E9Patch is a static binary rewriting tool for x86_64 Linux ELF executables and shared objects, producing patched binaries that work as drop-in replacements. It includes E9Tool, a linear disassembly frontend for applying instrumentation like instruction tracing.

Use cases

• patch a compiled binary without source code
• instrument instructions in an ELF binary for tracing
• insert AFL fuzzing instrumentation into a stripped binary
• harden or modify a large binary like a web browser
• intercept syscalls by rewriting libc

When to choose

• you need to modify or instrument a Linux x86_64 ELF binary without recompiling
• you need low-overhead, scalable rewriting of very large binaries
• you want a drop-in patched binary with no extra runtime dependencies

When to avoid

• you need dynamic (runtime) instrumentation rather than static rewriting
• your target is not a Linux x86_64 ELF binary
• you need source-level modification and can rebuild from source
