RESim

RESim is a dynamic analysis tool designed for reverse engineering and vulnerability assessment on simulated networked systems, utilizing the Simics platform for high-fidelity emulation of hardware. Its key features include tracing process execution, integrated debugging with IDA Pro and Ghidra, reverse execution, and a custom AFL fuzzer for direct memory injection, all while offering external observation without altering the state of the simulated environment. This tool is particularly effective for analyzing processes and data flow in both Linux and Windows systems without requiring kernel-level knowledge.
