Triton is a dynamic binary analysis library. Build your own program analysis tools, automate your reverse engineering, perform software verification or just emulate code.
Role in this project:Back-end Developer & Systems Engineer
Back-end Developer & Systems EngineerContributions:6 reviews, 239 commits, 57 PRs in 3 years 2 months
Contributions summary:Christian was primarily involved in adding support for the ARM32 architecture to the Triton dynamic binary analysis library, focusing on the core CPU implementation and semantics for various instructions. Their work involved creating the necessary file structure, modifying existing architecture files, and updating Python bindings for the new architecture. Furthermore, the user added support for Thumb instructions and implemented semantics for instructions, as well as involved in test for ARM and Thumb branches.
