As a result of Project Zero's efforts to root out security flaws in Samsung's Galaxy S6 Edge device (and by association, likely the entire Galaxy S6 line), owners are now more secure. The team gave themselves a week to root out vulnerabilities. To keep everyone sharp, the researchers made a contest out of it, pitting the North American and European participants against each other. Their efforts resulted in the discovery of 11 vulnerabilities, the "most interesting" of which was CVE-2015-7888. It's a directory traversal bug that allows a file to be written as a system. Project Zero said it was trivially exploitable, though it's also one of several that Samsung has since fixed.
