ScyllaHide is an advanced open-source x64/x86 usermode Anti-Anti-Debug library. It hooks various functions in usermode to hide debugging. This tool is intended to stay in usermode (ring3). If you need kernelmode (ring0) Anti-Anti-Debug please see TitanHide

ScyllaHide supports various debuggers with plugins:

- OllyDbg v1 and v2
- x64dbg or
- Hex-Rays IDA v6+
- TitanEngine v2 and

PE x64 debugging is fully supported with plugins for x64_dbg and IDA.
