SneakyScope

A lightweight web-based sandbox for analyzing websites and domains. SneakyScope fetches a page in a sandbox, enriches with WHOIS/GeoIP, and runs a unified Rules Engine (YAML + function rules) against scripts, forms, and text. Results are saved per-run and rendered with analyst-friendly tables, severity badges, and tags. Results are saved at time of analysis per run so you have a point in time result that doesn't change.

Repo: https://git.sneakygeek.net/ptarrant/SneakyScope Status: Private (may become public later)

🚀 Features

Unified Detection (Rules Engine)

• Regex rules from YAML + function rules in code for context-aware checks.

• PASS/FAIL per rule with reason, severity (low|medium|high), and tags.

• Per-script matches:

  • Inline scripts → run regex rules on the code.
  • External scripts → run function rules with structured facts (src, hostnames, etc.).

• Page-level overview: complete PASS/FAIL tables by category (script, form, text).

Domain & IP Enrichment

• WHOIS with robust fallbacks (N/A, Possible Privacy when fields are missing).
• GeoIP, ASN, and ISP details.

Results & UX

• Per-run artifacts under /data/<uuid>/:

  • screenshot.png, source.txt, results.json (single source of truth).

• Suspicious Scripts table shows only matched scripts with:

  • Severity badges and tag chips (tooltip shows rule reason).
  • Snippet preview length configurable via settings.yaml.

🧱 Architecture at a Glance

• Flask app (Gunicorn in Docker)
• Playwright for headless page fetch/render
• BeautifulSoup4 for parsing
• Rules Engine
  • YAML regex rules (config/suspicious_rules.yaml)
  • Function rules (app/rules/function_rules.py) registered on startup
• Artifacts: persistent path mounted at /data (configurable)

⚙️ Setup

1) Clone

Since this repo is private, you’ll need credentials (HTTPS with a personal access token) or SSH access.

HTTPS (with token):

git clone https://git.sneakygeek.net/ptarrant/SneakyScope.git
cd SneakyScope

SSH:

git clone git@git.sneakygeek.net:ptarrant/SneakyScope.git
cd SneakyScope

2) Configure Environment

Copy and edit env:

cp .env.example .env

Important vars:

• SECRET_KEY – Flask secret (set in production).
• MAXMIND_LICENSE_KEY – for GeoIP (optional if you disable GeoIP).
• SNEAKYSCOPE_RULES_FILE – override path to YAML rules (optional).

3) Settings

settings.yaml controls UI/behavior. Example:

app:
  name: "SneakyScope"
  version_major: 0
  version_minor: 1

ui:
  snippet_preview_len: 160  # controls inline script snippet length in UI

4) Run with Docker Compose

docker-compose up --build

This builds the image and starts the web app. The /data directory in the container is where run artifacts are written—mount a host directory in Compose to persist between restarts.

🧪 Using SneakyScope

1. Open the web UI and submit a URL.

2. On completion you’ll see:

   • URL Overview (with permalink to /results/<uuid>)
   • Enrichment (WHOIS/GeoIP)
   • Redirects
   • Forms (inputs + per-form rule checks)
   • Suspicious Scripts (only scripts that matched rules; badges/tags, snippet)
   • Screenshot and Source

Artifacts for each run live under /data/<uuid>/:

• results.json – complete structured result consumed by the UI.
• source.txt, screenshot.png, and other files as added.

---

📝 Rules

YAML (regex) Rules

config/suspicious_rules.yaml contains regex rules (compiled IGNORECASE). Example:

- name: eval_usage
  description: "Use of eval() in script"
  category: script
  type: regex
  pattern: '\beval\s*\('
  severity: high
  tags: [obfuscation, unsafe-eval]

Function Rules (code)

Rules needing context (e.g., compare action host to page host) live in:

• app/rules/function_rules.py:

  • FactAdapter – converts snippets to structured facts.

  • FunctionRuleAdapter – lets dict-expecting rules run from engine inputs.

  • Implementations like:

    • form_action_missing
    • form_http_on_https_page
    • form_submits_to_different_host
    • script_src_uses_data_or_blob
    • script_src_has_dangerous_extension
    • script_third_party_host

They’re registered at startup in app/__init__.py alongside YAML rules.

🔧 Configuration Tips

• Snippet length: tweak ui.snippet_preview_len in settings.yaml (default 160).
• Rules file override: set SNEAKYSCOPE_RULES_FILE=/path/to/your.yaml.
• Artifacts path: by default /data in the container (mount via Compose).

🧭 Roadmap (short version)

Full details: docs/roadmap.md

• Core Analysis / Stability

  • Opt-in fetch external scripts (size/time limits) and evaluate fetched content.
  • Remove remaining legacy form “flagged_reasons” once function rules cover them.
  • Unit tests: YAML compilation, adapters, per-artifact rule cases.

• API Layer

  • Endpoints: /screenshot, /source, /analyse
  • OpenAPI at /api/openapi.yaml; docs at /docs (Swagger/Redoc)

• UI / UX

  • Auto-prepend http(s):///www. for bare domains
  • Source viewer (embedded editor)
  • Scripts table toggle: “Only suspicious” / “All scripts”
  • Rules Lab (WYSIWYG tester) for rapid rule validation

• Artifact Management & Ops

  • Retention/cleanup policy (age/size)
  • Periodic maintenance scripts (configurable in settings.yaml)
  • Results caching UX (re-run vs. load from cache)

• Extras / Integrations

  • Bulk URL analysis
  • Alerting/webhooks (Slack/email)
  • Analyst verdict tags + export (CSV/JSON)
