Oh For Fuck’s Sake, Now They’re Using React for Phishing?

Just when I thought the internet couldn’t get any more tedious, some absolute shitstain of a developer decided that vanilla HTML phishing pages weren’t “scalable” enough, so they’ve started building credential harvesting sites using React and exfiltrating stolen data through EmailJS. Christ on a fucking bicycle.

You read that right. These bellends are using a legitimate email delivery service—EmailJS—to ship your precious login credentials straight to their burner Gmail accounts. Because why bother setting up a sketchy C2 server in some Eastern European backwater when you can just npm install your way to identity theft? It’s “serverless” architecture, except instead of hosting cat photos, it’s hosting your fucking bank details.

The worst part? This shit actually works better than traditional phishing. EmailJS is legitimate infrastructure, you see. It’s not some freshly-registered domain with a reputation score lower than my patience for users who “just clicked the link.” It blends right into the noise. Your fancy Next-Gen AI-powered SOAR platform won’t flag a call to api.emailjs.com because Karen from Marketing uses it to send contact form notifications about her essential oils side-hustle.

And of course, they’re using React because why make a simple HTML form when you can pull down 47MB of node_modules, three different state management libraries, and a partridge in a pear tree? These phishing pages look polished. They’ve got animations. They’ve got Material UI components. They’ve probably got a fucking dark mode toggle. Meanwhile, your average user is dribbling over how professional it looks while happily typing their password into a component rendered by some twelve-year-old scammer in his mum’s basement.

The mitigation? Block EmailJS domains if you don’t need them. But good luck explaining to the CTO why his “innovative” marketing landing page stopped working. He’ll be in your office whining about “business critical email capture” while some Russian teenager is logging into his Salesforce instance using the credentials that just got exfiltrated through the same fucking API.

Anecdote time: Reminds me of the time some bright spark in Accounting decided to “optimize” the password reset process by storing credentials in Google Sheets via a client-side script. When I explained that this was about as secure as writing passwords on a toilet wall in Sharpie, he said “but it’s in the cloud.” I spent the next three hours explaining why “cloud” doesn’t mean “magic security dust.” Then I accidentally-on-purpose spilled coffee on his laptop. He didn’t learn, but my blood pressure improved.
