You cannot legally download the full RockYou2024 from public trackers in many jurisdictions. Instead, build your own "better" list by aggregating publicly available breach dumps (HaveIBeenPwned's Pwned Passwords, SecLists, etc.) and applying the steps above.
Recommended workbench:
Ethical alternative: Use rockyou.txt (original) + SecLists/Passwords/Common-Credentials/10-million-password-list-top-1000000.txt. Apply the same filtering and mutation steps. For 99% of penetration tests, you won't need the full 10 billion. rockyou2024txt better
The single biggest improvement over RockYou2024 is discarding low-probability passwords. Use the Zipf distribution property of human passwords: the top 1 million passwords cover ~30% of real users.
Keep only passwords that appear in at least 2 distinct breaches (using a reference like haveibeenpwned v3 API or Pwned Passwords downloadable hashes). This instantly cuts RockYou2024 from billions to <500 million lines.
Command example with pwned-passwords-util: Disclaimer: Only use these techniques on systems you
pwned-passwords-download -f sha1
pwned-passwords-filter -count 2 rockyou2024.txt > rockyou2024_better.txt
Remember: The goal of a password list is not to invade privacy but to strengthen defenses. Use these techniques to help organizations choose better passwords and implement multi-factor authentication.
Want to go further? In my next article, I’ll cover how to combine RockYou2024 mutations with Markov chain generators to crack even complex, random-looking passwords. Stay tuned.
Despite the "9.4 billion lines" claim, a significant portion of the list consists of: Ethical alternative: Use rockyou
A better wordlist would deduplicate intelligently—not just unique lines, but unique password strings. Many tools already remove exact duplicates, but RockYou2024 contains structural duplicates (e.g., "Password1!", "password1!", "Password1") that effectively waste cracking time.
