Vulnerability Discovery and Triage Automation Training

Register for the March 10-13, 4-day course

Instructor(s):
Richard Johnson

Description:

This class is designed to introduce students to the best tools and technology available for automating vulnerability discovery and crash triage with a focus on delivering a practical approach to applying this technology in real deployments at any scale.

Through an applied understanding of introductory program analysis and binary translation, techniques for finding various bug classes and methods for improved crash debugging will be discussed. We will analyse the properties of memory corruption from integer overflows, uninitialized variables, use-after-free and look at applying tools such as compiler plugins, binary instrumentation frameworks, memory debuggers, and fuzzers to discovering each one.

Next take a deep dive into fuzzing, covering all aspects of this practical approach to finding bugs. As the most approachable and versatile of the available tools, the student will apply various fuzzing techniques to several real-world pieces of software. Students will learn strategies for analysing attack surface, writing grammars, and generating effective corpus. We will explore in detail the latest innovations such as harnessing code coverage for guided evolutionary fuzzing and symbolic reasoning for concolic fuzzing.

We approach crash analysis through the lens of scriptable debuggers and program analysis. We will once again look at properties of how memory corruption manifests in a crashing condition. We will apply tools like reverse debugging and memory debugging scripts to assist in interactively diagnosing root cause of crashes. Then we will leverage the power of dynamic taint tracking and graph slicing to help isolate the path of user controlled input in the program and identify the exact input bytes influencing a crash. Lastly, we will look at possible ways to aid in determining severity of a vulnerability.

This class will focus on x86/x64 architecture and target Windows and Linux environments, however some discussion regarding applications to ARM and mobile platforms will also be included and all of the concepts if not the direct tools will be useful in other environments.

Key Learning Objectives:

PREREQUISITE WARNING Each class has prerequisites for software loads and a laptop is mandatory. These individual class guides will list material the students are expected have knowledge about coming in and software tools that need to be pre-installed before attending so you get the maximum benefit from the focused intermediate or advanced level course. Please pay particular attention to the prerequisites, as the material listed there will not be reviewed in the courses, and will be necessary to get the maximum benefit out of these educational programs.
