# Performing Graphql Security Assessment

## Overview

Cybersecurity skill for performing graphql security assessment. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing graphql security assessment"
- "Assessing GraphQL API endpoints for introspection leaks, injection attacks, auth"


- During authorized penetration tests when the target application uses a GraphQL API
- When assessing single-page applications (React, Vue, Angular) that communicate via GraphQL
- For evaluating mobile app backends that expose GraphQL endpoints
- When testing microservice architectures with a GraphQL gateway or federation
- During bug bounty programs targeting GraphQL-based APIs


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- **Authorization**: Written penetration testing agreement for the target
- **Burp Suite Professional**: With InQL extension for GraphQL scanning
- **GraphQL Voyager**: Schema visualization tool
- **InQL Scanner**: Burp extension for GraphQL introspection and query generation
- **Altair GraphQL Client**: Desktop GraphQL client for interactive testing
- **clairvoyance**: GraphQL schema enumeration when introspection is disabled
- **curl**: For manual GraphQL query submission

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Plan Operations** — Define objectives, scope, and success criteria for graphql security assessment operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for graphql security assessment.
3. **Execute Core Workflow** — Perform the graphql security assessment operations following established procedures.
4. **Validate Results** — Verify that results meet quality standards and objectives.
5. **Report Findings** — Document results, observations, and recommendations.
6. **Follow Up** — Track remediation actions and verify fixes where applicable.

## Tools

- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All graphql security assessment procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
