Friday, April 15th, 2016

So you’ve got an iPhone, and it’s locked, and you don’t know the passcode. This situation is so common, and the market has so many solutions and “solutions” that we felt a short walkthrough is necessary.

From the point of view of mobile forensics, there are three distinct generations:

  1. iPhone 4 and older (acquisition is trivial)

However, Apple doesn’t make it easy. Instead of using a single two-factor authentication solution (like Google), the company went for two different processes with similar usability and slightly different names. What are the differences between the two verification processes, and how do they affect mobile forensics? Let’s try to find out.
