      1. Hi @UIDAI and @KhoslaLabs 👋! Let me show you how to bypass the protection mechanism you set up and run the #Aadhaar #Android app on a rooted phone.

      2. When an user start the #Aadhaar #Android app on a rooted phone, he will obtain a toast with the following message: "Your device is rooted. For security purpose you can not use this application"pic.twitter.com/Mb0Qypqqe4

      3. In the splash screen activity you are checking if the device is rooted with 3 different methods.pic.twitter.com/GLIR1hWzML

      4. In the CheckRootUtil class, you implemented 5 different methods to check if the device is rooted but only 3 are used 🤷‍♂️ https://gist.github.com/fs0c131y/b8e3d3f16d2cb9df46707e8fd1f65217 …

      5. I guess the @UIDAI and @KhoslaLabs developers are working with emulators when they developed the app. So they implemented a way to bypass this root check...🤦‍♂️ If the flag isEmulator is set to true, the method will always return false and you bypass the root check 🤦‍♂️pic.twitter.com/D2yivWbgF2

      6. You just have to: - unpack the #Aadhaar #Android app with #apktool - change v1 to v0 in one line - repack the app with apktool - resign the app You can run the app on a rooted phone!pic.twitter.com/Hay77rX3EA

      Ok so the security of an app can be weakened by changing the app.... Isn't that true of anything? If they used a cert check, you could change the program code to bypass that check too. What's your point here?

      As well said by @troyhunt in his blog post, nothing is "Hack proof" but you can protect yourself against basic attack when you handle the data of 1.2 billion of people...

      Someone who recompiles the app so it can run on their rooted device is only hacking themselves. Unless you are talking about someone redistributing such an apk - but that would be the same risk with any app. Would your suggestion be to send the apk sig with API reqs?

      No, you are wrong on this point, you can hack an entire service, access other user data for example, by recompiling an app

          Even if that's true, it's not a problem unique to Aadhaar. Anyone can recompile any app. Anyone can 'hack' a website w liberal use of chromebug. I dont think 'someone could change the code' is a legitimate security flaw (as long as APIs are secure & dont implicitly trust clients)

          Reverse patching an App is a big problem under certain conditions, particularly if the back end trusts *that the app* is not patched. I will say no more except that a reflexive response of "it is not a problem" and "everyone has the same problem" is a hopeless security posture.

          Replying to @iam_anandv @rockgecko_dev and

          To understand why it is a problem, start thinking about, why installing mAadhaar on a rooted phone is a problem and how *many non-tech folks* even can tell the difference between a rooted phone and non-rooted phone. On twitter saying anything more is not an option. #
