Maybe it's a vendor-supplied library without source +code, a suspicious download, an embedded firmware image, or a legacy executable +your team inherited. You want to answer questions like: What APIs does it call? +Are there any suspicious capabilities? What does this specific function do? + +This skill teaches AI agents how to use the `binary` CLI — a non-interactive, +flag-driven analysis harness — to answer those questions systematically. The +agent learns when to run a fast triage versus a deep function-level dive, how to +separate deterministic evidence from interpretation, and how to produce +structured, auditable reports. + +After installing this skill, your agent can: +- **Triage unknown binaries** — identify suspicious API imports, assess + capabilities, and produce evidence-backed reports in under a minute. +- **Decompile and disassemble** specific functions to understand logic without + source code. +- **Map call graphs and cross-references** to trace how functions relate to each + other. +- **Extract structural data** — sections, entry points, imports, exports, + symbols, and strings — with cursor-based pagination. +- **Generate auditable reports** in Markdown, JSON, HTML, or PDF with full + provenance (binary SHA-256, adapter version, analysis profile). + +## What You Get + +| Directory | What It Provides | +|-----------|-----------------| +| `SKILL.md` | Agent instructions: trigger rules, workflow phases, safety boundaries, evidence standards, and reference routing. | +| `README.md` | This file — human-facing documentation. | +| `scripts/binary` | The CLI entrypoint — 37 commands across 14 functional groups.

This skill is static-analysis only (V1). +- **Binary patching or modification** — hex-editing, resource editing, + repackaging. The analysis harness is read-only by design. +- **Binaries you already fully understand** — if the user is asking for + documentation or explanation of known code, use a general-purpose skill. +- **Source-code analysis** — C, C++, Rust, or assembly source files. Use a + language-specific or general code-analysis skill instead. +- **Network forensics or packet capture** — PCAP analysis, protocol reverse + engineering at the wire level. Use a network-focused skill. +- **Live memory forensics** — process memory dumps, heap analysis. Static + analysis of memory-mapped regions from files is in scope; live-process + introspection is not. + +## What the Agent Owns vs What the CLI Owns + +This boundary is the most important concept in the skill. Crossing it produces +unreliable evidence, wasted context, or both. + +| Layer | Responsibility | Must NOT | +|-------|---------------|----------| +| **Agent (you)** | Form hypotheses about binary behavior. Choose which analyses to run and in what order. Synthesize CLI evidence into conclusions. Explain findings to the user in plain language. Write evidence-backed reports. | Invent facts not present in CLI output. Claim certainty where the CLI reports partial results or low confidence. Skip diagnostic warnings. | +| **CLI** | Parse arguments, manage project lifecycle, run Ghidra analysis, serialize canonical entities, emit JSON envelopes, enforce safety limits. | Interpret results, draw conclusions, or produce narrative prose. | + +**Rule of thumb:** If a fact appears in a CLI JSON response under `data`, it is +deterministic evidence you can cite. If you are tempted to infer something not +directly supported by that evidence, flag it as an agent inference and note the +confidence gap. + +## Core Workflow + +Every analysis session follows this sequence. Do not skip phases — each one +produces evidence the next phase depends on. + +### Phase 1: Environment Check + +```bash +binary doctor --json +``` + +If any component reports `severity: "ERROR"`, run the bootstrap plan: + +```bash +binary bootstrap --plan --json +``` + +Review the plan. If the user authorizes installation, run: + +```bash +binary bootstrap --apply --json +``` + +Verify with `binary version --json`. + +### Phase 2: Project Setup + +Create a project for every binary you analyze. Projects isolate analysis state +and provide an audit trail. + +```bash +binary project create --json +binary import --project --json +``` + +Use copy mode (default) for reproducibility. Use `--reference` only when the +binary is large, read-only, or shared across projects, and explain the +staleness risk to the user. + +### Phase 3: Initial Analysis + +Run the standard analysis profile first. It covers the structural queries most +triage workflows need. + +```bash +binary analyze --project --json +``` + +Check the response: +- `success: true, partial: false` — proceed to Phase 4. +- `success: true, partial: true` — review `diagnostics` for gaps. Proceed with + bounded results, noting limitations. +- `success: false, partial: true` — timeout. Extract what completed, report + what did not. +- `success: false, partial: false` — hard failure. Check `diagnostics` for the + failure reason. The project is now FAILED; run `binary project clean` to + reset. + +### Phase 4: Evidence Collection + +Choose analyses based on the user's question. Run these in order, building +evidence from broad to specific. + +**For triage (broad survey):** +```bash +binary triage --project --json +binary suspicious-apis --project --json +binary capability-map --project --json +``` + +**For structural understanding:** +```bash +binary metadata --project --json +binary sections --project --json +binary entrypoints --project --json +binary imports --project --json +binary exports --project --json +binary strings --project --contains "" --json +``` + +**For function-level deep-dive:** +```bash +binary functions --project --json +binary decompile --project --json +binary disassemble --project --json +binary xrefs --project --json +binary callers --project --json +binary callees --project --json +binary callgraph --project --depth 3 --json +``` + +**For path analysis:** +```bash +binary trace --project --from --to --json +``` + +### Phase 5: Report and Handoff + +Generate a durable report before explaining results to the user: + +```bash +binary export-report --project --type triage --format markdown --json +``` + +Read the report. Synthesize findings into a clear explanation. Always mark +agent inferences separately from CLI evidence. Example: + +``` +## CLI Evidence (deterministic) +- The binary imports VirtualAlloc, WriteProcessMemory, and CreateRemoteThread + (suspicious-apis, risk_score 8, rule_id: process-injection) +- Entry point at 0x401000, 3 sections (.text, .rdata, .data) + +## Agent Assessment (inference) +- The API combination suggests process injection capability. This is a + heuristic, not a confirmed behavior. The binary would need to be executed + (out of scope for static analysis) to confirm. +``` + +## Safety Boundaries + +The CLI enforces these boundaries automatically. You must never attempt to +bypass them, even if a user asks. + +| Boundary | Enforcement | Why | +|----------|-------------|-----| +| **Never execute the target** | CLI refuses; no execution path exists | Static analysis only | +| **Never load target as a library** | Not implemented; no dlopen/LoadLibrary path | Prevents unintended code execution | +| **Never expose a network listener** | No HTTP, MCP, or socket servers | The CLI is a local tool | +| **Never upload hashes or samples** | No telemetry, no outbound calls | Privacy and security | +| **Path containment** | All project paths validated for traversal | Prevents workspace escape | +| **Output size limits** | Default 64 MB, max 256 MB JSON | Prevents context exhaustion | +| **Memory limits** | Configurable per-operation ceiling | Prevents OOM during large analyses | +| **Timeout enforcement** | Default 300s, configurable per-command | Bounded operations | +| **Result count limits** | Paginated with default 100, max 1000 | Prevents unbounded output | +| **Graph depth limits** | Callgraph capped at depth 10 | Prevents infinite recursion | + +## Evidence Standards + +All CLI evidence follows a confidence hierarchy. Use these standards when +citing evidence in reports or explanations. + +### Evidence Categories (triage output) + +| Category | Definition | Example | +|----------|-----------|---------| +| **Observation** | Direct deterministic fact from the backend. No `confidence` field. | "Section .text is executable, size 4096 bytes" | +| **Heuristic** | Rule-derived interpretation with explicit `confidence`. | "Suspicious API: VirtualAlloc (risk_score: 8, confidence: HIGH)" | +| **Unknown** | Explicit unresolved question at a specific address. | "Indirect call target at 0x402080 could not be resolved" | + +### Confidence Levels + +| Level | Meaning | When to cite | +|-------|---------|--------------| +| `HIGH` | Backend is certain about this result | Cite as fact | +| `MEDIUM` | Backend has reasonable confidence | Cite with qualification ("likely") | +| `LOW` | Backend made a best-guess | Cite only with explicit caveat | +| `UNKNOWN` | Backend could not determine | Present as an open question | + +### Agent Inferences + +When you synthesize multiple CLI observations into a conclusion, label it +explicitly as an agent inference. Never present an inference as a CLI fact. Use +language like: + +- "Based on the combination of X and Y, the agent assesses that..." +- "The CLI reports Z as a heuristic (confidence: MEDIUM). The agent interprets + this as consistent with..." +- "The CLI could not determine W.

Load this when writing +reports, presenting findings, or when the user challenges the certainty of your +conclusions. This reference defines the evidence hierarchy, confidence scoring +methodology, and the hard boundary between deterministic CLI evidence and agent +inference. + +## The Evidence Boundary + +The single most important concept in this skill: + +| Source | Nature | Scope | Label | +|--------|--------|-------|-------| +| CLI `data` fields | Deterministic facts | What the backend observed | "CLI evidence" | +| CLI `diagnostics` | Limitations and caveats | What the backend could NOT determine | "CLI diagnostic" | +| Agent synthesis | Interpretive conclusions | What the observations mean together | "Agent assessment" | + +**Never blur these categories.** Do not present an agent assessment as if it +came from the CLI. Do not cite a CLI diagnostic as if it were positive +evidence. The user (human or downstream agent) must always know which layer +produced each claim. + +## Evidence Hierarchy + +Evidence is ranked from strongest to weakest. Cite from the strongest available +level. + +### Tier 1: Deterministic Observations + +**Source:** `binary triage` → `data.observations[]`, or any CLI `data` field. + +**Properties:** +- Directly measured or enumerated by the backend. +- No `confidence` field (it is a fact, not an interpretation). +- Reproducible: the same binary + same backend = same result. + +**Examples:** +- "Section .text is 4096 bytes, flags: rx" +- "Function main at 0x401000, size 384 bytes" +- "Import: kernel32.dll!CreateFileW" +- "String at 0x403000: 'C:\\Users\\Public\\payload.exe'" + +**How to cite:** Present as an unqualified fact. "The binary imports +CreateFileW from kernel32.dll." + +### Tier 2: Rule-Derived Heuristics (HIGH confidence) + +**Source:** `binary triage` → `data.heuristics[]` with `confidence: "HIGH"`. +Also `binary suspicious-apis` matches with `confidence: "HIGH"`. + +**Properties:** +- Rule engine matched