If your business uses Google Chrome, you’re likely familiar with extensions, and may have had your fair chasre of Chrome extension issues. When working, these handy add-ons can enhance your browsing experience by blocking unwanted ads, boosting productivity, and reducing distractions. But while Chrome extensions offer convenience, they can also introduce a hidden risk: malware. If you’re having odd behaviour or peformance Chrome extension issues, that might be a clue. But others look like they’re doing their job. Sneaky.
What Is Malware?
Malware (short for malicious software) is intentionally designed to damage or gain unauthorised access to computer systems. Cyber criminals frequently use malware to steal data, hijack systems, or even siphon money from your accounts. With Chrome holding 65% of the global browser market share, it’s an attractive target for these attacks. And one common way they exploit vulnerabilities is through malicious Chrome extensions.
Although Google maintains a tight grip on the Chrome Web Store, some dangerous extensions can still slip through the cracks. A recent report revealed that between July 2020 and February 2023, 280 million users installed malware-infected Chrome extensions. That staggering figure underscores the importance of vigilance when adding new extensions.
In some cases, malicious extensions remain available for a shockingly long time. The report found that on average, infected extensions stayed on the Web Store for 380 days. Extensions with vulnerable code were available for about 1,248 days, with one notorious extension remaining downloadable for an astonishing 8.5 years before it was finally removed.
Get Protected
So, how can you protect yourself from Chrome extension issues? Here are five critical steps your business should follow to stay safe:
- External reviews: Don’t rely solely on the Chrome Web Store reviews. Malicious extensions often have fake reviews. Instead, look for trusted tech sites and security forums for more accurate assessments of an extension’s safety.
- Permissions: Be cautious of any extension that requests unnecessary access to your data or system. If an extension asks for more permissions than it needs, this could signal a potential threat.
- Security software: Ensure that you have robust security software installed that can detect and block malware before it does any harm. This acts as a final line of defence in case you install a dangerous extension.
- Necessity: Ask yourself if you really need the extension. Often, the functionality can be achieved by visiting a secure website rather than installing additional software.
- Trusted sources: Stick to extensions from trusted sources or well-known providers. Avoid obscure or unknown developers to minimise your risk.
Even though Google works hard to secure Chrome, the browser’s popularity makes it a prime target for cyber criminals. The best defence is a proactive approach that includes regularly reviewing your extensions and using security measures that can catch malware before it causes damage.
