The past few years have seen a leap in fuzzing technology. The original
paradigm established a decade ago resulted in two widely deployed
approaches to fuzzing: sample based mutation and model based generation.
Thanks to ever-increasing computational performance and better
engineering, newer guided fuzzing approaches have proven to be supremely
effective with a low cost of deployment. This talk will explore a few
different approaches to guided fuzzing through dynamic analysis
including code coverage analysis, constraint solving, and
sampling/profiling based feedback mechanisms.
Novel contributions in this talk include:
- Opensource Windows Driver enabling Intel “Processor Trace”
- DBI based tracing engine for Windows/Linux/OSX binaries
- American Fuzzy Lop with full support for Windows binary targets
