# {\Delta}Breakpad: Diversified Binary Crash Reporting

## TL;DR

{ extDelta}Breakpad enhances crash reporting for diversified software by integrating code diversification techniques with minimal overhead, improving security against code reuse attacks while maintaining accurate crash diagnostics.

## Contribution

It introduces a method to diversify binaries and adapt crash reporting systems with minimal overhead, supporting effective security and debugging.

## Key findings

- Diversification significantly mitigates code reuse attacks.
- Overheads in computation, storage, and communication are minimal.
- The approach maintains accurate crash reporting in diversified binaries.

## Abstract

This paper introduces {\Delta}Breakpad. It extends the Breakpad crash reporting system to handle software diversity effectively and efficiently by replicating and patching the debug information of diversified software versions. Simple adaptations to existing open source compiler tools are presented that on the one hand introduce significant amounts of diversification in the code and stack layout of ARMv7 binaries to mitigate the widespread deployment of code injection and code reuse attacks, while on the other hand still supporting accurate crash reporting. An evaluation on SPEC2006 benchmarks demonstrates that the corresponding computational, storage, and communication overheads are small.
