A Pentester Took Apart a Website’s Code to Prove It Was Totally Pointless
SMRTR summary
A casino website used server-side signature verification to prevent unauthorized access. The author reverse-engineered the HMAC SHA256 signature algorithm with its static secret key. They created a Burp Suite extension to automatically generate valid signatures for any request, bypassing the security measure. The extension handles dynamic parameters, CSRF tokens, and user IDs across different casino games and functions. This shows how client-side security can be circumvented through analysis and custom tools.
