Cookies has been a basic foundation for web development for decades. It is used widely by applications and security solutions, but unfortunately also by trackers threatening our privacy.
In 2020 Google changed the default SameSite behaviour for cookies to Lax and Safari enabled full 3rd party cookie blocking. These changes required updates to a vast range of sites. In 2022 Firefox introduced a unique concept of cookie buckets to improve privacy, while still trying to not break single sign on and other valid solutions.
Using cookies and making sure they work across different browsers is harder than ever. And there is more to come...
There's an even easier way to ensure your website was never vulnerable to CSRF or clickjacking: these are both instances of the Confused Deputy Problem. It turns out that when Norm Hardy first wrote about this problem in 1988, he also described the solution for it. If you've been building systems the way he described, you've looked on in bewilderment at the rest of the world as it grapples to plug holes in a legacy security model.
The alarm triggering at the 20 minutes was very ammusing
I thunk the cookie jar approach with http header that would whitelist origins where from the cookies are accepted, would be very robust and reliable solution.
Very nice talk.
So everyone wants to fix it so ads can still track us, but screw security 😅
