Is that Chrome extension filled with malware?

If your business relies on Google Chrome, you’re likely familiar with extensions—those handy tools that can enhance your browsing experience by blocking ads, improving productivity, or reducing distractions.

While extensions are popular for adding valuable functionality, it’s essential to be cautious when installing them. Just like apps on your phone, browser extensions can pose security risks, including malware.

Malware, short for malicious software, is designed to harm your computer, server, or network. Cybercriminals use it to steal data, take control of systems, and even drain bank accounts.

As the most widely used browser, with around 65% of the global market share, Chrome is a major target for cyberattacks. While some attacks exploit vulnerabilities in Chrome itself, a simpler method is through malicious extensions.

Although Google works hard to keep its Chrome Web Store secure, risks remain. In fact, a recent report revealed that between July 2020 and February 2023, 280 million users installed Chrome extensions that were infected with malware. This staggering number highlights the importance of being vigilant.

Shockingly, many of these malicious extensions remained available for long periods. On average, malware-laden extensions stayed on the Chrome Web Store for 380 days, and extensions with vulnerable code were accessible for about 1,248 days. One infamous example was available for over eight years before it was removed.

So, how can you protect your business from these harmful extensions? Here are five key steps:

1. External reviews: Ratings and reviews on the Chrome Web Store may not always be reliable, as some malicious extensions fly under the radar. Check trusted tech websites for external reviews before installing any new extension.

2. Permissions: Be wary if an extension asks for more permissions than it should. If it’s requesting extensive access to your data or system, consider it a red flag.

3. Security software: Use robust security software to catch malware before it can cause damage. This provides a critical safety net in case you accidentally install a malicious extension.

4. Necessity: Before adding a new extension, ask yourself if you really need it. Often, you can achieve the same functionality by visiting a website rather than installing extra software.

5. Trusted sources: Stick to extensions from reputable developers or well-known software providers. This significantly reduces the risk of downloading harmful extensions.

As Chrome continues to be a major target for cybercriminals, it’s important to stay vigilant. While Google works diligently to review and secure extensions, it’s ultimately up to you to protect your business.
