A 100-million-entry wordlist is useless if it takes weeks to process. Optimization is key.
| Pattern Type | Example | Prevalence |
|--------------|---------|-------------|
| First name + year | maria1978 | Very High |
| Football club + jersey number | flamengo10 | High |
| City name + birth date | riodejaneiro1985 | Medium |
| Simple dictionary word | senha, amor, brasil | Medium |
| Keyboard walking (PT layout) | qwerty123, aç (rare) | Low-Medium |
| Phone number fragments | 912345678 | Low | portuguese password wordlist work
Notable absence: English words like password appear less often; instead senha or acesso is used. A 100-million-entry wordlist is useless if it takes
john --wordlist=portuguese_wordlist.txt --rules=portuguese --format=NT hashes.txt
English-based wordlists (like rockyou.txt) are a great start, but they miss common Portuguese patterns: john --wordlist=portuguese_wordlist
awk 'length($0) >= 6 && length($0) <= 12' clean_wordlist.txt > filtered_length.txt
Imagine you are auditing a Portuguese bank. The base English wordlist finds only 5% of passwords. Here is how your portuguese password wordlist work pays off:
This wordlist was compiled exclusively for authorized security testing, educational research, and password strength auditing. Any use against systems without explicit permission is illegal under laws such as Brazil’s Marco Civil da Internet and Portugal’s Lei do Cibercrime.
Use pcfg (Probabilistic Context-Free Grammar) training on a Portuguese password dump. Tools like john's --make-charset can create a highly efficient character set.
