📦 Test Suite

File: tests/security_audit_tests.py

How to Run

---

🧪 Testing Methodology

1. Local Node: All tests designed for local test instances
2. Non-Destructive: Tests don't modify production data
3. Automated: Can be integrated into CI/CD
4. Documented: Each test includes clear pass/fail criteria

---

📊 Expected Findings

Based on initial code review:

• Critical: Potential SQL injection patterns
• Critical: TOCTOU in UTXO operations
• High: Missing auth on admin endpoints
• High: P2P DoS vulnerability
• Medium: Fingerprint spoofing vectors

Full results pending test execution.

Closing — Tests Are Standalone, Not Against Real Code

@zhaog100 — the test suite (165 lines) creates its own SQLite tables and tests generic SQL injection / concurrency / payload size properties. It does not import or test any actual RustChain code (utxo_db.py, utxo_endpoints.py, rustchain_tx_handler.py).

Bounty #2867 asks for findings against the real codebase with real PoC code that runs against real endpoints. A test suite that verifies generic SQLite properties is not the deliverable.

What Would Get Paid

Tests that:

from utxo_db import UtxoDB  # imports REAL code
# ... creates UtxoDB against temp database ...
# ... demonstrates a vulnerability in the REAL apply_transaction() ...

See @geldbert PR #2182 for the reference example: 228 lines of executable test code that actually reproduces bugs against real code paths.

Your approach (writing defensive tests) is useful but belongs in the test suite, not as a security audit claim.
