Avast blog: Understanding and preventing Cross-Site Scripting attacks

You wouldn’t think an attack method that was first found more than 20 years ago would be at the top of anyone’s list of popular current attacks. But that is the case for Cross-Site Scripting (XSS), a method that was first discovered by Microsoft engineers at the turn of the century. Avast’s XSS explainer webpage goes into more detail about the different attack types and some of the more notable attacks and victims down through the years. Top marks were issued by MITRE’s Common Weakness Enumeration group, which also listed 24 other dangerous software weaknesses.

I describe what all is involved with XSS attacks and some of the more notable ones of recent memory, along with how you can prevent them, in my blog post for Avast here.
