1	# Analyzing Golang Malware Internals
2
3	## When to Use
4
5	- You have a Go-compiled binary (often large, statically linked) and standard symbol recovery
6	fails because user symbols are stripped.
7	- You need function names from the pclntab, the Go version, and embedded package/module paths.
8
9	Do not use this for non-Go binaries — confirm the Go build signature first. This skill reads
10	the binary statically and executes nothing.
11
12	## Prerequisites
13
14	- The Go binary (read inertly).
15
16	## Safety & Handling
17
18	- Read bytes statically; treat strings as untrusted data.
19
20	## Workflow
21
22	### Step 1: Confirm it is Go and get the version
23
24	```bash
25	python scripts/analyst.py info sample.bin
26	```
27
28	Looks for the `Go build ID`, the `go1.x` version string, and `runtime.` references.
29
30	### Step 2: Recover function names from pclntab
31
32	The pclntab (preceded by a magic like `\xfb\xff\xff\xff`/`\xf0\xff\xff\xff` across Go versions)
33	contains function name strings; extract `main.`, package-qualified, and `runtime.` names.
34
35	### Step 3: Enumerate package paths
36
37	List embedded import/module paths (`github.com/...`, vendored deps) to fingerprint capabilities
38	and third-party libraries.
39
40	### Step 4: Map and document
41
42	Map suspicious packages (networking, crypto, exec) to behavior and ATT&CK.
43
44	## Validation
45
46	- The Go build signature/version is confirmed before deeper parsing.
47	- Recovered names include plausible `main.*`/package-qualified functions.
48	- Package paths are real module paths, not random strings.
49
50	## Pitfalls
51
52	- pclntab magic differs across Go versions; try the known set.
53	- Obfuscators (garble) rename symbols and strip build info — names may be hashed.
54	- Confusing vendored library code with the author's `main` package.
55
56	## References
57
58	- See [`references/api-reference.md`](references/api-reference.md) for the analyzer.
59	- Go pclntab/buildinfo references (linked in frontmatter).
