INFILTRATE is a deep technical conference that focuses entirely on offensive security issues. Groundbreaking researchers focused on the latest technical issues will demonstrate techniques that you cannot find elsewhere. INFILTRATE is the single-most important event for those who are focused on the technical aspects of offensive security issues, for example, computer and network exploitation, vulnerability discovery, and rootkit and trojan covert protocols. INFILTRATE eschews policy and high-level presentations in favor of just hard-core thought-provoking technical meat.
Talk presented by MWR
- Time: 10:30:00
- Topic: Logic Bug Hunting in Chrome on Android
- Speakers: Georgi Geshev & Rob Miller
- Description: Memory corruption exploits are requiring greater and greater investment in time and effort to bypass the latest mitigations in applications like Chrome and the underlying operating system. When combined with the competition of everyone in the world running a fuzzer, it becomes hard to find and keep unique bugs.
Instead we want to talk about logic flaws - bugs or simply "features" - that enable the attacker to achieve the same goals without fighting the latest and greatest exploit mitigations. We will show the methodology we use for reviewing products and identifying flaws as well as the process of exploiting them. This involves, among other things, developing better understanding and gaining deeper knowledge of a target and identifying security boundaries that usually give rise to assumptions about security checks performed on both sides.
In our example we will show how a logic bug in Chrome for Android allows an attacker to completely bypass Android Nougat security to access the user's files, emails and even install applications without the need for a single memory corruption bug.
