You’re putting your privacy at risk when you click on links in Instagram, TikTok, and other apps.

In-app browsers can be a joke in comparison to fully-featured browsing apps, however they also pose a serious security and privacy hazard. A lot of apps place data trackers into websites that which you access through their in-app browser by using an approach known as Javascript injection. It is a method of adding an extra code to the page while it loads. These trackers could collect the history of your browsing, log-in information and even keyboard clicks and even text entry.

Although it isn’t always employed for malicious purposes it can pose a security threat that, until recently it was difficult to verify for in-app browsers. Fortunately Security researcher Flix Krause’s latest ap(p)tly called program, InAppBrowser, determines if an app’s built-in browser makes use of potentially dangerous Javascript injections to monitor your personal data.

While InAppBrowser only works with applications with an integrated web browser for example, TikTok, Instagram, or Messenger You can also utilize it on your desktop to search for Javascript injections in browser extensions.

If you’re concerned about the app (or browser plugin), try InAppBrowser test to see whether it’s doing something suspicious. Here’s how:

On mobile devices [iOS/Android]: Open the app you’d like to test to test and then open inappbrowser.com in the web browser built into the app. A simple method to accomplish this is to share the URL to yourself via a message or comment, or even a post. Alternatively, open a link to a website in the app (any web link works), then go to https://inappbrowser.com.
On desktops: To test websites and browser extensions on your desktop start your browser of choice and then go to inappbrowser.com.
After the site is loaded it will display an explanation of any suspicious Javascript behaviour that InApBrowser detects (if there is any) as well as explanations of what the code could be employed to accomplish.

These readings will help you identify fraudulent behavior, however there are a few cautions to consider.

The most important thing is that InAppBrowser just alerts users to the presence of Javascript injection, but it doesn’t know the difference between an app and a browser extension is dangerous. It also flags applications as well as browser extension extensions which employ Javascript injection, but do nottrack you in any way. This means that private browsing extensions that block websites’ trackers, apps that collect browsing information for marketing or troubleshooting purposes (like TikTok), and malicious apps that actually monitor your activities will be able to trigger similar warnings. In fact, Krause cautions against making assumptions when an application uses Javascript injection.

In the same way, InAppBrowser can’t alert you to different types of tracking applications or browsers. It’s also not able to tell you about other websites and apps that could employ. This means that an app could fail the tests of InAppBrowser but collect your information through different methods and therefore, don’t count on InAppBrowser as the only method to test the app’s security. Still, it’s important to know if an app uses Javascript injections–maliciously or otherwise–so you can decide for yourself if the app is worth using.

If you discover that the app is monitoring you and you wish to get rid of it, there are two choices. The best option is to uninstall the application. If it’s not in you phone, it won’t be able to follow you.

If you’d like to keep an application around but stop the tracking of your device, check the settings of the app and check what you can do to change your default web browser into one that you prefer such as Safari, Firefox, or even Chrome. Safari is a great choice since the latest versions stop a number of Javascript actions that InAppBrowser advises against.

Furthermore, disable app tracking by going to your iOS as well as Android setting menus. This is more beneficial to iOS users, however it is a good way to block ads on Android too. Stop tracking location Also. We recommend altering these settings regardless no matter if the application you’re using has passed the Javascript examination test.
