In this post guys from Senrio try to explain you what JTAG is. Probably you, as digital forensics examiner (or even analyst) already know what is it and even use it in your every day mobile forensic examinations, but if not – it’s you chance!
The authors start from answer to the question – “Why Do Manufacturers Use JTAG?”. After they give you some basics: 5 pins, Test Access Port, etc. Also you learn how to use JTAG for security research, including demonstration of rooting home router.
