Protect Your Business from Malicious Chrome Extensions
If you use Google Chrome in your business, you're likely familiar with extensions. These handy tools can enhance your browsing experience, from blocking annoying ads to reducing distractions.
The Popularity and Risk of Extensions
Extensions are popular because they add significant functionality to your browser. However, just as you must be cautious when installing new apps on your phone, you need to be careful when adding new extensions to your browser due to the risk of malware.
Malware, short for malicious software, is designed to damage computers, servers, or networks. Cybercriminals use malware to steal data, hijack systems, and even empty bank accounts.
With Google Chrome holding about 65% of the global browser market share, it’s a prime target for cybercriminals. While some cyber attacks exploit browser vulnerabilities, an easier method is through malicious extensions containing malware.
The Reality of Malicious Extensions
Despite Google's vigilance over its Chrome Web Store, risks remain. A recent report revealed that 280 million people installed malware-infected Chrome extensions between July 2020 and February 2023. This alarming number underscores the need for vigilance.
Shockingly, many malicious extensions remained available on the Chrome Web Store for extended periods. On average, malware-filled extensions stayed up for 380 days, while those with vulnerable code were available for about 1,248 days. One notorious extension was downloadable for eight and a half years before removal.
How to Protect Yourself and Your Business
To safeguard against malicious extensions, follow these five steps:
1. External Reviews: Check ratings and reviews from trusted tech sites rather than relying solely on the Chrome Web Store. This can help you gauge the safety of an extension.
2. Permissions: Be wary if an extension requests excessive permissions. Extensive access to your data or system could be a red flag.
3. Security Software: Use robust security software to catch malware before it can cause harm. This acts as your last line of defense.
4. Necessity: Consider whether you truly need the extension. Often, you can achieve the same functionality by visiting a website.
5. Trusted Sources: Only install extensions from trusted sources or well-known providers to reduce the risk of downloading harmful extensions.

Chrome’s popularity makes it a constant target for cybercriminals. While Google’s security team works diligently to review every extension, staying vigilant is essential.
