A GitHub repository set to public for 30 minutes, a Pastebin snippet, a leaked build artifact — any of these expose credentials that may be valid for years. Why It Happens The path to hardcoded credentials usually looks like one of these: "It's just for local dev" — developers add test credentials that survive to production Configuration complexity — environment variable setup is tedious; hardcoding is faster Not realizing it's a secret — internal API keys treated…
