Beware: Malware Lurking in Chrome Extensions!
Google Chrome is a popular choice for businesses due to its extensive range of extensions that enhance productivity and browsing experience. From blocking ads to managing tasks, Chrome extensions are essential tools. However, their widespread use also presents significant risks.
The Hidden Dangers of Extensions
Chrome extensions can be incredibly beneficial, but they also pose potential threats. Just like downloading apps on your phone, adding extensions to your browser requires caution. The primary concern is malware, short for malicious software, which is designed to damage systems, steal data, and hijack accounts.
With Chrome holding about 65% of the global browser market share, it’s a prime target for cybercriminals. These attackers often exploit browser vulnerabilities, but a simpler method involves embedding malware within extensions. Despite Google’s efforts to monitor the Chrome Web Store, malicious extensions still slip through the cracks.
The Alarming Statistics
A recent study revealed that from July 2020 to February 2023, approximately 280 million people installed malware-infected Chrome extensions. Shockingly, these extensions often remain available for extended periods. On average, malicious extensions were accessible for 380 days, and those with vulnerable code for about 1,248 days. One notorious extension was available for an astonishing 8.5 years before being removed.
Real-World Examples of Malicious Extensions
- The Great Suspender: This popular extension, used to suspend unused tabs to save memory, was found to contain malicious code after it changed ownership. The new version tracked user activity and collected sensitive data without user consent.
- Copyfish: Initially a benign extension for extracting text from images, Copyfish was compromised when hackers took control of the developer’s account. The altered extension began injecting ads and tracking user behavior.
- WebEx Extension: Cisco’s WebEx extension, widely used for online meetings, had a critical vulnerability that allowed attackers to execute arbitrary code on users’ systems, putting sensitive business data at risk.
- DataSpii: This incident involved several popular extensions that collected users’ browsing history and transmitted it to a third-party server. Sensitive information, including medical records and financial details, was exposed, affecting millions of users.
- Fakespot: Designed to help users identify fake reviews on e-commerce sites, Fakespot’s extension was removed from the Chrome Web Store after it was found to interfere with user sessions and compromise personal data.
How to Protect Your Business
To safeguard your business from malicious Chrome extensions, follow these five essential steps:
- Check External Reviews: Internal ratings and reviews on the Chrome Web Store can be misleading. Seek external reviews from reputable tech websites to assess the safety of an extension. For example, websites like TechCrunch, PCMag, and Wired often review popular extensions and can provide insights into their safety.
- Monitor Permissions: Be wary if an extension requests more permissions than necessary. Extensive access to your data or system can be a red flag. For instance, if a simple ad blocker requests access to your file system or personal data, it might be malicious.
- Use Security Software: Employ robust security software to detect and block malware before it causes harm. This serves as a critical defense line if a malicious extension is inadvertently installed. Products like Norton, McAfee, and Bitdefender offer comprehensive protection against such threats.
- Evaluate Necessity: Consider whether you truly need a new extension. Sometimes, visiting a website can provide the same functionality without the risk. For instance, instead of using an extension to check your email, simply visit your email provider’s website.
- Stick to Trusted Sources: Only install extensions from well-known and trusted sources. This significantly reduces the risk of encountering harmful extensions. Extensions from companies like Google, Microsoft, and other reputable developers are generally safer bets.
