Security Usernames

Curated username lists pulled from SecLists for authorized security testing. You get the essentials: common usernames, default credentials, and name lists without downloading the full 4.5GB SecLists repo. Useful for pentesting engagements, bug bounties, or CTF challenges where you need to enumerate users or test default creds. The skill includes the top shortlist, CIRT default usernames, and common first/last names. Standard disclaimer applies: this is strictly for authorized testing with permission. If you're doing regular security work and don't want to manage the full SecLists collection, this gives you the username enumeration basics in a ready-to-use format.
