No Source, No Problem! High Speed Binary Fuzzing

Explore high-speed binary fuzzing techniques for finding bugs in complex code bases without source code access in this 59-minute conference talk. Learn about Retrowrite, a binary rewriting framework enabling direct static instrumentation for user-mode binaries and Linux kernel modules. Discover how static binary rewriting achieves low-overhead instrumentation comparable to compile-time methods. Examine techniques like reassembleable assembly, symbolization, and RIP-relative addressing. Understand the implementation of binary versions of Address Sanitizer (ASan) and AFL coverage tracking. Investigate kRetrowrite for instrumenting binary kernel modules with kCov-based coverage tracking and KASan. Gain insights into effective fuzzing, coverage-guided techniques, and crash handling. Compare different approaches to binary instrumentation and explore real-world applications in both userspace and kernel environments.
