About SecLists

SecLists is a comprehensive collection of multiple types of lists used during security assessments, curated and maintained by security professionals. It includes usernames, passwords, URLs, sensitive data patterns, fuzzing payloads, web shells, and many other list types. The goal is to enable a security tester to pull this repository onto a new testing box and have access to every type of list that may be needed. The repository also contains wordlist generators and mutators in the .bin directory, and includes an Ai/LLM_Testing folder for testing language models. It is open source under the MIT license and can be installed via zip download, git clone, or package managers on Kali Linux and BlackArch.
