# Fuzzer — HTTP/AI Adversarial Testing Tool
CLI fuzzer for authorized security testing of HTTP endpoints and AI/LLM APIs. Put `{{FUZZ}}` anywhere in a request and it handles the rest: auth flows, payload delivery, response analysis, and reporting.
## Install
```bash
pip install requests pyyaml
```
## Quick Start
```bash
# Generate starter configs
python fuzzer.py --gen-templates configs
# Run against a target
python fuzzer.py -c configs/simple_post.yml -w wordlists/payloads.txt -o results.log
# Single payload
python fuzzer.py -u https://api.example.com/query -b '{"q": "{{FUZZ}}"}' -p "test payload"
```
## Placeholders
| Placeholder | Replaced with |
|---|---|
| `{{FUZZ}}` | Each payload from your wordlist |
| `{{AUTH}}` | Bearer token after the auth step runs |
| `{{KEY}}` | Any key from your vars file — `{{TOKEN}}`, `{{USERNAME}}`, etc. |
Put them anywhere: URL, headers, body.
## Config File
```yaml
name: "My Test"
auth:
url: "https://auth.example.com/oauth2/token"
token_field: "access_token"
cache: 280
request:
url: "https://api.example.com/v1/query"
method: POST
headers:
Authorization: "Bearer {{AUTH}}"
Content-Type: "application/json"
body: '{"prompt": "{{FUZZ}}"}'
fuzz_encoding: json
settings:
timeout: 30
delay: 0.1
```
## Vars File
A flat `KEY=VALUE` file. Keeps credentials out of configs.
```env
TOKEN=your-token-here
USERNAME=testuser
PASS=testpass
```
Pass with `-e configs/vars.env` or let it auto-discover `vars.env`.
## Key Flags
```
-w FILE Wordlist (one payload per line)
-p TEXT Single payload
-l 1-4 Batch mode: run level 1-4 wordlist directory
-c FILE Config file
-u URL Target URL (CLI mode)
-b BODY Request body template
-H 'Name: V' Add header (repeatable)
-e FILE Vars file
-o FILE Output log (default: fuzzer_output.log)
--threads N Concurrent workers (default: 1)
--delay N Seconds between requests
--proxy URL Route through proxy (e.g. Burp: http://127.0.0.1:8080)
--skip N Skip first N payloads (resume)
--max N Stop after N payloads
--report FILE Write HTML/JSON/CSV report
--debug Show full request/response exchange
```
## Batch Mode (Wordlist Levels)
Organize wordlists into level directories under `--wordlist-dir`:
```
wordlists/
level-1-essential/ # Quick baseline
level-2-standard/ # Broader coverage
level-3-advanced/ # Deep testing
level-4-comprehensive/ # Full coverage
labeled/ # Technique:payload format for exact tracking
```
```bash
# Run all categories at level 1
python fuzzer.py -l 1 -c config.yml -o results.log
# Specific categories only
python fuzzer.py -l 1 --categories 07 08 -c config.yml
# Level 2, route through Burp
python fuzzer.py -l 2 -c config.yml --proxy http://127.0.0.1:8080
```
## Authentication
Supports OAuth2 client credentials, session/cookie auth, API key headers, and custom auth flows. The `{{AUTH}}` placeholder is auto-filled after each auth cycle, and tokens are cached for the duration specified in `auth.cache`.
See `configs/oauth2.yml` and `configs/session_auth.yml` for examples.
## Response Flagging
Flag responses by status code, body content, or size:
```bash
--flag-status 200 403 # Flag these status codes
--flag-contains "error" # Flag responses containing text
--flag-not-contains "deny" # Flag responses missing text
--flag-size-min 1000 # Flag responses over 1000 bytes
```
Flagged responses are highlighted in terminal output and separated in reports.
## Log Analysis
Analyze an existing log file without re-running the fuzzer:
```bash
python fuzzer.py --analyze results.log
python fuzzer.py --analyze results.log --analyze-html report.html
```
## Multi-Turn Sequences
Chain requests for conversation-based testing:
```bash
python fuzzer.py --sequences sequences_example.json --sequence "jailbreak-chain" -c config.yml
```
## Other Features
- **OpenAPI discovery**: `--openapi spec.yaml` — parse endpoints, auto-generate configs
- **Burp import**: `--burp-import burp-export.xml` — use a Burp-captured request as the target
- **Payload mutation**: `--mutate encoding` — auto-generate encoding variants (base64, URL, unicode, etc.)
- **Combinator**: `--prefix-file p.txt --suffix-file s.txt --combine` — combine prefix+payload+suffix
- **Checkpoint/resume**: saves state automatically, `--skip N` to resume
- **Deduplication**: `--dedupe-file results.log` — remove duplicate responses from a log
- **Jitter**: `--jitter` — randomize timing between requests
- **UA rotation**: `--rotate-ua` — cycle User-Agent headers
## Authorization
For authorized security testing only. Always obtain written scope authorization before testing any system you don't own.
