AlterX Subdomain Wordlist Generator Cheat Sheet

Überblick

AlterX ist ein schneller und anpassbarer Subdomain-Wordlist-Generator, entwickelt von Project Discovery. Er verwendet Muster und domänenspezifische Sprache (DSL), um Permutationen und Alterationen von Subdomains zu generieren, was ihn zu einem leistungsstarken Werkzeug für aktive Subdomain-Enumeration macht. AlterX passt in die Pipeline der aktiven Subdomain-Enumeration und ergänzt passive Subdomain-Erkennungstools wie Subfinder.

Was AlterX von anderen Wordlist-Generatoren unterscheidet, ist sein musterbasierter Ansatz und seine Fähigkeit, zielgerichtete, kontextbewusste Wordlists zu generieren. Anstatt generische Wordlists zu verwenden, kann AlterX Permutationen basierend auf bekannten Subdomains erstellen und erhöht damit die Chancen, verwandte Subdomains bei Sicherheitsbewertungen und Bug-Bounty-Jagden zu entdecken.

AlterX ist darauf ausgelegt, in Kombination mit Tools wie ShuffleDNS oder anderen DNS-Brute-Force-Tools verwendet zu werden, um neue Subdomains zu entdecken, die möglicherweise nicht durch passive Enumerationsmethoden gefunden werden. Seine anpassbaren Muster und der effiziente Generierungsalgorithmus machen ihn zu einem unverzichtbaren Werkzeug für umfassende Subdomain-Enumeration.

Basic Usage

Generating Wordlists

# Generate wordlist using default patterns
alterx -l subdomains.txt

# Generate wordlist with specific pattern
alterx -l subdomains.txt -p "\\\\{\\\\{word\\\\}\\\\}-dev"

# Generate wordlist from a single domain
alterx -d example.com -p "\\\\{\\\\{word\\\\}\\\\}-\\\\{\\\\{number\\\\}\\\\}"

# Generate wordlist from multiple domains
alterx -d example.com,hackerone.com -p "\\\\{\\\\{word\\\\}\\\\}-\\\\{\\\\{number\\\\}\\\\}"

Output Options

# Save results to a file
alterx -l subdomains.txt -o wordlist.txt

# Output in JSON format
alterx -l subdomains.txt -json -o wordlist.json

# Silent mode (only wordlist entries)
alterx -l subdomains.txt -silent

## Performance Optimization

### Concurrency and Rate Limiting

```bash
# Parallelität festlegen (Standard: 10)
alterx -l subdomains.txt -c 20

# Ratenlimit festlegen
alterx -l subdomains.txt -rate-limit 100

Optimization for Large Inputs

# Stream-Modus für große Eingaben verwenden
alterx -l large-subdomains.txt -stream

# Maximale Einträge begrenzen
alterx -l subdomains.txt -max-entries 1000

Troubleshooting

Common Issues

1. Memory Issues

   # Stream-Modus für große Eingaben verwenden
   alterx -l large-subdomains.txt -stream
   
   # Maximale Einträge begrenzen
   alterx -l subdomains.txt -max-entries 1000

2. **Pattern Issues**
   ```bash
   # Muster-Syntax überprüfen
   alterx -l subdomains.txt -p "\{\{word\}\}-dev" -debug

   # Einfache Muster zuerst verwenden
   alterx -l subdomains.txt -p "\{\{word\}\}"

3. No Output

   # Eingabedatei überprüfen
   cat subdomains.txt
   
   # Ausführlichen Modus verwenden
   alterx -l subdomains.txt -v

4. **Duplicate Entries**
   ```bash
   # Duplikate entfernen
   alterx -l subdomains.txt -silent|sort -u
