zeishr/README.md

I work on tooling for computer security, OS internals, binary analysis, instrumentation, reverse engineering, game security research, and fuzzing.

Technical focus

  • Systems security: hypervisors, virtual machine introspection, debuggers
  • Binary analysis and instrumentation: runtime inspection and internals, process injection
  • Research operations: curated knowledge bases, reproducible environments, automation
  • Vulnerability research tooling: fuzzing techniques (snapshot-based, stateful, structure-aware)

Public work

Selected public repositories and substantial forks grouped by area. Archived projects are kept visible as research notes or historical experiments rather than active maintenance targets.

Systems security, virtualization, and memory

Project Description Stack
xenith Research-focused hypervisor for Xen-based debugging, virtual machine introspection, and automation. archived Rust
awesome-anti-virtualization Curated reference list for anti-virtualization and VM-detection techniques. Research list
libMMU Rust crate for rebuilding virtual address spaces from memory dumps, inspired by the OS-agnostic MMU reconstruction techniques explored in mmushell. archived Rust / Nix
mmushell Substantial fork of EURECOM's memory-forensics PoC; added module packaging, a Nix development shell, MkDocs documentation, and architecture/exporter cleanup. archived Python
secmalloc Secure allocator experiment around malloc/realloc/free-style semantics. archived C

Fuzzing

Project Description Stack
snapchange Fork of awslabs' KVM snapshot fuzzer with dependency updates, container and template fixes, LD_PRELOAD support, fuzzer virtual-memory mapping, clearer VM-exit diagnostics, and snapshell tooling. archived Rust / Python / KVM

Runtime instrumentation and game security

Project Description Stack
mono-injector Rust CLI and GUI for injecting managed assemblies into Unity and other Mono-hosted Windows processes. Rust
mono-rt Dynamic Rust bindings to the Mono runtime for injected tooling and runtime inspection. Rust
strafthack Managed Unity mod for STRAFTAT private-session testing and controlled client-side experimentation. C#
Pity Legacy Garry's Mod scripting project kept as an archive. archived Lua
