analyzing-golang-malware-with-ghidra

analyzing-golang-malware-with-ghidra is a skill for Claude Code from Mikaru0Mystic/sectinel. It costs 40 tokens per session (2,795 once invoked), scanned A, a copy of analyzing-golang-malware-with-ghidra, Apache-2.0.

A procedure for examining malware written in Go, a programming language, with Ghidra, a tool for analyzing compiled programs. It covers recovering functions, extracting text, and rebuilding type information from stripped binaries.

In plain words
What is it for?
Use it during security investigations, to create detection rules, investigate threats, or check monitoring coverage for Go-based attacks.
Why use it?
Go malware often hides useful names and structures, making ordinary reverse engineering harder.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analyzing-golang-malware-with-ghidra scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Analyzing Golang Malware with Ghidra

Overview

Go (Golang) has become a popular language for malware authors due to its cross-compilation capabilities, static linking that produces self-contained binaries, and the complexity it introduces for reverse engineering. Go binaries contain the entire runtime, standard library, and all dependencies statically linked, resulting in large binaries (often 5-15MB) with thousands of functions. Ghidra struggles with Go-specific string formats (non-null-terminated), stripped function names, and goroutine concurrency patterns. Specialized tools like GoResolver (Volexity, 2025) use control-flow graph similarity to automatically deobfuscate and recover function names in stripped or obfuscated Go binaries.

When to Use

  • When investigating security incidents that require analyzing golang malware with ghidra
  • When building detection rules or threat hunting queries for this domain
  • When SOC analysts need structured procedures for this analysis type
  • When validating security monitoring coverage for related attack techniques

Prerequisites

  • Ghidra 11.0+ with JDK 17+
  • GoResolver plugin (for function name recovery)
  • Go Reverse Engineering Tool Kit (go-re.tk)
  • Python 3.9+ for helper scripts
  • Understanding of Go runtime internals (goroutines, channels, interfaces)
  • Familiarity with Go binary structure (pclntab, moduledata, itab)

Key Concepts

Go Binary Structure

Go binaries embed rich metadata in the pclntab (PC Line Table) structure, which maps program counters to function names, source files, and line numbers. Even stripped binaries retain this metadata. The moduledata structure contains pointers to type information, itabs (interface tables), and the pclntab itself. Go strings are stored as a pointer-length pair rather than null-terminated C strings.

Function Recovery in Stripped Binaries

Despite stripping symbol tables, Go binaries retain function names within the pclntab. However, obfuscation tools like garble rename functions to random strings. GoResolver addresses this by computing control-flow graph signatures of obfuscated functions and matching them against a database of known Go standard library and third-party package functions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
