Security Patterns

A curated collection of regex patterns and test data for finding sensitive information like API keys, credit cards, SSNs, and IP addresses in codebases or logs. Pulled from the SecLists Pattern-Matching directory, so you get battle-tested patterns rather than rolling your own. Honestly most useful for security audits where you need to scan for accidental data leaks, or building validators for PII detection tooling. The usual disclaimer applies: this is for authorized testing only, bug bounties, CTFs, or your own systems. If you need the full SecLists arsenal beyond pattern matching, the complete repo has 6,000+ files covering fuzzing, payloads, and web shells.
