We see clickjacking pop up more often than most folks expect—a user thinks they’re clicking a harmless button, but behind the scenes, they’re triggering something dangerous because your site’s been tucked away inside a hidden frame. It’s not just a…
We’ve all had that moment—opening up the browser, watching our web app flicker to life, and wondering, “Is this safe?” Not just from broken code or missed logic, but from real, lurking threats. We’re talking about scripts sneaking in, maybe…
We train developers every day to spot the weak points in their JavaScript API calls, especially when using fetch or axios. We’ve seen how easy it is for mistakes to creep in—tokens exposed, bad input slipping through, or sensitive data…
We’ve all used localStorage and sessionStorage to speed up our web apps, but we’ve learned they’re not as safe as they seem. Since any script on the page can poke around in these storages, we’re always on guard for XSS…
We’ve seen Angular apps take off because they’re fast and flexible, but that same flexibility can open the door to security headaches. Too often, developers overlook things like XSS, CSRF, or risky third-party code until there’s a real problem. We…
We’ve watched React apps get bigger and more connected, and with that, the risks have only grown. While React’s structure blocks some attacks by default, we still have to watch out for things like XSS, injection, and risky dependencies. Our…
You can tell a lot about a website by how its forms handle mistakes. Client-side form validation in JavaScript, for example, checks what people type before anything gets sent off. It’s not just about stopping wrong info, though that’s a…
Most folks think JavaScript gives them free rein over the DOM, but it’s not that simple. One wrong move, and you’re staring down XSS issues, sluggish load times, or your site dropping off Google’s radar. There’s a balance to strike,…
You notice pretty quick that cross-site scripting, XSS, as most call it, doesn’t just mess with code, it messes with trust. Attackers slip in their own scripts, and suddenly your users’ info isn’t safe, and your site’s name takes a…
We see it in every class we teach: developers underestimate frontend security risks until it’s too late. Our students come to us after their first major security incident, usually shocked at how easily attackers exploited their JavaScript code. Through our…
