# Performing Wifi Password Cracking With Aircrack

## Overview

Cybersecurity skill for performing wifi password cracking with aircrack. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing wifi password cracking with aircrack"
- "Captures WPA/WPA2 handshakes and performs offline password cracking using aircra"


- Assessing the strength of WPA/WPA2/WPA3 passphrases during authorized wireless penetration tests
- Testing whether wireless networks are using weak or default passwords that can be cracked offline
- Capturing and analyzing 4-way handshakes to evaluate wireless authentication security
- Demonstrating the risks of WEP, weak WPA2 passphrases, and PMKID-based attacks to stakeholders
- Validating that enterprise wireless networks use 802.1X/EAP instead of pre-shared keys

**Do not use** against wireless networks without explicit written authorization, for disrupting wireless communications, or for capturing handshakes of networks you do not have permission to test.


## 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

- Written authorization specifying in-scope SSIDs and wireless networks
- Wireless adapter with monitor mode and packet injection support (Alfa AWUS036ACH, Alfa AWUS036ACM, or similar)
- Kali Linux with aircrack-ng suite, hashcat, and hcxtools installed
- Password wordlists (rockyou.txt, SecLists, or custom organization-specific lists)
- GPU-capable system for hashcat acceleration (optional but recommended for large wordlists)

## 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 wifi password cracking operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for wifi password cracking.
3. **Execute Core Workflow** — Use aircrack to perform wifi password cracking 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

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


## Process

1. **Design** — Define interface, identify patterns, plan implementation
1. **Implement** — Write code following existing conventions, add tests
1. **Verify** — Run tests, check integration, validate behavior

## Verification

- [ ] All wifi password cracking 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. |