a pattern with strong signal-to-noise ratio. +- HIGH confidence means the pattern is unambiguous given the available + evidence. +- Still an interpretation — not a direct observation. + +**Examples:** +- "process-injection (confidence: HIGH) based on VirtualAlloc + + WriteProcessMemory + CreateRemoteThread chain" +- "network-communication (confidence: HIGH) based on socket, connect, send, + recv imports" + +**How to cite:** Present as a strong indicator with the method. "The API +combination suggests process injection capability (confidence: HIGH, based on +the VirtualAlloc → WriteProcessMemory → CreateRemoteThread import chain)." + +### Tier 3: Rule-Derived Heuristics (MEDIUM confidence) + +**Source:** `binary triage` → `data.heuristics[]` with `confidence: "MEDIUM"`. +Also `binary capability-map` entries at MEDIUM. + +**Properties:** +- Rule engine matched a pattern but with lower specificity. +- Could be a false positive or the evidence is ambiguous. +- Common with capability assessments based on limited evidence. + +**Examples:** +- "credential-access (confidence: MEDIUM) based on CredEnumerateW import" +- "cryptography (confidence: MEDIUM) based on CryptEncrypt import" + +**How to cite:** Present with explicit qualification. "The binary imports +CredEnumerateW, which is consistent with credential enumeration (confidence: +MEDIUM). This API is also used by legitimate credential managers." + +### Tier 4: Rule-Derived Heuristics (LOW confidence) + +**Source:** `binary triage` → `data.heuristics[]` with `confidence: "LOW"`. +Also `binary capability-map` entries at LOW. + +**Properties:** +- Weak signal. The pattern is ambiguous or the evidence is thin. +- May be noise. Use only to guide further investigation, not as a conclusion. + +**Examples:** +- "anti-debugging (confidence: LOW) based on a single IsDebuggerPresent import + with no supporting evidence" + +**How to cite:** Present with strong caveat. "One anti-debugging API +(IsDebuggerPresent) was detected, but with LOW confidence. This is common in +many legitimate applications and may be a compiler default. It is not evidence +of malicious intent on its own." + +### Tier 5: Unknowns + +**Source:** `binary triage` → `data.unknowns[]`, or any `null`/missing field in +CLI output. + +**Properties:** +- The backend could not determine this information. +- Explicit gaps — not failures. + +**Examples:** +- "Indirect call target at 0x402080 could not be resolved" +- "GetProcAddress at 0x403c10: runtime-resolved APIs unknown" + +**How to cite:** Present as an open question. "Seven functions are called +indirectly and their targets could not be resolved by static analysis. The +dynamic behavior of these call sites is unknown." + +### Tier 6: Agent Inferences + +**Source:** Your own synthesis. Not in any CLI output. + +**Properties:** +- Your interpretation of multiple pieces of evidence. +- May be correct or incorrect. Cannot be verified by the CLI alone. +- Must be clearly labeled as an agent inference. + +**Examples:** +- "The combination of process injection and credential access APIs suggests + this is a credential harvesting tool." +- "The function at 0x402000 appears to be a custom XOR decryption routine based + on the loop pattern and XOR constant." + +**How to cite:** Always label explicitly. "Based on the combination of X and Y, +the agent assesses that Z. This inference has not been verified by dynamic +analysis." + +## Confidence Scoring Methodology + +The CLI uses these confidence levels: + +| Level | Meaning | When Applied by Rules | +|-------|---------|----------------------| +| HIGH | Rule matched with strong, unambiguous evidence | Multiple corroborating indicators, no contradicting evidence | +| MEDIUM | Rule matched with reasonable but not conclusive evidence | Single strong indicator or multiple weak ones | +| LOW | Rule matched with weak or ambiguous evidence | Single weak indicator, or pattern known to produce false positives | +| UNKNOWN | Rule could not determine | Insufficient evidence to evaluate the rule | + +### How Rules Determine Confidence + +Rules in the rule engine combine: +- **Evidence count**: How many supporting indicators were found. +- **Evidence strength**: How specific each indicator is to the rule. +- **Contradicting evidence**: Whether any indicators point away from the rule. +- **False positive rate**: Historical (or conservatively estimated) noise level + for this pattern. + +For example, the `process-injection` rule: +- 3 APIs (VirtualAlloc, WriteProcessMemory, CreateRemoteThread) → HIGH +- 2 APIs (VirtualAlloc, WriteProcessMemory) → MEDIUM +- 1 API (CreateRemoteThread alone) → LOW +- Contradicting: binary also imports legitimate IPC APIs → confidence reduced + +### What Confidence Does NOT Mean + +- HIGH confidence does NOT mean the binary is malicious. It means the pattern + is unambiguous. +- LOW confidence does NOT mean the binary is benign. It means the evidence is + insufficient. +- UNKNOWN does NOT mean there's nothing there. It means the rules couldn't + evaluate. + +## Building an Evidence-Backed Argument + +When presenting findings, follow this structure: + +### 1. State the Evidence (Deterministic) + +"Here is what the CLI found." List observations from `data` blocks. Do not +interpret. + +### 2. State the Heuristics (Rule-Derived) + +"The rule engine identified these patterns." List heuristics with confidence +levels and the evidence that triggered them. + +### 3. State the Unknowns (Gaps) + +"The backend could not determine the following." List unknowns and their +addresses. + +### 4. State Your Assessment (Agent Inference) + +"Based on the above, I assess that..." Clearly separate this from the CLI +evidence. Use qualifying