# How it works in practice

### Example of detected incident

When someone tries to inject malicious code into your payment page, Firstoken Monitor will detect the violation and you'll receive a report like this:

```json
{
  "referrer": "https://your-store.com/",
  "blocked-uri": "inline",
  "disposition": "enforce",
  "line-number": 15,
  "source-file": "https://your-store.com/checkout/payment",
  "status-code": 200,
  "document-uri": "https://your-store.com/checkout/payment",
  "script-sample": "",
  "original-policy": "default-src 'self'; style-src 'self'; img-src 'self'; font-src 'self'; connect-src 'self'; frame-ancestors 'self'; frame-src 'self'; child-src 'self'; worker-src 'none'; report-uri https://monitor.firstoken.co/v1/pages/E8178B09AF?t=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "violated-directive": "script-src-elem",
  "effective-directive": "script-src-elem"
}
```

**What does this report mean?**

* An unauthorized inline script attempted to execute on line 15
* The CSP successfully blocked the execution (`disposition: enforce`)
* The incident was automatically reported to Firstoken Monitor
* Your team received an immediate email alert

#### Types of attacks we detect

Firstoken Monitor's advanced analysis engine can identify and classify multiple types of security threats:

**High Priority Violations:**

1. **Nonce/Hash Violations**: Compromised security tokens or integrity checks.
2. **XSS Script Injection**: External malicious JavaScript injection.
3. **XSS Inline Script Injection**: Unauthorized inline script execution.

**Code Injection Attacks:**&#x20;

1. **Not permitted use of Eval()**: Dangerous eval() function usage.
2. **XSS Data Injection**: Data-based cross-site scripting attempts.
3. **Iframe Injection**: Malicious iframe embedding.
4. **Style Injection**: CSS-based attacks.
5. **Inline Style Injection**: Unauthorized inline styling.
6. **Malicious Worker**: Web worker exploitation.

**Advanced Threats:**

1. **Data Exfiltration**: Unauthorized data transmission attempts
2. **Clickjacking**: UI redressing attacks
3. **Not allowed Image**: Suspicious image loading from unauthorized sources

Each detected violation is automatically classified, prioritized, and reported with detailed context to help your security team respond quickly and effectively.
