Introduction
In this paper I’ll show you how to find an Android’s user pattern lock. I assume that the technique that I’ll demonstrate can work only on a rooted device. Actually, this article will be based on a problem given on a web-based CTF (Capture the Flag, a computer security competition).
Problem statement:
Having doubts about the loyalty of your wife, you’ve decided to read SMS, mail, etc., in her smartphone. Unfortunately it is locked by schema. In spite of this, you still manage to retrieve system files.
You need to find this test scheme to unlock smartphone.
You can find a link to download the full dump of system files on references sections.
