KAPLAN — Stealthy Bulk Fetching Over Tor for Red Team Ops

A multithreaded, identity-rotating, resilient file fetcher built for covert red team reconnaissance and data exfiltration over Tor.

🕵️‍♂️ Why This Tool Exists

When you're operating in hostile environments—whether during internal pentests, adversary simulations, or covert intel gathering—you can't afford to leave traces. Every HTTP request is a potential fingerprint. Every static IP is a liability.

Enter KAPLAN (tdd): a Python utility engineered for red teams who need to download sensitive documents, dumps, configs, or artifacts—anonymously, resiliently, and without revealing their true origin.

Unlike generic downloaders, tdd:

• Routes all traffic over Tor using SOCKS5.
• Rotates Tor circuits before every download to avoid linkability.
• Handles failures gracefully with exponential retry logic.
• Supports parallelized bulk fetching without breaking operational security.
• Leaves zero forensic residue beyond Tor traffic.

⚠️ Note: This tool is for authorized security research and legitimate red team engagements only. Misuse is illegal.

🧰 Key Features

Feature	Red Team Value
Automatic Tor Circuit Rotation	Each file download originates from a fresh exit node, preventing correlation between requests.
Parallelized Downloads (Threaded)	Speed meets stealth—download dozens of files concurrently without sacrificing anonymity.
Resilient Retry Logic	Handles timeouts, transient errors, and flaky onion services with configurable retries.
OPSEC-Aware Logging	All activity is timestamped, structured, and saved locally—no external telemetry.
Filename Extraction & Conflict Avoidance	Automatically parses Content-Disposition, falls back to URL-derived names, and prevents overwrites.
Tor Connectivity Validation	Before anything runs, tdd verifies your traffic is actually routed through Tor (via check.torproject.org).

🛠️ How It Works

1. Setup & Validation

• Starts by checking if Tor is properly routing traffic.
• If not, it warns you—because there’s nothing worse than thinking you’re anonymous when you’re not.

2. Input Handling

• Reads URLs from a simple urls.txt file:

  http://example.com/confidential.pdf
  http://example.com/creds.xlsx
  https://example.com/api/logs.zip

• Ignores comments (#) and invalid lines.

3. Download Execution

For each URL:

• 🔄 Rotates Tor identity (requests a new circuit via NEWNYM).
• 📥 Fetches the file via requests over socks5h:// (ensures DNS resolution happens over Tor).
• 📂 Saves with smart naming to avoid collisions.
• 📊 Logs success/failure with full context.

4. Execution Modes

• parallel (default): Uses ThreadPoolExecutor for speed.
• sequential: Slower, but useful for resource-limited or highly sensitive ops.

💻 Quick Start

Prerequisites

• Tor running with ControlPort 9051 and SOCKS5 at 9050 (default in most configs).
• Python 3.7+
• Install dependencies:

  pip install requests stem

Usage

1. Create urls.txt with your target files:

   http://example.com/some-report.pdf
   http://example.com/config.bak

2. Run:

   python3 kaplan.py

3. Check downloads/ and logs/ for results.

✅ Pro Tip: Pair this with Athena OS (our preferred red team distro, successor to BlackArch) for a hardened, opsec-ready environment.

🔐 OPSEC Notes

• Always run inside a VM or isolated environment.
• Ensure Tor is properly configured—no leaks!
• Consider delaying requests (time.sleep) in sequential mode to mimic human behavior.
• Never download directly onto your host machine—use encrypted, disposable storage.
