spim is a self-contained software simulator for running R2000/R3000 assembly language programs. It reads and can immediately execute files containing assembly language code. spim also provides a debugger and simple set of operating system services. spim provides both a simple, textual interface and a fancier, graphical interface. The package includes complete source code and documentation.
DIOTA is a just-in-time instrumentation tool for Intel binaries. It allows you to create a dynamic loadable library that can be attached to a program running under Linux. DIOTA can instrument all memory operations in the application and the used libraries (e.g., for checking for faulty memory accesses), calls of dynamically linked procedures (malloc, printf, etc.), detect the code executed during a particular run, and more.
joeq is a Java 2 (JDK 1.3 and 1.4) compatible virtual machine. It is unique in that it is entirely implemented in Java, leading to greater reliability, portability, maintainability, and efficiency. It is also language-independent, so code from any supported language can be seamlessly compiled, linked, and executed dynamically.
Fenris is a multipurpose tracer, debugger, and code analysis tool that detects and documents high-level language constructions, can recover symbols, graph program execution flow, detect internal functions, recover symbol tables, and deal with anti-debugging protection. It features a command-line interface as well as a SoftICE-alike GUI and Web frontend.
The Obcode (obfuscated code) library allows the programmer to perform arithmetic (e.g. data encryption and serial code generation) over abstract, parameterizable, and obfuscated data types using special high-level operators. The resulting low-level binary code doesn't reveal any real data directly and is if not very difficult, then at least very boring to reverse engineer and trace.
KMD is a multi-processor debugger. It can debug with hardware boards over serial ports or with software emulators (ARM and MIPS emulators are included in the project). Using the pipe option you can debug over the network or any other communication medium. It can load many executable formats such as ELF, and display and follow the original source even from multiple source file programs. There is support for breakpoints and watchpoints which can trap on specific data (such as loading or executing specific instructions). Support for other features such as FPGA's is also available, allowing loading or any control required to drive a specific hardware device. The project uses chump to allow disassembly and line assembly. Chump also allows new architectures to be easily added without the need to recompile the system. Communication with the backend is done using two pipes/fifos using a simple set of codes. Back end communication program can be created using very little memory on the target device.
Grammar-based software designed to utilize the logic contained within grammar.
