Detection & Classification +When a Shannon agent hits a dead-end (e.g., gets blocked by a WAF), it emits an `ObstacleEvent` containing: +- Terminal output (error messages, response body) +- Target URL and parameters +- Attempt history +- Engagement context + +### Phase 2: Pattern Matching +PIVOT matches the obstacle against 9+ hand-authored signatures: + +| Pattern ID | Matches | Classification | Confidence | +|------------|---------|----------------|------------| +| `WAF_GENERIC_BLOCK` | "403 Forbidden", "Access Denied", "Request blocked" | `WAF_BLOCK` | 0.9 | +| `SQL_ERROR_MYSQL` | "You have an error in your SQL syntax", "mysql_fetch" | `SQL_INJECTION_SURFACE` | 0.95 | +| `CHAR_BLACKLIST` | "invalid character", "character not allowed" | `CHARACTER_FILTER` | 0.85 | +| `SSTI_ERROR` | "TemplateSyntaxError", "jinja2.exceptions" | `TEMPLATE_INJECTION_SURFACE` | 0.9 | +| `RATE_LIMIT` | "429 Too Many Requests", "rate limit exceeded" | `RATE_LIMIT` | 0.95 | +| `AMBIGUOUS_500` | "500 Internal Server Error" | `UNKNOWN` | 0.4 | +| `EMPTY_RESPONSE` | (empty response) | `TIMEOUT_OR_DROP` | 0.3 | + +### Phase 3: Intelligent Routing +Based on pattern confidence and historical weights, PIVOT selects a lane: + +```typescript +if (top_match.confidence * weight > 0.75) โ†’ deterministic +if (top_match.confidence * weight < 0.40) โ†’ freestyle +if (between) โ†’ hybrid +if (no_matches) โ†’ freestyle with human_review_flag +``` + +### Phase 4: Mutation Execution + +#### Deterministic Lane (Rule-Based) +Applies mutation families in priority order: + +1. **Encoding Family** (13+ variants) + - URL single/double encoding + - HTML entity encoding (named, decimal, hex, mixed) + - Unicode escapes and fullwidth characters + - JSFuck transpilation + - Base64 injection wrapping + - Hex encoding + - UTF-7 encoding + - Null byte injection + - Overlong UTF-8 sequences + +2. **Structural Family** (8+ variants) + - Case variation (upper, lower, alternating, random) + - Whitespace injection (tabs, newlines, zero-width spaces) + - Comment injection (SQL, HTML, JS, CSS) + - Parameter pollution (duplicate params, array notation) + - HTTP verb tampering + - Content-type switching + - Chunked encoding + - Host header manipulation + +3. **Timing Family** (4 variants) + - Rate variation + - Concurrent delivery + - Delayed retry + - Race condition templates + +4. **Protocol Family** (4 variants) + - HTTP version switching + - Header injection + - Chunked encoding + - Host manipulation + +#### Freestyle Lane (LLM-Assisted) +When deterministic approaches fail, PIVOT uses constrained LLM prompts: + +```json +{ + "strategy": "unicode_fullwidth_bypass", + "mutation_family": "encoding", + "payload_template": "๏ฝ“๏ฝƒ๏ฝ’๏ฝ‰๏ฝ๏ฝ”>alert(1)", + "rationale": "Fullwidth Unicode bypasses ASCII keyword filters" +} +``` + +### Phase 5: Scoring & Validation +Each mutation attempt is scored using 7 signal rules: + +| Signal | Weight | Type | Threshold | +|--------|--------|------|-----------| +| `status_changed` | 2.0 | binary | - | +| `error_class_changed` | 1.5 | binary | - | +| `body_contains_target` | 5.0 | binary | - | +| `timing_delta` | 0.8 | threshold | 2.5ฯƒ | +| `payload_reflected` | 1.2 | binary | - | +| `body_length_delta` | 0.6 | threshold | 15% | +| `new_headers_present` | 0.9 | binary | - | + +**Scoring thresholds:** +- `progress_threshold`: 1.5 (making progress) +- `exploit_confirm_threshold`: 5.0 (confirmed exploit) +- `abandon_threshold`: 8 attempts without progress + +### Phase 6: Post-Engagement Learning +After each engagement, PIVOT: +1. Reviews routing decisions +2. Identifies misrouted obstacles +3. Proposes weight adjustments +4. Learns new patterns from anomalies +5.