language: + +| Strength | Language | +|----------|----------| +| Strong | "The evidence shows", "The analysis confirms" | +| Moderate | "The evidence suggests", "This is consistent with" | +| Weak | "It is possible that", "One interpretation is" | +| Speculative | "The agent speculates that", "Without dynamic analysis, one cannot confirm" | + +### 5. Disclose Limitations + +"What we cannot determine from static analysis alone." List: +- Indirect call targets +- Runtime-resolved imports +- Encrypted/obfuscated regions +- Missing debug symbols +- Timeouts or partial results +- Backend capability limitations + +## Common Evidence Pitfalls + +### Pitfall 1: Confirming the Consequent + +**Wrong:** "The binary imports CreateRemoteThread, therefore it performs +process injection." + +**Right:** "The binary imports CreateRemoteThread (CLI evidence). The rule +engine flags this as process-injection with MEDIUM confidence (CLI heuristic). +The agent notes that import presence alone does not confirm the API is called +or with what parameters." + +### Pitfall 2: Overclaiming from Capability Map + +**Wrong:** "The binary has networking capability, so it exfiltrates data." + +**Right:** "The capability map suggests networking capability (confidence: +MEDIUM, based on WinHTTP imports). This means the binary CAN communicate over +HTTP. Whether it DOES, and what data it sends, cannot be determined by static +analysis alone." + +### Pitfall 3: Hiding Partial Results + +**Wrong:** Presenting findings without mentioning that 40% of functions timed +out during decompilation. + +**Right:** "Function analysis completed for 60 of 100 functions before a +timeout. The following findings are based on the 60 functions that completed. +The remaining 40 functions (listed in diagnostics) were not analyzed." + +### Pitfall 4: Presenting Inferences as Facts + +**Wrong:** "This is a ransomware binary." + +**Right:** "The binary imports cryptographic APIs (CryptEncrypt, +CryptAcquireContext) and file enumeration APIs (FindFirstFileW, +FindNextFileW). The agent assesses this combination is consistent with +ransomware behavior, but ransomware cannot be confirmed without dynamic +analysis showing actual file encryption." + +## Evidence Quality Checklist + +Before presenting findings, verify: + +- [ ] Every factual claim is traceable to a specific CLI `data` field. +- [ ] Agent assessments are explicitly separated from CLI evidence. +- [ ] Confidence levels are cited for every heuristic claim. +- [ ] Unknowns and limitations are disclosed, not buried. +- [ ] No claim of certainty where the CLI reports partial results or LOW + confidence. +- [ ] The binary SHA-256 is included (every claim ties back to a specific + binary). +- [ ] Provenance fields (adapter, backend, version) are available for + reproducibility. + +## Reporting Evidence + +When generating a formal report with `binary export-report`, the report +structure already separates evidence categories.

Multiple JDK versions can coexist; set `JAVA_HOME` to point at +the JDK 21 installation. + +Set the environment variable: + +```bash +# macOS (Homebrew) +export JAVA_HOME="/opt/homebrew/opt/openjdk@21/libexec/openjdk.jdk/Contents/Home" + +# Linux +export JAVA_HOME="/usr/lib/jvm/java-21-openjdk-amd64" + +# Windows (PowerShell) +$env:JAVA_HOME = "C:\Program Files\Eclipse Adoptium\jdk-21.0.0.35-hotspot" +``` + +Add this to your shell profile (`.zshrc`, `.bashrc`, or equivalent) for +persistence. + +### Step 2: Install Ghidra + +Download the latest Ghidra release from [ghidra-sre.org](https://ghidra-sre.org/). + +Extract to a stable location: + +```bash +# Recommended locations +mkdir -p ~/.local/opt/ghidra +# Extract the downloaded zip into this directory +# Result should be: ~/.local/opt/ghidra/ghidra_12.1.2_PUBLIC/ +``` + +Set the environment variable: + +```bash +export GHIDRA_INSTALL_DIR="$HOME/.local/opt/ghidra/ghidra_12.1.2_PUBLIC" +``` + +Verify the installation: + +```bash +ls "$GHIDRA_INSTALL_DIR"/support/analyzeHeadless +# Should print the path to the headless analyzer script +``` + +### Step 3: Install PyGhidra + +PyGhidra is the Python bridge that lets the `binary` CLI control Ghidra. + +**Option A: Manual pip install** + +```bash +pip install pyghidra +``` + +Verify: + +```bash +python -c "import pyghidra; print(pyghidra.__version__)" +``` + +**Option B: Automated bootstrap (recommended)** + +```bash +binary bootstrap --apply --json +``` + +This discovers missing dependencies, downloads and installs PyGhidra, and +verifies the installation with a checksum. It does NOT install Java or Ghidra — +those must be installed manually first. + +### Step 4: Verify the Full Toolchain + +```bash +binary doctor --json +``` + +Expected output when everything is healthy: + +```json +{ + "success": true, + "diagnostics": [ + {"severity": "INFO", "component": "java", "message": "JDK 21.x.x found at ..."}, + {"severity": "INFO", "component": "ghidra", "message": "Ghidra 12.1.x found at ..."