CVE-2015-7888 Hack The Galaxy: Hunting Bugs in the Samsung Galaxy S6 Edge - Project Zero
Posted by Natalie Silvanovich, Planner of Bug Bashes
Recently, Project Zero researched a popular Android phone, the Samsung Galaxy S6 Edge. We discovered and reported 11 high-impact security issues as a result. This post discusses our motivations behind the research, our approach in looking for vulnerabilities on the device and what we learned by investigating it.
The majority of Android devices are not made by Google, but by external companies known as Original Equipment Manufacturers or OEMs which use the Android Open-Source Project (AOSP) as the basis for mobile devices which they manufacture. OEMs are an important area for Android security research, as they introduce additional (and possibly vulnerable) code into Android devices at all privilege levels, and they decide the frequenc
