      Hi fb1h2s, This is very helpful, but what i was wondering is that while doing all this, would ur bank not know that you are attempting to fingerprint or brute force into an account. Even when you are doing it for your own account. I mean would there be not litigation. Is there a way around this?

      Hi thanks for the concern , in my demonstration all I tried to demonstrate with my bank is that IVR logins are bruteforcable and its the same with every other banks, no specifics here. And no bruteforce attempts were made , only login to a personal test account was done.

      Hey fb1h2s, Enjoyed the presentation. Can you please share some sample codes for interfacing python with android for sending AT commands? I believe pyserial would help but the progress has been slow in that direction. Would really appreciate some pointers :-)
