A new online tool named 'InAppBrowser' lets you analyze the behavior of in-app browsers embedded within mobile apps and determine if they inject privacy-threatening JavaScript into websites you visit.

The tool was created by developer Felix Krause who warned of this potentially risky behavior earlier in the month, explaining how easy it would be for in-app browsers to track anything the users see and do online by injecting JavaScript trackers on every web page they visit.

The potential of these injections includes accessing browsing history, logging behavior characteristics to derive interests, log taps and key presses, monitoring screenshot actions, and even capturing passwords you enter into login forms.-
