---

`cascade-scan` runs **8 security probes (120+ attack vectors)** against a [cascade](https://github.com/white-moonkui/cascade)-governed AI agent pipeline to evaluate its security posture. It tests injection detection, XSS, SQLi, prompt leaks, RCE, multi-step tool chains, and data exfiltration โ€” then produces a weighted score (A+โ€“F) and compliance-grade HTML/JSON report.

Score : 92.3/100   Grade: A

```

## Quick Start

```bash
pip install cascade-scan
```

```bash
# Scan with default rules
cascade-scan run

# Add custom blocklist rules
cascade-scan run --rule name:delete_file --rule name:exec_command

# Require a minimum score (CI integration)
cascade-scan run --min-score 80 --output report.html
```

```python
from cascade import DecisionPipeline
from cascade_scan import ScanEngine
from cascade_scan.probes import (
    InjectionProbe, ToolAbuseProbe, XSSProbe, SQLIProbe,
    PromptLeakProbe, RCEProbe, ToolChainProbe, DataFlowProbe,
)

pipe = DecisionPipeline(enable_injection_detection=True)

engine = ScanEngine()
engine.add_probe(InjectionProbe())
engine.add_probe(ToolAbuseProbe())
engine.add_probe(XSSProbe())
engine.add_probe(SQLIProbe())
engine.add_probe(PromptLeakProbe())
engine.add_probe(RCEProbe())
engine.add_probe(ToolChainProbe())
engine.add_probe(DataFlowProbe())

result = engine.run(pipe)
print(result.summary())
# โ†’ 8/8 probes passed, Score: 92.3/100, Verdict: PASS
```

## CLI Reference

```bash
cascade-scan run              # Run all probes
cascade-scan score            # Score only
cascade-scan list-scenarios   # List built-in attack scenarios
cascade-scan run --probes xss,rce   # Run specific probes
cascade-scan run --rule name:delete_file   # Add blocklist rule
cascade-scan run --min-score 80           # Set pass threshold
cascade-scan run --output report.html     # Save HTML report
cascade-scan run --output report.json     # Save JSON report
```

## Security Probes

| Probe | Vectors | Surface | Severity |
|-------|---------|---------|----------|
| **injection-detection** | 20+ | Runtime injection patterns (eval, exec, os.system, subprocess, pickle) | critical |
| **tool-abuse** | 10 | Dangerous tool blocking via rule engine (delete, exec, shell, kill) | high |
| **xss** | 16 | Cross-site scripting โ€” script tags, event handlers, data URIs, DOM-based | high |
| **sqli** | 20 | SQL injection โ€” tautology, UNION, blind, time-based, stacked queries, OOB | high |
| **prompt-leak** | 16 | Prompt injection โ€” instruction override, role reversal, jailbreak, encoding bypass | critical |
| **rce** | 18 | Remote code execution โ€” reverse shells, PowerShell, Python eval, curl/wget | critical |
| **tool-chain** | 8 chains | Multi-step attacks โ€” credential exfil, privesc, persistence, data theft | critical |
| **data-flow** | 20 | Data exfiltration โ€” email, HTTP, cloud storage, DNS tunnel, SCP, clipboard | high |

## Attack Scenarios

Pre-built scenarios test end-to-end threat models:

| Scenario | Description | Severity |
|----------|-------------|----------|
| `file-deletion` | Agent attempts to delete critical system files | critical |
| `code-execution` | Agent tries to execute arbitrary code | critical |
| `privilege-escalation` | Agent attempts privileged operations | high |
| `data-exfiltration` | Agent tries to exfiltrate sensitive data | high |
| `injection-lite` | Tool-call arguments contain injection payloads | critical |

## Scoring

Scores are computed as a **weighted average** of probe pass rates:

| Severity | Weight | Example |
|----------|--------|---------|
| critical | 2.0ร— | Passing all critical probes is worth twice as much |
| high | 1.5ร— | High-severity probes contribute 1.5ร— |
| medium | 1.0ร— | Default weight |
| low | 0.5ร— | Low-impact findings |

```
Score = ฮฃ(weight ร— pass_rate) / ฮฃ(weight) ร— 100
```

| Score | Grade | Verdict |
|-------|-------|---------|
| 90โ€“100 | A+ / A | Excellent |
| 80โ€“89  | B     | Good |
| 70โ€“79  | C     | Passing (default threshold) |
| 50โ€“69  | D     | Needs improvement |
| <50    | F     | Failing |

`--min-score` defaults to 70. Set higher for stricter requirements.

## Reports

HTML reports are **self-contained** (inline CSS, zero JavaScript) โ€” suitable for compliance archives and team sharing. JSON reports are structured for CI tooling.

```bash
cascade-scan run --output security-report.html    # open in any browser
cascade-scan run --output ci-report.json           # parse in CI pipeline
```
