The most challenging part of writing "The Secret Life of Circuits" wasn't the writing process. It was crafting over 290 full-color illustrations on my own design.

In a few hours, @TeamT5_Official is going to present their research on breaking Samsung S-Boot at #BHUSA. They wrote a technical post about one bug back in June.

Success! The @fluoroacetate duo got the #Samsung Galaxy S10 to connect to their rogue base station and then pushed a file to the phone. Third year in a row. Off to the disclosure room to get all the details.
