Keynote address: Inside Cloudbleed

Wednesday 4 October 10:50 - 11:30, All rooms

John Graham-Cumming (Cloudflare)

In February 2017, Cloudflare was revealed to have been leaking private information including HTTP headers, cookies and POST data in malformed web pages. Some of this data had been cached by search engines. In this talk, Cloudflare's CTO, John Graham-Cumming, will look at the bug itself, the cleanup, its impact and how Cloudflare went about 'Cloud Hardening' its service after Cloudbleed.
