One of the more interesting things to emerge from the digital revolution is hacking competitions and prizes, wherein benevolent "white hat" hackers are invited to try and defeat hardware and software in a closed environment. The latest mobile-only edition of the Pwn2Own competition was sponsored by software security company Trend Micro, offering cash prizes to anyone who could get user info, install rogue apps, or completely unlock some of the biggest mainstream phones out there: the Nexus 6P, the Galaxy S6, and the iPhone 6s.
