Using Chrome Developer Tools to hack your way into concerts

Talkat JSConf AU 2018 · on Tuesday, 2018-04-10· [security]

Shows concrete steps using Chrome Developer Tools: use XHR breakpoints, filter network by domain and type, inspect request/response and stack traces in Sources, and copy as cURL to replay requests. Recreates a ticket site locally, finds a rotating ID token, discovers the needed sequence (start then count), writes a Python script to automate the start+count flow and gets hundreds of views locally. Also demonstrates replay XHR and suggests mitigations like CAPTCHA, DOM randomization, and behavioral timing checks.
