Crate libinject 

Libinject

A static library crate which is linked with inject.dll and winafl.dll. Note that libinject can only be compiled for a Windows target.

Contains:

• Rust bindings for the DynamoRIO C library (auto-generated from the C bindings using rust-bindgen).
• A CLI interface for initiating DynamoRIO runs along a given trajectory of the Network Event Tree (NET).
• Instrumentation to interpose on network API calls, using the parsed trajectory to decide how to respond to each network event (e.g. whether to accept or reject a connect call, and what responses to provide to a given request).
• Instrumentation to collect additional, fine-grained coverage information when fuzzing.

Modules

cli

cmp

Instrumentation for collecting fine-grained coverage information: including both i) wrapping external symbols in the loaded-module space; and ii) individually instrumenting all CPU-level CMP and TEST instructions found in the target module.

connections

drcore

drwrap

ffi

fuzzer

instrument

Shadow-stack instrumentation: Exports the instruction_event symbol, which can be registered with DynamoRIO to instrument basic blocks such that a shadow callstack is maintained while to binary executes. At any point in execution this shadow-stack can be queried for the raw absolute frame addresses of the function in the current callstack.

module_load_event

Called by DynamoRio when each C module is loaded. Each .dll will be a module, and the main binary itself will be comprised of one or more modules.
