analyzing-golang-malware-internals

Analyzes Go-compiled malware by recovering function names from the pclntab, detecting the Go build/version string, and listing embedded package paths to overcome stripped symbols. Activates for requests to analyze Go malware, recover Go function names, or identify a Golang binary build.

Analyzing Golang Malware Internals

When to Use

  • You have a Go-compiled binary (often large, statically linked) and standard symbol recovery fails because user symbols are stripped.
  • You need function names from the pclntab, the Go version, and embedded package/module paths.

Do not use this for non-Go binaries — confirm the Go build signature first. This skill reads the binary statically and executes nothing.

Prerequisites

  • The Go binary (read inertly).

Safety & Handling

  • Read bytes statically; treat strings as untrusted data.

Workflow

Step 1: Confirm it is Go and get the version

python scripts/analyst.py info sample.bin

Looks for the Go build ID, the go1.x version string, and runtime. references.

Step 2: Recover function names from pclntab

The pclntab (preceded by a magic like \xfb\xff\xff\xff/\xf0\xff\xff\xff across Go versions) contains function name strings; extract main.*, package-qualified, and runtime.* names.

Step 3: Enumerate package paths

List embedded import/module paths (github.com/..., vendored deps) to fingerprint capabilities and third-party libraries.

Step 4: Map and document

Map suspicious packages (networking, crypto, exec) to behavior and ATT&CK.

Validation

  • The Go build signature/version is confirmed before deeper parsing.
  • Recovered names include plausible main.*/package-qualified functions.
  • Package paths are real module paths, not random strings.

Pitfalls

  • pclntab magic differs across Go versions; try the known set.
  • Obfuscators (garble) rename symbols and strip build info — names may be hashed.
  • Confusing vendored library code with the author's main package.
