If you use Google Chrome in your business, you’re likely familiar with the many extensions available. These handy tools can enhance your browsing experience by blocking ads, reducing distractions, and adding numerous features.
While extensions can significantly improve browser functionality, they can also pose a significant security risk. Just as you need to be cautious when installing new apps on your smartphone, you should exercise the same level of care when adding new extensions to your browser, as they may come with hidden dangers, including malware.
Malware, short for malicious software, is any software intentionally designed to cause damage to a computer, server, or network. Cybercriminals use malware for various nefarious purposes, such as stealing data, hijacking systems, and even emptying bank accounts. Given the vast amount of sensitive information accessible through browsers, cybercriminals are always on the lookout for ways to exploit vulnerabilities in popular platforms like Google Chrome.
Google Chrome dominates the global browser market with around 65% market share, making it the most popular browser worldwide. This popularity inevitably makes Chrome a prime target for cybercriminals looking to exploit its vast user base. While some attacks directly target vulnerabilities within the browser itself, a more accessible avenue for these criminals is through malicious extensions that contain malware.
Despite Google’s rigorous oversight of its Chrome Web Store, risks still exist. A recent report highlighted that between July 2020 and February 2023, around 280 million people downloaded malware-infected Chrome extensions. This staggering number underscores the importance of being vigilant.
Alarmingly, many malicious extensions remained available on the Chrome Web Store for extended periods of time. On average, extensions filled with malware stayed online for about 380 days, while those with vulnerable code were available for approximately 1,248 days. One particularly notorious extension managed to remain downloadable for an astonishing eight and a half years before it was finally removed.
So, how can you safeguard your business from the threat of malicious extensions? Here are five steps to help protect your systems:
- Check External Reviews: While ratings and reviews on the Chrome Web Store can offer some insight, they are not always reliable. Many malicious extensions lack reviews entirely. Instead, seek external reviews from reputable tech websites to determine whether an extension is safe.
- Scrutinize Permissions: Pay attention to the permissions an extension requests. If a new extension asks for more access than seems necessary, this could be a red flag. Be especially wary of requests for extensive access to your data or system.
- Use Security Software: Employ robust security software to detect and block malware before it can cause harm. This software acts as your last line of defense if you accidentally install a malicious extension.
- Assess Necessity: Before installing any new software or browser extensions, consider whether you genuinely need it. Often, you can achieve the same functionality by visiting a website directly, avoiding the need for an additional extension.
- Stick to Trusted Sources: Only install extensions from trusted sources or well-known software providers. This precaution significantly reduces the risk of downloading a harmful extension.
Given Chrome’s status as the most popular browser, it will always attract the attention of cybercriminals. Although Google’s security team works diligently to review every Chrome extension for safety, users must remain vigilant. Regularly review your installed extensions, remove those you no longer use, and stay informed about potential threats.
