Vexis is a custom x86-64 binary analysis and reverse-engineering platform I built from the ground up in Rust, with a .NET desktop frontend for interactive analysis.
Instead of wrapping an existing disassembly library, I implemented the core instruction-decoding pipeline myself, including legacy and REX prefixes, ModR/M, SIB addressing, RIP-relative addressing, instruction boundaries, and control-flow instructions.
From that decoded instruction stream, Vexis reconstructs basic blocks, functions, and typed control-flow graphs, calculates cyclomatic complexity, identifies anti-disassembly patterns, and generates structured analysis reports.
The visual frontend turns the analysis engine into a usable product: users can inspect full disassembly, explore function-level CFGs, review complexity and control-flow statistics, and analyze entire batches of binaries from one interface.
Key engineering work included:
Custom x86-64 instruction decoder written in Rust
Linear-sweep and recursive-descent analysis strategies
Basic-block and function recovery
Control-flow graph generation and visualization
Cyclomatic complexity and binary statistics
Anti-disassembly detection
Batch analysis across multiple binaries
JSON, Markdown, and Graphviz reporting
Differential testing and fuzz testing of the decoder
.NET GUI communicating with the Rust engine across a clean process boundary
The result is more than a frontend demo: it is a complete analysis pipeline that goes from raw PE64 machine code to searchable disassembly, recovered program structure, visual control flow, and automated reports.
