Echo
Echo is an experimental generic, static analysis, symbolic execution and emulation framework, that aims to help out with binary code analysis for a variety of platforms.
Echo is released under the LGPLv3 license.
Main Features
- Control flow analysis
- Create static and symbolic flow graphs
- Dominator analysis
- Serialize into scoped flow blocks or a list of instructions
- Data flow analysis
- Create data flow graphs
- Inspect stack and variable dependencies of instructions.
- AST building
- Lift control flow graphs to Abstract Syntax Trees (ASTs).
- Unified generic API.
- Serialize any kind of graph to the dot file format.
- Adding a new platform for flow analysis requires minimal effort
Supported platforms:
| Architecture | Back-end | Control Flow | Data Flow | AST | Purity Classification | Emulation |
|---|---|---|---|---|---|---|
| CIL | AsmResolver | ✓ | ✓ | ✓ | ✓ | ✓ (WIP) |
| CIL | dnlib | ✓ | ✓ | ✓ | ✓ | |
| x86 (32-bit) | Iced | ✓ | ✓ | ✓ | ||
| x86 (64-bit) | Iced | ✓ | ✓ | ✓ |
Compiling
Echo can be built using dotnet build, or any IDE that is capable of building .NET Standard 2.0 projects (such as Visual Studio or JetBrains Rider).
Not all projects need to be built for a working binary to be produced. Only the core libraries found in src/Core are required to be built. Any other project, such as the platform-specific back-ends in the src/Platforms directory and the test projects in test/, is optional and can be unloaded safely.
