If you utilise Google Chrome extensions for business you’ll know that these handy tools can elevate your browsing experience in numerous ways, from blocking intrusive ads to minimising distractions.
Google Chrome extensions are incredibly favoured due to the functionality they bring to your browser. However, just as one must exercise caution when installing new apps on a phone, similar vigilance is necessary when adding new extensions to your browser. This is because they carry the risk of malware.
Malware, short for malicious software, is any software intentionally crafted to cause harm to a computer, server, or network. Cybercriminals employ malware to steal data, hijack systems, and even drain bank accounts.
Google Chrome commands about 65% of the global browser market share, making it the most popular browser by a significant margin. This popularity turns Chrome into an attractive target for cybercriminals. While cyberattacks can sometimes exploit vulnerabilities in the browser itself, there’s an easier method to target Chrome users: through malicious extensions containing malware.
Despite Google’s stringent monitoring of its Chrome Web Store, risks still persist. A recent report revealed that 280 million people installed a malware-infected Chrome extension between July 2020 and February 2023. This staggering number underscores the necessity of remaining vigilant.
Alarmingly, numerous malicious extensions stayed available on the Chrome Web Store for extended periods. On average, malware-laden extensions remained accessible for 380 days, while those with vulnerable code stayed up for about 1,248 days. One particularly infamous extension was available for download for an astonishing eight and a half years before being removed.
So, how can you shield yourself and your business from these malicious Google Chrome extensions? Here are five steps we recommend:
- External Reviews: Since ratings and reviews on the Chrome Web Store are not always dependable (many malicious extensions have no reviews), seek external reviews from reputable tech sites to determine whether an extension is safe.
- Permissions: Be wary if an extension requests more permissions than necessary. If a new extension demands extensive access to your data or system, this could be a warning sign.
- Security Software: Employ robust security software to catch malware before it can cause harm. This acts as your last line of defence if you inadvertently install a malicious extension.
- Necessity: Before installing any new software or browser extensions, assess whether you genuinely 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 significantly reduces the risk of downloading a harmful extension.
Chrome’s popularity means it will perpetually be a target for cybercriminals. Google’s security team diligently reviews every Chrome extension to ensure safety, but it remains crucial to stay alert.
