Date: Wednesday August 07, 2019
Time: 10:30 - 10:55
Location: South Pacific

It is the year 2019. Humanity has almost won its long-standing war against Single-Sign On (SSO) bugs. The last of them were discovered and eradicated some time ago and the world is now living in an era of prosperity while the Auth Federation enjoys peaceful CVE-free times. However, while things seem to be running smoothly, new bugs are brewing at the core of major implementation libraries. This is probably the last chance for the evil empire to launch a world scale attack against the Auth Federation.

In this talk, we will present two new techniques:
