reverser-overview

To analyze a suspicious binary executable, you can perform triage to identify its format, extract strings, unpack packers, and analyze symbols. Running the 'bin_identify' command provides a quick overview to start understanding its functionality step by step.

Extracting and analyzing IoT firmware is best handled using binwalk to unpack the filesystem and reveal embedded components. This firmware extraction process allows you to inspect router and IoT device binaries for vulnerabilities and functionality.

Unpacking a packed binary requires identifying the packer during initial triage and then applying unpacking techniques to reveal its original form. This allows further static analysis like string extraction and symbol risk analysis on the raw executable.

Developing ROP chains requires tools like Ghidra and r2 to find usable gadgets within the binary. These tools facilitate binary reversing by identifying memory addresses and instruction sequences needed for exploit development.

Binary triage reveals the executable's format, architecture, and security mitigations. Identifying these mitigations during reverse engineering helps you understand the binary's attack surface and guides the approach for ROP chain development.
