Ian Beer is a British computer security expert and white hat hacker, currently residing in Switzerland and working for Google as part of its Project Zero. Beer was the first security expert to publish his findings under the "Project Zero" name in the spring of 2014; at this time, the project was not yet revealed and crediting the newly discovered vulnerabilites to it led to some speculation.
He is known for discovering a large number of security vulnerabilities in Apple products, including iOS,Safari and MacOS, as well as helping create jailbreaks for iOS versions. One such discovery forced Apple to rewrite significant parts of the MacOS and iOS kernel.
