What does HackerNews think of SecLists?

SecLists is the security tester's companion. It's a collection of multiple types of lists used during security assessments, collected in one place. List types include usernames, passwords, URLs, sensitive data patterns, fuzzing payloads, web shells, and many more.

Language: PHP

This reminds me of [0] where they maintain composite lists of frequently used passwords. Also in the repo is probably my favorite pull request ever [1].

SecLists (https://github.com/danielmiessler/SecLists) contains a wealth of security-related lists of this sort, including a useful section containing the most common passwords.
This is really useful for security testing, where unexpected input could have security implications.

There is a similar project, which I think is better organized and has more lists to play with:

Another good list that incorporates FuzzDB: https://github.com/danielmiessler/SecLists

As other commenters noted, strings like DROP TABLES should be used with caution!
