### 8 Specialized Agents
| Agent | Focus Area | OWASP Category |
|-------|------------|----------------|
| **XSS** | Cross-Site Scripting, DOM manipulation, script injection | A03:2021-Injection |
| **SQLi** | SQL Injection, database queries, ORM vulnerabilities | A03:2021-Injection |
| **Auth** | Authentication bypass, IDOR, sessions, JWT, OAuth | A01:2021-Broken Access Control |
| **API** | REST/GraphQL security, CORS, rate limiting, mass assignment | API Security Top 10 |
| **Crypto** | TLS/SSL issues, weak ciphers, certificate problems | A02:2021-Cryptographic Failures |
| **Secrets** | API keys, tokens, hardcoded credentials, private keys | A02:2021-Cryptographic Failures |
| **Headers** | HTTP security headers, CSP, HSTS, cookie security | A05:2021-Security Misconfiguration |
| **General** | Fallback for unclassified findings, business logic | A05:2021-Security Misconfiguration |
### Routing Logic
Findings are automatically routed based on type:
| Finding Type | Primary Agent | Confidence |
|--------------|---------------|------------|
| `javascript` | Secrets (if contains keys) or XSS | 80-90% |
| `http` | Headers | 80% |
| `technology` | Crypto | 80% |
| `api` | API | 90% |
| `takeover` | Auth | 90% |
| `security_issue` | General | 80% |
### Sample Multi-Agent Output
```

- Part of 20 passive sources executed in parallel
**Integration:** Results merged into subdomain discovery (scanner.go lines 115-143)
---
### 6. Subdomain Permutation/Alteration
**Status:** IMPLEMENTED ✅
**Finding:** Intelligent pattern-based permutation generation with machine learning.
**Functions:**

**Finding:** Explicit HTTP/2 support enabled in client factory.
**File:** `/Users/lucalorenzi/CascadeProjects/windsurf-project-6/god-eye/internal/http/factory.go`
**Implementation (lines 54 & 73):**
```go
ForceAttemptHTTP2: true
```
**Details:**
- Both secure and insecure transports have HTTP/2 enabled
- Secure transport (TLS verification): line 54
- Insecure transport (for scanning): line 73
- TLS 1.2+ required for HTTP/2
- Go's net/http automatically handles HTTP/1.1 fallback
---
### 8. Proxy Support (SOCKS5, HTTP proxy, Tor)
**Status:** NOT IMPLEMENTED ❌
**Finding:** No proxy support in the codebase.
**Search Results:**
- Grep for "SOCKS|socks5|Tor|tor|proxy" found only validation references
- No dialer configuration for custom proxies
- HTTP transports use default Go net.Dialer (lines 42-45, 60-63 in factory.go)
**Why:** HTTP clients created without custom proxy dialing support
- Standard Go HTTP transport doesn't support SOCKS natively
- Would require `golang.org/x/net/proxy` package (not present in go.mod)
---
### 9. Input from File (Domain List)
**Status:** NOT IMPLEMENTED ❌
**Finding:** Only single domain mode supported.
**Evidence:**
- Config struct has single `Domain` field (config.go:9)
- Main CLI flag: `-d domain` (main.go:118)
- No batch processing or domain list input
- No `.GetDomainsFromFile()` or similar function
**Limitation:** Scanner processes one domain per invocation
---
### 10. Resume/Checkpoint Functionality
**Status:** NOT IMPLEMENTED ❌
**Finding:** No state persistence or resume capability.
**Search Results:**
- Grep for "resume|checkpoint|state.*save|state.*restore" found 0 matches in scanner/config
- No cache beyond passive source results and single-scan buffering
- Results are volatile (in-memory only)