}, + {"severity": "INFO", "component": "pyghidra", "message": "PyGhidra 3.1.x found"} + ] +} +``` + +Run the version command for a full component report: + +```bash +binary version --json +``` + +Expected output includes `cli_version`, `adapter` (name + version), `backend` +(name + version), and `platform`. + +## Using the Doctor for Diagnostics + +The `binary doctor` command checks each component and reports diagnostics: + +```bash +binary doctor --json +``` + +### Understanding Doctor Output + +Each diagnostic entry has: +- `severity`: `INFO` (healthy), `WARNING` (suboptimal), or `ERROR` (missing/broken) +- `component`: `java`, `ghidra`, or `pyghidra` +- `message`: Human-readable status +- `remediation`: Specific steps to fix the issue + +### Common Doctor Errors + +| Message | Cause | Fix | +|---------|-------|-----| +| `java: not found` | Java not on PATH | Install JDK 21+ and set JAVA_HOME | +| `ghidra: GHIDRA_INSTALL_DIR not set` | Env var missing | Export GHIDRA_INSTALL_DIR | +| `ghidra: analyzeHeadless not found` | Wrong path or incomplete extraction | Verify extraction completed; check for `support/analyzeHeadless` | +| `pyghidra: import failed` | PyGhidra not installed or wrong Python | `pip install pyghidra` in the active venv | +| `pyghidra: version too old` | PyGhidra < 3.1 | `pip install --upgrade pyghidra` | + +### Programmatic Readiness Check + +Use `--require-ready` for scripting or CI gates: + +```bash +binary doctor --require-ready --json +``` + +Exits with code 0 only if every component is present and verified. Otherwise +exits with code 3 (DEPENDENCY_MISSING). + +## Bootstrap: Automated PyGhidra Setup + +The bootstrap command handles PyGhidra installation. It does NOT install Java or +Ghidra — those require manual or system-package-manager installation. + +### Plan Mode (No Changes) + +```bash +binary bootstrap --plan --json +``` + +Shows what would be installed without making changes. Output includes each +component's `name`, `status` (`missing` or `present`), `action` (`install` or +`skip`), and `source`. + +When all dependencies are present: + +```json +{ + "success": true, + "data": { + "components": [ + {"name": "java", "status": "present", "action": "skip"}, + {"name": "ghidra", "status": "present", "action": "skip"}, + {"name": "pyghidra", "status": "present", "action": "skip"} + ] + } +} +``` + +### Apply Mode (Installs) + +```bash +binary bootstrap --apply --json +``` + +Downloads and installs PyGhidra, verifies the installation, and reports results. +Each component has a `status` of `installed` or `failed`.

It is evidence collection organized into three +canonical categories: + +1. **Observations**: Direct, deterministic facts from the backend. No + interpretation. No `confidence` field.

Go straight to focused analysis. +- The binary is already well-understood and you're checking a specific + hypothesis. + +## Triage Workflow (Step by Step) + +### Step 1: Environment and Project Setup + +Before touching the binary, verify the toolchain and create an isolated +workspace. + +```bash +# Verify tools are available +binary doctor --json + +# Create a project (name it after the binary or analysis purpose) +binary project create triage- --json + +# Import in copy mode (default) for reproducibility +binary import /path/to/binary --project triage- --json +``` + +**Check the import response:** +- `import_mode`: "copy" means the sample is isolated. Good. +- `binary_sha256`: Record this. It's your evidence anchor — every finding ties + back to this hash. +- `format`: If "RAW", note this. Raw-format triage follows a different path + (see Step 6). + +**If import returns `success: false`:** +- Exit code 5 (UNSUPPORTED_FORMAT): The file is not a recognized executable + format. Skip to Step 6 for RAW triage. +- Exit code 10 (IMPORT_FAILED): Backend could not load the file. Check + diagnostics. The file may be corrupted. + +### Step 2: Analysis Profile Selection + +```bash +binary analyze --project triage- --profile standard --json +``` + +| Profile | When to Use | Time Estimate | +|---------|-------------|---------------| +| `standard` | Default. Covers all structural queries needed for triage. | ~30s-2min | +| `quick` | Large binary (>50MB) or time-constrained. Skips deep function analysis. | ~10s-30s | +| `deep` | Focused security review. Runs all analyzers including data-flow. | ~2min-10min | + +**Check the analyze response:** + +- `success: true, partial: false` → Proceed to Step 3. +- `success: true, partial: true` → Review diagnostics. Note which analyzers + failed. Proceed with bounded results — they are still evidence. +- `success: false, partial: true` → Timeout (exit code 12). The binary may be + very large or contain deeply nested control flow. Try `--profile quick` or + increase `--timeout`. +- `success: false, partial: false` → Hard failure (exit code 11). Check + diagnostics. The project is now FAILED. Run `binary project clean` to reset. + +### Step 3: Run the Automated Triage + +```bash +binary triage --project triage- --json +``` + +The triage command runs the rule engine against backend data and produces the +three-category output. This is your primary evidence source. + +**Read the triage output systematically:** + +#### 3a. Review Observations (`data.observations[]`) + +Observations are bare facts. Scan for: + +- **Entry point characteristics**: Address, section location. Is the entry + point in `.text` (normal) or an unusual section? +- **Section layout**: Count, names, flags. Note any RWX sections immediately. +- **Import count and sources**: How many DLLs/libs? Which ones? +- **Export count**: Does this binary export functions? (It may be a library or + have plugin capabilities.) +- **String density and categories**: Many error strings? URLs? File paths? + Registry keys? +- **Compiler/package identification**: Strings like "GCC:", "MSVC", "Go build + ID", "rustc" identify the toolchain. + +#### 3b. Review Heuristics (`data.heuristics[]`) + +Heuristics are rule-derived interpretations. Each has a `confidence` score. + +**Sort by risk and confidence:** +- HIGH confidence + high risk_score → Flag prominently in your assessment. +- LOW confidence + high risk_score → Flag as "possible" with explicit caveat. +- HIGH confidence + low risk_score → Note but don't overstate. +- LOW confidence + low risk_score → Typically noise. Acknowledge but don't + center your assessment on it. + +**Common heuristic categories:** +- **API-based**: Suspicious