Abstract:
Alert(1): it's everyone's favorite cross-site scripting (XSS) payload, but that doesn't mean you have to stop there. In this talk, we will explore the variety of exploits we can weaponize after we've gotten that alert box to pop. From session hijacking to crypto mining, there are a multitude of ways to exploit your victim with this decades-old class of vulnerability. It's sometimes hard to get buy-in to correct XSS vulnerabilities because an alert box isn't a compelling risk - this talk shows how to weaponize flaws once they're found.
For offensive security pros, you will walk away with a few new tricks to add to your engagements. People on the defensive side will learn signatures to detect and alert on. And for everyone else, come find out why XSS always finds its way to the top of web vulnerability top 10 lists.
