ATM Jackpot (DEF CON 18, 2010) – Barnaby Jack rolled a real ATM onstage and made it spew cash with a remote exploit. The demo coined the term “jackpotting” and forced ATM vendors to overhaul firmware security. #Defcon #Hackers

Ensure your JWTs are secure: enforce strict algorithms, employ robust keys, and review those claims. Explore more insights here: toxsec.com/p/hacking-jwts-a-… #CyberSecurity #ApplicationSecurity

Explore every parameter thoroughly. Go beyond just testing id=. Experiment with integer fuzzing, use negative values, encoded payloads, and delve into nested JSON keys. Even "read-only" parameters can hide IDOR or injection vulnerabilities. #CyberSecurity #PenTesting

Check old API versions. Developers rarely fully decommission /v1/ or /beta/ endpoints. Send OPTIONS/TRACE requests and diff responses to find legacy logic. #Bug Bounty

funny how every scope has at least one API nobody remembers deploying. #bugbounty

Review JavaScript for secrets. Run linkfinder or JSFScan to extract endpoints and API keys from front-end scripts. Many bounty-winning chains start with a forgotten token. #BugBounty

What’s the most surprising place you’ve discovered a hard-coded secret?