**Cache Implementation:** `/Users/lucalorenzi/CascadeProjects/windsurf-project-6/god-eye/internal/cache/cache.go`
- Only provides in-memory caching during active scan
- Not persistent across invocations
---
### 11. Screenshot Capture
**Status:** NOT IMPLEMENTED ❌
**Finding:** No screenshot functionality.
**Search Results:**
- Grep for "screenshot|selenium|playwright|headless" found 0 matches
- No browser automation libraries in dependencies
- No image capture during HTTP probing
**Rationale:** Tool focuses on recon data, not visual analysis
---
### 12. HTML Report Output
**Status:** NOT IMPLEMENTED ❌ (but JSON structure supports it)
**Finding:** No HTML template generation implemented.
**Supported Output Formats (internal/output/print.go:105-144):**
- TXT format (default) - simple subdomain list
- JSON format - complete detailed structure
- CSV format - tabular data
**JSON Output Structure:** Comprehensive `/Users/lucalorenzi/CascadeProjects/windsurf-project-6/god-eye/internal/output/json.go`
- Includes ScanReport, ScanMeta, ScanStats, Findings by severity
- Could be used as basis for HTML generation (not implemented)
**CLI Support:**
- `-f json` or `--json` flag (main.go:123, 133)
- `-o output.json` for file output (main.go:122)
---
### 13. Scope Control (Whitelist/Blacklist)
**Status:** NOT IMPLEMENTED ❌
**Finding:** No scope filtering mechanism.
**Search Results:**
- Grep for "whitelist|blacklist|scope|include|exclude" in config returned 0 matches
- All discovered subdomains are included in results
- No filtering rules for subdomain exclusion
**Related Feature:** Only active/inactive filtering available
- `--active` flag (main.go:132) - shows only HTTP 2xx/3xx
- Not a true scope control mechanism
---
### 14. Rate Limiting Intelligence
**Status:** IMPLEMENTED ✅
**Finding:** Advanced adaptive rate limiting with multiple implementations.
### 14A. Adaptive Rate Limiter
**File:** `/Users/lucalorenzi/CascadeProjects/windsurf-project-6/god-eye/internal/ratelimit/ratelimit.go`
**Type:** `AdaptiveRateLimiter` (lines 10-28)
**Features:**
- Dynamic backoff on errors (2x multiplier)
- Enhanced backoff for rate-limit errors 429 (2x more aggressive)
- Recovery on success (0.9x multiplier)
- Configurable min/max delays
- Error tracking and statistics

### 14C. Stealth Module
**File:** `/Users/lucalorenzi/CascadeProjects/windsurf-project-6/god-eye/internal/stealth/stealth.go`
**Modes (lines 14-20):**
- Off - maximum speed
- Light - reduced concurrency, basic delays
- Moderate - random delays, UA rotation
- Aggressive - slow, distributed, evasive
- Paranoid - ultra slow, maximum evasion
**Rate Limiting Aspects:**
- Per-mode delay presets
- Per-host request limits

## Architecture Observations
### Strengths
1. **Concurrency Design**: Worker pools, semaphores, proper goroutine management
2. **Connection Pooling**: Reusable HTTP transports, connection pooling per host
3. **Error Handling**: Retry logic with exponential backoff
4. **Passive Sources**: 20 parallel sources with robust error handling
5. **Rate Limiting**: Multi-layer (adaptive + concurrency + stealth)
6. **Modularity**: Clean separation: dns/, http/, scanner/, security/, sources/, etc.
### Weaknesses
1. **No Persistence**: Results lost between invocations
2. **Single Domain**: Can't batch process domain lists
3. **No Proxy Support**: Limited in restricted networks
4. **No AXFR**: Important for zone enumeration
5. **No Scope Control**: All subdomains included equally
### Modern Go Practices
- Proper use of `sync.Mutex` and channels
- Context-based cancellation
- Interface-based design
- Dependency injection patterns
- Configuration objects over global state
---
## Conclusion
God's Eye is a **well-architected, feature-rich subdomain enumeration tool** with:
- **Strong core features** (passive + active + security checks)
- **Intelligent rate limiting** (adaptive + concurrency control)
- **Modern Go best practices** (concurrency, pooling, error handling)
- **AI integration** (Ollama-based analysis)
- **Production-ready quality** (caching, stealth, reporting)
**Missing features are primarily convenience features** (batch input, snapshots) and infrastructure features (proxy, AXFR), not core functionality.
**Recommended Priority for Enhancement:**
1. Batch domain input (enables bulk scanning)
2. Scope control (critical for large-scale assessment)
3. Checkpoint/resume (for long scans)
4. SOCKS proxy (for restricted networks)
5. HTML report generation (from existing JSON)
