      1. Hi @UIDAI and @KhoslaLabs 👋! Let me show you why it's not a good idea to keep a "debug feature" in the #Aadhaar #Android app you released

      2. In the #Aadhaar #Android app they defined a flag called isLogger which is set to false by defaultpic.twitter.com/PPo16zVLEI

      3. If the flag isLogger is equal to true, every time the writeLog method is called a log file is created in /sdcard/mAadhaar/pic.twitter.com/CP18EYdDsE

      5. To enable the logging 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 apppic.twitter.com/wV5mcgHF6w

      7. If an attacker repack the app with the logging activated and distribute it, all your #Aadhaar data will be available on the sdcard in clear. After that, it super easy for the attacker to upload this log file to his server.

      8. So @UIDAI and @KhoslaLabs, can you ask to your interns...sorry I meant: can you ask to your developers to remove this "debug feature" of the APK?

          Well yes, interns from so called highly prestigious IIT who have done zero innovations anytime in recent history. These stupid Indian tech companies and start-up only hire from such institutes which is totally illogical. Great programmer is by passion and not by just college.

          And did you get a chance to go through about Virtual ID bro? It seems to be another loophole as many of the folks from neighbouring countries are using Aadhaar. Doesn't this VID entitle them with more flexibility and could actually provide a cover to them?
