Is Your Chrome Extension Safe? Beware of Hidden Malware!
If your business uses Google Chrome, you’re likely familiar with extensions. These handy tools can significantly enhance your browsing experience, from blocking annoying ads to reducing distractions.
Extensions are incredibly popular because they add so much functionality to your browser. However, just as you need to be cautious when installing new apps on your phone, you must be careful when adding new extensions to Chrome. They come with a risk of malware.
Malware, short for malicious software, is designed to cause damage to a computer, server, or network. Cybercriminals use it to steal data, hijack systems, and even empty bank accounts.
With Google Chrome holding about 65% of the global browser market share, it is the most popular browser by far. This makes Chrome a prime target for cybercriminals. While some attacks exploit vulnerabilities in the browser itself, malicious extensions are an easier way to target Chrome users.
Despite Google’s vigilant monitoring of the Chrome Web Store, risks persist. A recent report claims 280 million people installed malware-infected Chrome extensions between July 2020 and February 2023. This highlights the importance of being cautious.
Surprisingly, many malicious extensions remained available for download for long periods. On average, malware-filled extensions stayed up for 380 days, while those with vulnerable code were available for about 1,248 days. One particularly notorious extension was downloadable for 8.5 years before removal.
How can you protect yourself and your business from these malicious extensions? Here are five steps we recommend:
- External Reviews: Since ratings and reviews on the Chrome Web Store can be unreliable, look for external reviews from trusted tech sites to judge an extension’s safety.
- Permissions: Be cautious if an extension asks for more permissions than it should. Extensive access requests could be a red flag.
- Security Software: Use robust security software to catch malware before it can do any harm. This acts as your last line of defense if you accidentally install a malicious extension.
- Necessity: Before installing any new software or browser extension, consider whether you really need it. Often, the same functionality can be achieved by visiting a website.
- Trusted Sources: Only install extensions from trusted sources or well-known software providers. This reduces the risk of downloading harmful extensions.
Chrome’s popularity means it will always be a target for cybercriminals. While Google’s security team works hard to review every Chrome extension, it’s still crucial to remain vigilant.
