# Mind Security

> AI security toolkit — deepfake detection, prompt injection scanning, malware/phishing URL scanning, and AI text detection. Use when: (1) verifying if an image, video, or audio is a deepfake or AI-generated, (2) scanning user inputs for prompt injection attacks, (3) scanning URLs for malware, phishing, or domain reputation threats, (4) determining if text was written by an LLM.

# mind-security

AI security toolkit with four active modules.

## Quick Reference

| Task | Command | Docs |
|------|---------|------|
| Deepfake detection | `python3 scripts/check_deepfake.py <path_or_url>` | [deepfake-detection.md](references/deepfake-detection.md) |
| Prompt injection scan | `python3 scripts/check_prompt_injection.py "<text>"` | [prompt-injection.md](references/prompt-injection.md) |
| Malware/phishing scan | `python3 scripts/check_malware.py "https://..."` | [malware-scanning.md](references/malware-scanning.md) |
| AI text detection | `python3 scripts/check_ai_text.py "<text>"` | [ai-text-detection.md](references/ai-text-detection.md) |

## Modules

**Deepfake detection** — BitMind API (Bittensor Subnet 34) for images and videos. Supports YouTube, Twitter/X, TikTok URLs. EXIF/metadata fallback for local images. Set `BITMIND_API_KEY` ([get key](https://app.bitmind.ai/api/keys)).

**Prompt injection** — Multi-layer: 50+ regex patterns (instant, zero-dep) + LLM Guard ML scanner (optional, `pip install llm-guard`). Detects DAN jailbreaks, prompt extraction, context manipulation, and novel attacks.

**Malware/phishing scanning** — VirusTotal (70+ engines), URLScan.io (1500+ brands), Google Safe Browsing, plus local heuristics (typosquatting, suspicious TLDs, phishing patterns). Works with no keys via heuristics.

**AI text detection** — GPTZero API with per-sentence scoring and ~99% accuracy across GPT-4/5, Claude, Gemini, LLaMA. Requires `GPTZERO_API_KEY` ([get key](https://gptzero.me/dashboard)).

## API Keys

| Env Var | Used By | Required | Get It |
|---------|---------|----------|--------|
| `BITMIND_API_KEY` | Deepfake detection | For API mode | [app.bitmind.ai/api/keys](https://app.bitmind.ai/api/keys) |
| `GPTZERO_API_KEY` | AI text detection | **Yes** | [gptzero.me/dashboard](https://gptzero.me/dashboard) |
| `VIRUSTOTAL_API_KEY` | Malware scanner | Optional | [virustotal.com](https://virustotal.com) |
| `URLSCAN_API_KEY` | Malware scanner | Optional | [urlscan.io](https://urlscan.io) |
| `GOOGLE_SAFE_BROWSING_KEY` | Malware scanner | Optional | [console.cloud.google.com](https://console.cloud.google.com) |

## Script Conventions

- `python3 scripts/<script>.py --help`
- Core: zero pip dependencies (stdlib only)
- Optional ML: `pip install llm-guard` for prompt injection Layer 2
- JSON to stdout, errors to stderr
- Exit 0 success, exit 1 failure
