Is Your Chrome Extension a Gateway for Malware? Here's How to Stay Safe

July 26, 2024

In today's business world, Google Chrome extensions have become indispensable. They enhance your browsing experience, blocking annoying ads and reducing distractions. However, while these tools offer many benefits, they also come with potential risks, specifically the risk of malware.

Malware, short for malicious software, is designed to harm your computer, server, or network. Cybercriminals use it to steal data, hijack systems, and even drain bank accounts. With Google Chrome dominating 65% of the global browser market, it has become a prime target for such attacks. While some cyber threats exploit vulnerabilities within the browser itself, a more straightforward method involves malicious extensions.

Despite Google's rigorous monitoring of the Chrome Web Store, the risk remains. A recent report revealed that 280 million users installed a malware-infected Chrome extension between July 2020 and February 2023. This staggering number underscores the need for caution.

Shockingly, many malicious extensions remained available for a significant period before removal. On average, these harmful extensions were up for 380 days, while those with vulnerable code stayed for about 1,248 days. One particularly infamous extension was downloadable for an astonishing 8.5 years before being taken down.

How can you safeguard your business from these malicious extensions? Here are five essential steps:

1. Seek External Review: While ratings and reviews on the Chrome Web Store can be unreliable, external reviews from trusted tech sites offer a more accurate assessment of an extension's safety.
2. Scrutinize Permissions: Be wary if an extension requests more permissions than necessary. Extensive access to your data or system could be a red flag.
3. Use Security Software: Robust security software can catch malware before it causes harm, serving as your last line of defence against malicious extensions.
4. Evaluate Necessity: Consider whether you truly need a new extension. Often, the desired functionality can be achieved by visiting a website.
5. Trust Only Reputable Sources: Installing extensions from trusted sources or well-known software providers significantly reduces the risk of downloading harmful extensions.

Given Chrome's popularity, it will always be a target for cybercriminals. While Google's security team works diligently to review extensions, it's crucial to remain vigilant.
