OpenBullet uses its Wordlist tab to manage and generate datasets for testing login credentials. This feature allows users to import, create, and organize the data needed for automated web testing and credential stuffing simulations. Key Wordlist Features

Extract only unique emails from combos

cut -d':' -f1 combo.txt | sort -u

Disclaimer: The official OpenBullet GitHub explicitly warns users against targeting websites they do not own.

• Password lists often contain millions of leaked or commonly used passwords.
• Username lists include likely account names, email patterns, or harvested identifiers.
• Combo lists pair usernames and passwords (often from previous breaches).
• Custom lists can contain session tokens, API keys, or parameter values used to automate targeted testing.

Why Standard Wordlists Fail

If you take a generic rockyou.txt wordlist (which only contains passwords) and feed it into OpenBullet, it will fail. OpenBullet needs a pairing. Even if you are testing only usernames, you must format the file as username: (with an empty password slot).
