Is That Chrome Extension Filled with Malware?

Are you using Google Chrome in your business? Extensions can be great tools to enhance your browsing experience, from blocking ads to reducing distractions. However, it’s crucial to be cautious when adding new extensions, as they can pose a risk of malware.

Malware, short for malicious software, is deliberately designed to cause severe damage to computers, servers, or networks. Cybercriminals use malware to steal data, hijack systems, and even empty bank accounts.

Google Chrome’s holding of approximately 65% of the browser market makes it a prime target for cybercriminals. While some cyber-attacks exploit browser vulnerabilities, malicious extensions are an easier way to target Chrome users.

The risk remains despite Google’s efforts to monitor the Chrome Web Store. A recent report claims 280 million people installed a malware-infected Chrome extension between July 2020 and February 2023. This staggering number highlights the importance of vigilance.

Many malicious extensions remain available for download for a long time. 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.

To protect yourself and your business from malicious extensions, consider these five steps:

1. External Reviews: Ratings and reviews on the Chrome Web Store can be unreliable. Look for reviews from trusted tech sites to judge whether an extension is safe.
2. Permissions: Be cautious if an extension asks for more permissions than necessary. This could be a red flag if it requests extensive access to your data or system.
3. Security Software: Use robust security software to catch malware before it can do any harm. This is your last line of defense if you accidentally install a malicious extension.
4. Necessity: Before installing new software or browser extensions, consider whether you need it. Often, you can achieve the same functionality by visiting a website.
5. 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 always be a target for cybercriminals. While Google’s security team works hard to review every Chrome extension to ensure safety, it’s crucial to remain vigilant.