API combinations (process injection, credential + access, network enumeration). +- **Structure-based**: Unusual section flags, high entropy, missing imports. +- **Capability-based**: Networking, cryptography, file system, keylogging, + anti-debugging. +- **Compilation-based**: Packer signatures, known compiler fingerprints, debug + build indicators. + +#### 3c. Review Unknowns (`data.unknowns[]`) + +Unknowns are specific gaps — things the backend could not resolve: + +- **Indirect call targets**: `call eax` where the target is computed at + runtime. The backend can't follow this. +- **Unresolved imports**: Symbols resolved via `GetProcAddress`/`dlsym`. +- **Encrypted/obfuscated regions**: Areas the decompiler couldn't penetrate. + +Each unknown has an `address` and a `question`. These are your todo list for +deeper analysis — each one is a candidate for `binary decompile` or `binary +disassemble`. + +### Step 4: Follow Up with Focused Analysis + +The triage output tells you where to dig deeper. Prioritize: + +1. **High-confidence suspicious heuristics** → Run `binary suspicious-apis` for + detailed API risk scoring. +2. **High-confidence capability heuristics** → Run `binary capability-map` to + map functional areas with evidence sources. +3. **Unresolved unknowns at key addresses** → Run `binary decompile` or + `binary disassemble` on the surrounding function. +4. **Unusual import patterns** → Run `binary imports` for full resolution + status, then `binary callees` on suspicious functions. +5. **Interesting strings** → Run `binary xrefs` on the string's address to + find which code references it. + +```bash +# Deepen API analysis +binary suspicious-apis --project triage- --json + +# Map capabilities with evidence +binary capability-map --project triage- --json + +# Investigate a specific function +binary decompile --project triage- function: --json +binary xrefs --project triage- function: --json +binary callers --project triage- function: --json +binary callees --project triage- function: --json +``` + +### Step 5: Check Diagnostics + +Always review diagnostics before presenting findings: + +```bash +binary diagnostics --project triage- --json +``` + +Diagnostics reveal: +- **Timeouts**: Some analyzers didn't finish. Your results are incomplete. +- **Backend limitations**: Certain analyses aren't supported for this format or + architecture. +- **Partial failures**: Specific modules failed but analysis continued. +- **Memory or output limits**: Results were truncated. + +**Never silently ignore diagnostics.** If a diagnostic says "function analysis +incomplete for 5 of 200 functions," mention this when you present the function +count. Incomplete evidence is still evidence, but it must carry that caveat. + +### Step 6: RAW Format Triage + +When `binary metadata` reports `format: "RAW"`, the standard triage workflow +may produce limited results. Adjust: + +1. **String analysis is your primary tool:** + + ```bash + binary strings --project triage- --min-length 6 --json + ``` + + Scan for: + - Compiler/OS identification strings + - Error messages (reveal functionality) + - URLs, IP addresses, file paths + - Function names from stripped debug info + - Format signatures (maybe it's a known container format) + +2. **Entropy analysis via `binary sections`:** + + High entropy across the entire file → compressed or encrypted. Low entropy + with visible strings → flat firmware or raw code. + +3. **Byte-level analysis:** + + ```bash + binary bytes --project triage- 0x0 256 --json + ``` + + Look at the first 256 bytes for any magic bytes or structure. + +4. **Check for known firmware formats** (see [firmware.md](firmware.md)). + +5. **Check for packing** (see + [packed-and-obfuscated.md](packed-and-obfuscated.md)). + +6. If nothing works, report the RAW format, file size, entropy, and any + identifiable strings. Flag as `unknown` with the file's physical + characteristics. + +### Step 7: Synthesize Findings + +After collecting all evidence, synthesize it into a human-readable assessment. +**This is your (the agent's) work — not the CLI's output.** + +Structure your synthesis: + +``` +## CLI Evidence + +### Binary Identity +- Format: PE, x86-64, 45,632 bytes +- SHA-256: +- Compiled: 2024-03-15 (PE timestamp) +- Compiler: MSVC 19.35 (from .rdata strings) + +### Structural Observations +- 3 sections: .text (rx), .rdata (r), .data (rw) +- Entry point: 0x140001000 (.text) +- 47 imports from 5 DLLs +- 12 exports (DLL project) + +### Security Heuristics +- process-injection (risk_score: 8, confidence: HIGH) + Evidence: VirtualAlloc + WriteProcessMemory + CreateRemoteThread +- credential-access (risk_score: 6, confidence: MEDIUM) + Evidence: CredEnumerateW, CryptUnprotectData + +### Unknowns +- Indirect call at 0x140002a80: target not statically resolvable +- GetProcAddress call at 0x140003c10: runtime-resolved APIs unknown + +## Agent Assessment + +The binary is a DLL that exhibits API patterns consistent with process +injection (confidence: HIGH based on the VirtualAlloc → WriteProcessMemory → +CreateRemoteThread chain) and possible credential harvesting (confidence: +MEDIUM based on DPAPI decryption APIs). The binary uses MSVC and was likely +compiled in early 2024. + +Limitations: Several calls are resolved at runtime via GetProcAddress, +meaning the static analysis cannot determine their targets. The +credential-access assessment is based on API presence, not confirmed behavior. +Dynamic analysis would be needed to confirm. +``` + +## Triage Red Flags (Immediate Action Items) + +Some findings should be flagged immediately, even before completing the full +triage: + +| Finding | Action | +|---------|--------| +| RWX section | Flag as suspicious.

