Between 2016 and 2018, Ian Beer found more than 30 vulnerabilities in the iPhone’s operating system. These bugs were worth millions of dollars on the open market.

Beer’s ultimate goal is to make the iPhone even more secure, but he doesn't work at Apple. He's a hacker for Google’s Project Zero, an elite hacking team focused on finding bugs in popular software and products made by companies like Apple, Microsoft, and by Google itself.
