Why it matters
Recover function names, boundaries, and runtime metadata from stripped Go and Rust binaries where symbols have been removed, enabling security analysis of malware, proprietary tools, and obfuscated executables.
Outcomes
What it gets done
Extract Go pclntab metadata and recover function names using GoReSym or redress
Identify Rust panic strings, crate paths, and unwind symbols to map code structure
Locate language-specific runtime patterns like Go interfaces, slices, and Rust async state machines
Set dynamic breakpoints using Frida guided by configuration strings and logging paths

Overview
Go / Rust Binary Reverse Engineering
This skill reverse-engineers stripped Go and Rust binaries by recovering function names and boundaries from language-specific runtime metadata rather than generic decompilation alone, using GoReSym, redress, the IDA Go plugin, Ghidra, and radare2. Use it when analyzing a stripped Go or Rust binary with no debug symbols, such as Go malware or a Rust release build, where generic IDA or Ghidra decompilation alone falls short.
What it does
This skill reverse-engineers stripped Go and Rust binaries by recovering function boundaries and names from language-specific runtime metadata rather than relying on generic decompilation alone. For Go, it works from go.buildid, leftover runtime symbols, and the pclntab table, using GoReSym, redress, or the IDA Go plugin to recover function names, while paying attention to how interface, slice, and string structures show up in the decompiled output. For Rust, it starts from panic strings, the rust_begin_unwind symbol, and crate-path hints, since generic instantiation tends to bloat the compiled code - the recommended approach is to locate string cross-references first rather than reading the decompiled control flow cold. Async and tokio-based state machines specifically need to be worked out through cross-reference correlation rather than direct reading.
When to use - and when NOT to
Use it on a stripped Go binary (including Go malware) or a Rust release binary where the standard symbol table is gone. It exists to complement general-purpose reversing skills, not replace them: for architecture-agnostic decompilation or CLI-only triage, the general ida-reverse, ghidra-reverse, or radare2 skills are the better starting point, with this skill layered on top once the binary is confirmed to be Go or Rust.
Inputs and outputs
Input is a stripped Go or Rust binary. Output is recovered function names and boundaries, plus an understanding of how the language's own structures (interfaces, slices, strings, panic paths) appear in the decompilation - the basis for further static or dynamic analysis.
Integrations
GoReSym recovers Go metadata; IDA or Ghidra with Go/Rust plugins handle decompilation; radare2 and strings/rabin2 support fast string-based triage. For dynamic work, Frida remains usable, with attention to how Go's own stack and scheduler differ from a typical native binary; log and configuration strings are the recommended first breakpoints.
Who it's for
Malware analysts and reverse engineers who need Go- or Rust-aware recovery techniques on compiled binaries where symbols are stripped, rather than reading raw decompiler output against a moving target.
