Cellebrite Advanced JTAG Extraction (CAJE)


Graphic: CAJE Shield

Level - Expert

Course Length: 4 Days


 During this course, participants will learn about the JTAG process, electrical theory, methodologies, and purpose as well as understand the equipment and accessories necessary for successful JTAG extractions. Instructors will help attendees to not only develop, but also to hone fundamental soldering skills, gain practical knowledge with hands-on practice as well as share best practices and legal considerations for processing JTAG extractions. Additionally, participants will learn how to fully leverage the Physical Analyzer to decode JTAG extractions properly. As part of their attendance, participants will receive a Z3X Pro (Easy JTAG) box, a class-specific toolkit, and a Cellebrite soldering practice board.
