Eric Castro is an iOS Engineer at Data Theorem. His background in Apple's iOS ecosystem dates back from late 2007 with the first jailbreak ever. In early 2008, he released 'iSlsk', a SoulSeek client for jailbroken iPhones becoming the first P2P file sharing app ever on a mobile platform, when the AppStore didn't even exist yet. Since then, he has been deeply involved into the reverse engineering of iOS private frameworks in order to circumvent many of Apple's limitations on their devices. Most notably with his jailbreak app 'MewSeek', with crucial collaboration from security expert Nikias Bassen, it allowed syncing mp3 files to the iPhone's internal music library without the need of iTunes or any computer. Eric joined Data Theorem in 2014 to apply his expertise in iOS internals allowing to further develop its cloud-enabled scanning service for mobile application security and data privacy.
