# Bypassing Authentication With Forced Browsing

## Overview

Cybersecurity skill for bypassing authentication with forced browsing. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "bypassing authentication with forced browsing"
- "Discovering and accessing unprotected pages, APIs, and administrative interfaces"


- During authorized penetration tests to discover hidden or unprotected administrative pages
- When testing whether authentication is consistently enforced across all application endpoints
- For identifying backup files, configuration files, and debug interfaces left exposed in production
- When assessing access control on API endpoints that should require authentication
- During security audits to validate that all sensitive resources enforce session validation


## 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 covering directory enumeration
- **ffuf**: Fast web fuzzer (`go install github.com/ffuf/ffuf/v2@latest`)
- **Gobuster**: Directory brute-force tool (`apt install gobuster`)
- **Burp Suite**: For intercepting and analyzing requests and responses
- **Wordlists**: SecLists collection (`git clone https://github.com/danielmiessler/SecLists.git`)
- **Target access**: Network connectivity and valid test credentials for authenticated comparison

## 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. **Define Objectives** — Clarify the goals and scope for authentication.
2. **Gather Resources** — Collect tools, data, and access needed for authentication.
3. **Execute Process** — Carry out authentication operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **forced browsing** — Primary tool for this skill
- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Prepare** — Gather requirements, verify prerequisites, set up environment
1. **Execute** — Run bypassing authentication with forced browsing workflow with configured parameters
1. **Verify** — Validate output meets requirements, document results

## Verification

- [ ] All authentication 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. |
