SecretFinder Find Extract Hardcoded Secrets, API Keys, Toketns from JavaScript: SecretFinder is a powerful open-source security tool used to find, extract, and analyze hardcoded secrets, API keys, access tokens, and sensitive credentials directly from JavaScript files. In this video, you will learn how to use SecretFinder step by step to uncover exposed secrets hidden inside client-side JavaScript code — a common and critical security issue in modern web applications. JavaScript files often contain sensitive information such as API keys, OAuth tokens, AWS credentials, Firebase configs, payment gateway keys, and internal endpoints. Attackers and bug bounty hunters actively analyze JS files to discover misconfigurations and data exposure. SecretFinder automates this process using advanced regex-based pattern matching, making it a must-have tool for bug bounty hunting, web penetration testing, and client-side security audits. In this tutorial, we cover: #What SecretFinder is and how it works #Installing SecretFinder on Linux, macOS, and Windows #Scanning local JavaScript files for secrets #Extracting and scanning JavaScript files directly from URLs #Finding exposed API keys and tokens from live websites #Exporting results in CLI, HTML, and JSON formats #Reducing false positives and identifying real secrets #Practical bug bounty and real-world use cases SecretFinder is especially useful when combined with recon tools like gau, waybackurls, httpx, Subfinder, and secret scanning tools such as Mantra, TruffleHog, and Gitleaks. While backend repositories may be protected, client-side JavaScript is publicly accessible — making it a frequent source of high-impact vulnerabilities. #This video is ideal for: #Bug bounty hunters #Ethical hackers #Web penetration testers #DevSecOps engineers #Cybersecurity students Anyone interested in JavaScript security testing By the end of this video, you will be able to confidently use SecretFinder to identify leaked secrets in JavaScript, validate findings, and understand how attackers exploit exposed keys. You will also learn best practices for responsible disclosure and avoiding false positives during testing. If you are serious about client-side security, API key leak detection, and modern web application testing, this SecretFinder tutorial will give you practical skills you can apply immediately. #secretfinder #secretfindertool #javascriptsecurity #jssecurity #apikeyleak #apikeys #apitokens #hiddensecrets #hardcodedsecrets #bugbounty #bugbountytips #bugbountytools #ethicalhacking #websecurity #webpentesting #pentesting #clientsecurity #frontendsecurity #jsanalysis #javascriptpentesting #securitytesting #cybersecurity #infosec #recon #recontools #opensource #securitytools #leakedapikeys #tokendetection #oauth #awskeys #firebasekeys #paymentgateway #stripeapikey #googleapikey #githubsecrets #secretdetection #jsfiles #webhacking #hackingtutorial #pentestingtools #securityresearch #devsecops #automation #reconautomation #waybackurls #gau #httpx #subfinder #mantra #trufflehog #gitleaks #bugbountyindia #bugbountybangladesh #bugbountycommunity #learnhacking #cybersecuritytraining #infosectraining secretfinder, secretfinder tool, secretfinder tutorial, javascript secret finder, javascript security, js security, api key leak, api key detection, hidden api keys, hardcoded secrets, javascript api keys, find api keys in js, token detection, access token leak, oauth token, aws api key, firebase api key, google api key, stripe api key, payment gateway keys, leaked credentials, secret scanning tool, bug bounty, bug bounty tools, bug bounty hunting, bug bounty tutorial, ethical hacking, ethical hacker, web security, web pentesting, penetration testing, client side security, frontend security, javascript pentesting, js file analysis, recon tools, recon automation, gau tool, waybackurls, httpx tool, subfinder, mantra tool, trufflehog, gitleaks, secret detection, open source security tools, cybersecurity, infosec, infosec tools, security research, devsecops, hacking tutorial, web hacking, cyber security training, learn ethical hacking, bug bounty methodology, api security, exposed secrets, js secrets finder, web application security
