We’re pleased to announce that Yong Chuan Koh, who is based in our Singapore office, will be presenting at REcon this year.
REcon is a computer security conference with a focus on reverse engineering and advanced exploitation techniques. It is held annually in Montreal, Canada.
The conference offers a single track of presentations over the span of three days along with technical training sessions held before the presentation dates. Technical training varies in length between two and four days.
Topic: Understanding the Microsoft Office 2013 Protected-View Sandbox
Speaker: Yong Chuan Koh
Sandboxing is a popular modern technique used by vendors to minimize the damages that attackers might inflict on a compromised system by restricting the application’s trust boundaries. Sandboxing raises the bar for exploitation because the compromised application is now “contained”, and typically need at least another vulnerability to escape the sandbox container to achieve the same level of system compromise. As a testament of its effectiveness, popular applications that have adopted sandboxing technique include Chrome, Internet Explorer, Firefox and Adobe Reader.
Microsoft Office is no exception; its sandbox is implemented as the Protected-View feature since Office 2010. At present, there are many excellent sandbox researches for Chrome, Internet Explorer Enhanced Protected Mode and Adobe Reader. However there is no similar research for the Microsoft Office Protected-View sandbox yet.
This talk aims to bridge this gap. The first part of this talk will sketch the Protected-View sandbox internals by discussing about its architecture, its initialization sequence and the system resource restrictions. The second part will discuss the Inter-Process Communication (IPC) mechanism, including the mode of communication, undocumented objects involved, format of IPC messages and the semantics of selected IPC messages.
