
  • Get colors.
  • hex colors.
  • what color.
  • soft view.
  • Single Color.
  • border colors.
  • colors scale.
  • colors mode.
  • style flex.
  • Xer Colors.

How to remove extensions from Google Chrome

The extensions have been removed from the official stores, but they may still be installed on your machine. Here’s how to find and remove the harmful extensions:

  • Open Chrome and click the three vertical dots at the top right.

  • Once you find an extension you want to delete, click Remove and Remove again.

Google Chrome’s Safety Check scans your account for compromised passwords and available updates. It also turns on Safe Browsing, a setting that identifies unsafe websites and notifies you of potential harm.

  • Select Settings > Privacy and security from the left panel.
