As part of my freelance security research I have resolved some CVEs and intering bugs in bug bounty programs.
I helped the carabinieri of the R.O.S. (Special Operational Grouping) in the activity of bypass / PIN unlocking of Apple phones with IOS system and recommended the method of tracking cell phones in a certain area for a double homicide case. All the activities were carried out with positive results.
Other PIN unlocking activities for the local police in my city.
