        Contrary to the common code between the two files which is not obfuscated, the additional package called metadata is heavily obfuscatedpic.twitter.com/yjawfCHCtO

        This Fraud Tools is part of the Braintree SDK which is open source on Github: https://github.com/braintree/braintree_android … I was not able to find the source code of this hidden metadata package. Did I miss something or @Paypal is hiding some here?

        You can find the documentation here: https://developers.braintreepayments.com/guides/advanced-fraud-tools/client-side/android/v2 … The customer's device collected data by this lib is not described at all.

        This package is sending a lot of personal informations like: location, locale, ip, device uptime, ssid, total storage space,...pic.twitter.com/smXELIN4M0

        So @Paypal if you don't mind can I ask two questions? Why this "metadata" package is hidden and not open source like the rest of your SDK? Come on! Is personal data means something for you? Why do you need so much infos?

        there is like 0 competent fraud protecting in that sdk btw. We had to implement our own methods of fraud protection, including just not taking credit cards on sprint devices (source of most of our fraud)

        yeah, at this point, ive been patching the SDK in various ways myself for 3yr. I'm actually unaware of anyone else currently using it at any scale due to Playstore rules, its nasty

        Does this mean PayPal is totally insecure? I have a PP account. Luckily, I never used it till now.
