Sogen Windows user-space emulator bindings

Sogen is a high-performance Windows user space emulator that operates at syscall level, providing full control over process execution through comprehensive hooking capabilities.

Perfect for security research, malware analysis, and DRM research where fine-grained control over process execution is required.

Built in C++ and powered by the backend of your choice:

• Unicorn Engine
• icicle-emu
• Hyper-V (WHP)

Caution is advised when analyzing malware in Sogen, as host isolation might not be perfect.
To mitigate potential risk, use the web version to benefit from the additional safety provided by your browser's sandbox.

• 📝 Advanced Memory Management
  • Supports Windows-specific memory types including reserved, committed, built on top of Unicorn's memory management
• 📦 Complete PE Loading
  • Handles executable and DLL loading with proper memory mapping, relocations, and TLS
• ⚡ Exception Handling
  • Implements Windows structured exception handling (SEH) with proper exception dispatcher and unwinding support
