Today, from morning till afternoon along with other computer professionals, we are attending HADFEX which is workshops and conference on hacking and digital forensic. It is conducted by University of Islamic Indonesia in Yogyakarta. Very good activities involve many computer professionals coming from different areas in Indonesia. This is to be a place where we can share one another about anything on forensic and hacking. As requested by the HADFEX committee, in this conference, I deliver topic about Mobile Forensic Investigation. I share about basic principles on mobile forensic, starting from physical and logical acquisition to forensic data mechanism. I hope such conference/workshops could continue regularly. Good job for the committee for their hard effort to succeed it.