Only the unpacking stub is visible. + +4. **Empty result is valid**: The binary genuinely has no exports, or no + strings matching the filter. An empty `data.exports[]` is valid for an EXE + (as opposed to a DLL). + +5. **Filter too restrictive**: `--min-length` or `--contains` may exclude all + results. + ```bash + # Try with relaxed filters + binary strings --project --min-length 4 --json + ``` + +### Issue: Decompilation Timeout + +**Symptoms:** +- `binary decompile` returns exit code 12 (OPERATION_TIMEOUT). +- `success: false, partial: true`. +- Diagnostic mentions timeout. + +**Resolution:** + +1. **Increase timeout:** + ```bash + binary decompile --project function: --timeout 600 --json + ``` + +2. **The function may be very large** (thousands of basic blocks). Try + disassembly instead: + ```bash + binary disassemble --project function: --limit 200 --json + ``` + +3. **The function may contain pathological control flow** (e.g., computed + goto with hundreds of targets). Note this as a limitation and analyze what + the decompiler produced before the timeout. + +### Issue: Corrupted Project Manifest + +**Symptoms:** +- `binary project status` exits with code 4 (INVALID_CONFIG). +- Error mentions "corrupted manifest" or "invalid project.json". +- Manual inspection shows `project.json` is truncated or contains invalid JSON. + +**Resolution:** + +If the project has no valuable data (no reports, no completed analysis): +```bash +binary project remove --yes --json +binary project create --json +``` + +If the project has reports you want to preserve, copy them from +`/reports/` before removing, then recreate the project. + +### Issue: "Unsupported Format" on Known Binary + +**Symptoms:** +- `binary import` exits with code 5 (UNSUPPORTED_FORMAT) on a file you believe + should be supported. +- The file might be a PE, ELF, or Mach-O but with unusual characteristics. + +**Diagnosis:** + +1. Check the file with system tools: + ```bash + file /path/to/binary + xxd /path/to/binary | head -4 + ``` + +2. Possible causes: + - The file is a corrupt or truncated download. + - The file is a self-extracting archive (SFX) which looks like a PE but + contains compressed data. + - The file is a firmware blob wrapped in a proprietary header. The PE/ELF + may be embedded at a non-zero offset. + - The file is a non-standard variant (e.g., WinCE PE which has different + magic). + +### Issue: Permission Denied + +**Symptoms:** +- Error mentioning "permission denied" or "EACCES". +- Typically on project creation, import, or write operations. + +**Resolution:** +- Check that the workspace directory is writable: + ```bash + ls -la ~/.local/share/binary-analysis/workspaces/ + ``` +- Check that the source binary is readable: + ```bash + ls -la /path/to/binary + ``` +- Check disk space: + ```bash + df -h ~/.local/share/binary-analysis/ + ``` + +## Ghidra-Specific Issues + +### Issue: "Ghidra already running" or Port Conflict + +**Symptoms:** +- Error about port already in use, or Ghidra fails to start a new instance. + +**Resolution:** +Ghidra may have a stale process from a previous run. +```bash +ps aux | grep ghidra +ps aux | grep java | grep ghidra +``` +If you find stale Ghidra JVM processes and you're sure no analysis is active, +terminate them. Be careful not to kill unrelated Java processes. + +### Issue: "Unsupported processor" or Architecture Error + +**Symptoms:** +- Error about unsupported language or processor module. + +**Cause:** +Ghidra does not support the target architecture (rare for mainstream +architectures; more common for exotic embedded CPUs). + +**Resolution:** +- Check the architecture in `binary metadata` output. +- Verify Ghidra supports it: check `$GHIDRA_INSTALL_DIR/Ghidra/Processors/` + for the processor module. +- If unsupported, note the limitation and stop. Do not attempt to force + analysis with the wrong architecture — results will be nonsense. + +## Worker Issues + +### Issue: Worker Fails to Start + +```bash +binary worker start --json +``` + +If `success: false`: +- Check that no other worker is already running: `binary worker status --json` +- The worker socket path may be inaccessible. Check permissions on the socket + directory. +- All commands still work without the worker (one-shot mode) — the worker is + an optimization, not a requirement. + +### Issue: Worker Stale After Client Crash + +If a client crashed while using the worker: +```bash +binary worker stop --json +binary worker start --json +``` +Stop is idempotent and will clean up the stale worker. + +## System-Level Issues + +### Issue: Out of Memory + +**Symptoms:** +- Process killed by OOM killer. +- Error about "Cannot allocate memory". +- System becomes unresponsive during large analysis. + +**Resolution:** +- Close other memory-intensive applications. +- Use `--profile quick` instead of `standard` or `deep`. +- Use `--max-memory` flag to cap the JVM heap: + ```bash + binary analyze --project --max-memory 2147483648 --json # 2GB + ``` + +### Issue: Disk Space Exhaustion + +**Symptoms:** +- Error writing to project directory. +- Copy-mode import fails. + +**Resolution:** +- Use `--reference` mode for large binaries to avoid copying into the project. +- Clean up old projects: `binary project list --json` → identify stale + projects → `binary project remove --yes`. +- Check disk usage: `du -sh ~/.local/share/binary-analysis/` + +## When to Give Up and Escalate + +Stop troubleshooting and escalate when: + +1. **Three attempts at the same operation produce the same error** — you're + hitting a reproducible bug, not a transient condition. Report the error + with the exact command, exit code, and diagnostics. +2. **The binary format is genuinely unsupported** (exit code 5) after verifying + the file is not corrupt. +3. **A hard dependency is missing and the user declines to install it** — + report the gap. +4. **The binary causes Ghidra to crash consistently** — this may indicate an + anti-analysis construct or a Ghidra bug. Report the binary SHA-256, file + size, and the crash error. +5. **Results are nonsensical across multiple commands** — e.g., all functions + decompiled to "undefined", all addresses reported as invalid.

summaries, analysis, and evidence dossiers. Use when producing multi-layer research artifacts or coordinating research handoffs. - [autogen](autogen/SKILL.md): Expert skill for conversational multi-agent AI with Microsoft AutoGen. AssistantAgent, UserProxyAgent, GroupChat, code execution, nested chats, cancellation tokens, tool integration, and MCP support. Use when building conversation-driven multi-agent systems or comparing agent frameworks. - [backend-engineering](backend-engineering/SKILL.md): Backend engineering methodology — API implementation patterns (REST, gRPC, GraphQL), service architecture (clean/hexagonal/layered), database access patterns, integration and middleware design, error handling, and service-level testing. Language and framework agnostic. +- [binary-analysis](binary-analysis/SKILL.md): Analyze unknown binary files through a deterministic CLI that wraps Ghidra's static-analysis engine. Use when you need to inspect a PE, ELF, or Mach-O file — triage suspicious binaries, map imported APIs, decompile functions, trace call paths, or produce structured evidence reports. Do not use for runtime analysis (debugging, dynamic tracing, sandbox execution), for modifying or patching binaries, or for binaries you already know everything about. The skill owns planning, hypothesis formation, and evidence synthesis; the CLI owns all deterministic operations. - [brand-designer](brand-designer/SKILL.md): Create comprehensive brand identity documentation for any brand. Guides you through documenting strategy, visual identity (logo, color, typography, imagery), voice and tone, application guidelines, governance, and asset inventory. Produces markdown specs, compiled brand books, and brand-compliant images via reference-image-aware generation. Use when you need to capture a brand's identity in structured, durable form — for vault storage, agency handoff, or press kit distribution. - [c4-diagramming](c4-diagramming/SKILL.md): Create C4 software-architecture diagrams using Mermaid or Structurizr. Use when teams need clear system context, container, component, or code-level views. - [chief-of-staff-methodology](chief-of-staff-methodology/SKILL.md): Prepare accountable executive decisions, information triage, briefing, calendar choices, organizational sensing, and institutional memory without assuming authority or monitoring people. Use when a chief of staff or CoS, executive office, gatekeeping, decision memo, executive briefing, board materials, organizational sensing, team health, institutional memory, calendar triage, meeting audit, strategic time, or attention allocation is requested. diff --git a/pyproject.toml b/pyproject.toml index 22f21e7..0a4ca6b 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -97,6 +97,7 @@ cc_min = "B" requirements_files = ["requirements-dev.txt"] extend_exclude = [ "agent-council", + "binary-analysis", "bundles", "templates", "tests", diff --git a/scripts/check-artifacts.py b/scripts/check-artifacts.py index 43bc337..877be22 100644 --- a/scripts/check-artifacts.py +++ b/scripts/check-artifacts.py @@ -68,9 +68,13 @@ def run_checks(files: list[Path]) -> list[str]: for directory in test_directories(files): relative = directory.relative_to(ROOT) + before = set(sys.modules) result = unittest.TextTestRunner(verbosity=0).run( unittest.defaultTestLoader.discover(str(directory), top_level_dir=str(directory)) ) + for mod in list(sys.modules): + if mod not in before: + del sys.modules[mod] if not result.wasSuccessful(): errors.append( f"unittest discover {relative}: "
