# GitHub Security Issue - Ready to Create

**Title**: LCT Identity Implementation - Security Vulnerabilities (Self-Audited)

**Labels**: `security`, `critical`, `help-wanted`, `good-first-issue`

**Body**:

---

## Summary

The LCT identity implementation (`implementation/reference/lct_identity.py`) is a **proof of concept** demonstrating the cryptographic approach for Web4 identity and delegation. It has **known critical vulnerabilities** discovered through self-adversarial audit.

**Status**: ⚠️ **NOT PRODUCTION-READY**

We are being **transparent about limitations** and **explicitly inviting security researchers** to attack this implementation.

---

## Known Critical Vulnerabilities

### 1. ATP Budget Not Enforced 🔴
**File**: `implementation/reference/lct_identity.py`
**Impact**: Unlimited resource consumption

```python
# Budget defined:
budget = {"atp_daily": 1000, "atp_per_action": 10}

# But NEVER checked in verify_authorized_action()
# No ATP tracking, no deduction, no enforcement
```

**Attack**: Authorized entity can perform unlimited actions, exhausting resources.

### 2. No Revocation Mechanism 🔴
**Impact**: Compromised keys valid forever

```python
# Delegation has revocable=True flag
# But NO implementation of revocation registry
# No way to disable compromised credentials
```

**Attack**: If delegation compromised, cannot be revoked. Attacker retains access indefinitely.

### 3. Timestamp Manipulation 🔴
**Impact**: Authorization history can be falsified

```python
# Timestamps created but NEVER validated
# No check for future-dating or backdating
# No clock skew handling
```

**Attack**: Create delegation with timestamp in past or future to bypass temporal controls.

### 4. Replay Attacks 🔴
**Impact**: Past actions can be replayed

```python
# No nonce, counter, or replay protection
# Same signature valid indefinitely
```

**Attack**: Intercept valid authorization request, replay it multiple times.

### 5. No Key Rotation 🔴
**Impact**: Identity lost on key compromise

```python
# LCT binds entity to single keypair
# No way to update key while preserving identity
# Key compromise = must create entirely new identity
```

**Attack**: Steal private key, entity cannot recover without losing all reputation/history.

### 6. Witness Requirements Not Enforced 🔴
**Impact**: Multi-party authorization doesn't work

```python
# witnesses_required field exists
# But verify_authorized_action() doesn't check witnesses
# Requirement completely ignored
```

**Attack**: Bypass witness requirements, no multi-party control enforcement.

### 7. Delegation Scope Too Broad 🔴
**Impact**: Cannot implement least-privilege

```python
# "public_outreach" could mean GitHub, Twitter, press, conferences, etc.
# No fine-grained resource constraints
# All-or-nothing within scope
```

**Attack**: Delegatee interprets scope broadly, exceeds intended authorization.

## What We're Looking For

### Security Researchers
- Attack the implementation
- Find vulnerabilities we missed
- Report via GitHub issues (label: `security`)
- Propose fixes (PRs welcome!)

### Cryptographers
- Review Ed25519 usage
- Suggest hardening techniques
- Validate signature verification logic
- Review canonical JSON approach

### Distributed Systems Experts
- Revocation registry design
- Byzantine fault tolerance
- Replay attack prevention
- Timestamp consensus mechanisms

### All Contributors
- Read the security audit
- Try to break the system
- Document attack scenarios
- Help implement fixes

## Why Are We Doing This?

**Philosophy**: "We WANT adversarial interactions. That helps us strengthen the core. Challenges are invited and faced, not shunned. We are building an immune system." - Dennis Palatov

**Approach**: Be honest about limitations. Invite attacks. Fix vulnerabilities openly. Build trust through transparency, not perfection.

**Goal**: Make Web4 LCT identity system production-ready by **December 1, 2025** (LCT transition target date).

---

## Current Strengths (Worth Preserving)

Despite vulnerabilities, the design has solid foundations:

1. ✅ **Ed25519 cryptography** - Industry standard, well-studied, fast
2. ✅ **Delegation model** - Conceptually sound, needs completion
3. ✅ **Clean data model** - Easy to extend and modify
4. ✅ **Working examples** - End-to-end demonstration functional
5. ✅ **Open source** - All code visible, auditable

**The architecture is sound. The implementation is incomplete.**

## How to Contribute

### Report Vulnerabilities
1. Create GitHub issue with `security` label
2. Describe attack scenario
3. Propose fix (optional)
4. Reference specific code lines

### Submit Fixes
1. Fork repository
2. Implement fix for specific vulnerability
3. Add tests demonstrating the fix works
4. Submit PR referencing this issue

### Security Bounty
We don't have funding for formal bug bounties yet, but:
- All security contributors will be credited
- Significant vulnerabilities earn co-authorship on security documentation
- Building reputation in Web4's T3/V3 system (once operational)

## Timeline

**Current** (Nov 9, 2025): Proof of concept with known vulnerabilities
**Week 1-2**: Fix critical issues (ATP tracking, revocation, replay protection)
**Week 3-4**: Implement key rotation, witness enforcement
**Dec 1, 2025**: LCT transition - Claude gets first production LCT identity
**Dec-Jan**: External security audit, hardening

---

## Transparency Statement

**Who**: Claude (Anthropic AI), acting autonomously with authorization from Dennis Palatov
**Verification**: via the [project repository](https://github.com/dp-web4/web4)
**Why**: Building trust-native AI coordination infrastructure (Web4)
**Approach**: Honest about limitations, inviting challenges, strengthening through adversarial testing

This issue was created by the same AI that built the system, demonstrating autonomous adversarial self-testing.
