Safe Internet Browsing: What Is A Browser Extension?

Summary: This 2-3 minute blog defines browser extensions and discusses how millions of people use malicious browser extensions unwittingly. Contact GEEKAID Computer and Network Support, the IT experts, at https://www.geek-aid.com/ to find out the browser protection options available.

What Is A Browser Extension?

Wikipedia https://en.wikipedia.org/wiki/Browser_extension defines a browser extension as “a small software module for customizing a web browser. Browsers typically allow a variety of extensions, including user interface modifications, cookie management, ad blocking, and the custom scripting and styling of web pages.” Browser extensions were developed to add more functionality to the browsing experience. However, all new IT-related things are followed by cybercriminals ready to exploit new vulnerabilities. Malicious browser extensions are widespread. Many malicious extensions are relatively benign, even unnoticeable. It is estimated that recently 70% of malicious browser extensions are designed to target users with advertisements or spy on user browser activities. Furthermore, the pandemic spawned a dramatic increase in online purchases, which in turn launched an adware competition to get the attention of prospective shoppers. Fortunately, there are methods for ramping up your browser protection.

Browser Protection

Browser Protection is the addition of cyber security to web browsers to help protect networked computer systems from being attacked and having data breached. Before adding extensions, it is critical to know if they are from trusted sources. For example, Chrome Extension Security offers a comprehensive guide to evaluating different types of “permissions” associated with Chrome extensions. Many extensions require permissions to make changes on a device or web page for them to run:

• Site Permissions – Site permissions require the extension to be explicit about which websites it is permitted to view or modify if granted permission.
• Device Permissions – An extension might also ask for permissions to access what it needs on a device, such as access to storage, a USB port, etc.

Recently, the three biggest browser extension threats have been:

• WebSearch – WebSearch captures users' browsing activities to create a profile for the online offerings they frequent. It then promotes links to its marketing partners to make money from the malicious browser extensions.
  • WebSearch also changes the browser's home page to direct users to affiliated links, thus generating more clicks and revenue.
• AddScript – AddScript runs in the background. Users are lured into using the extensions to gain additional functionality, while the extensions that carry them offer the function of downloading videos from the web.
  • AddScript uses JavaScript to run videos in the background and track YouTube views, generating more revenue.
  • Also, AddScript adds marketing affiliate cookies to the host, creating another revenue stream for the cybercriminal.

Unfortunately for users, a boon for hackers is that most users do not think about or understand the risks involved when using browser extensions. To be sure that your browser, network and all your devices have sufficient security, it is wise to consult IT experts
