Staying Safe with Google Chrome Extensions: A Guide for Businesses
If your business uses Google Chrome, you're probably familiar with the array of extensions available. These handy tools can enhance your browsing experience in numerous ways, from blocking intrusive ads to minimizing distractions.
Extensions are extremely 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 also be wary when adding new extensions to your browser due to the risk of malware.
Malware, short for malicious software, is any software intentionally designed to cause damage to a computer, server, or network. Cybercriminals use malware to steal data, hijack systems, and even drain bank accounts.
Google Chrome dominates the browser market with a 65% share worldwide, making it a prime target for cybercriminals. While cyber attacks can exploit vulnerabilities in the browser itself, a more straightforward method targets Chrome users through malicious extensions containing malware.
Despite Google's diligent monitoring of the 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 staggering number underscores the need for vigilance.
Surprisingly, many malicious extensions remained available on the Chrome Web Store for an extended period. On average, malware-filled extensions were up for 380 days, while those with vulnerable code stayed up for about 1,248 days. One particularly notorious extension was downloadable for 8 and a half years before its removal.
To protect yourself and your business from these malicious extensions, follow these five steps:
External Reviews: Since ratings and reviews on the Chrome Web Store can be unreliable (many malicious extensions lack reviews), seek external reviews from trusted tech sites to determine if an extension is safe.
Permissions: Be cautious if an extension requests more permissions than necessary. If a new extension asks for extensive access to your data or system, consider it a red flag.
Security Software: Employ robust security software to catch malware before it can cause harm. This acts as your last line of defense if you accidentally install a malicious extension.
Necessity: Before installing any new software or browser extensions, evaluate whether you truly need it. Often, you can achieve the same functionality 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.
Given Chrome's popularity, it will always be a target for cybercriminals. Although Google's security team works tirelessly to review every Chrome extension to ensure safety, it’s crucial to remain vigilant.
