Cyber Mornings Daily - October 7th, 2026

So let's start at the perimeter, right? The web browser.

Yep.

This is where attackers are weaponizing the very tools meant to prove we are human.

We're looking at September 2026 findings from CERT-UA regarding a threat cluster dubbed UAC-0277.

That's right.

They compromised over 100 websites to deliver an information-stealing malware called LUNEX Stealer, sometimes referred to as Psychedelic Stealer.

Right, Psychedelic Stealer.

Okay, let's unpack this.

When you visit one of these compromised sites, you don't get the normal web page you asked for.

You get a forged CloudFlare verification page.

And it looks identical to the standard check, right? The one asking you to confirm you're a human before proceeding?

Exactly identical.

And, I mean, think about it.

We have all been completely conditioned by the modern web to just click whatever captcha or verification box pops up, you know, just to get to our content.

Yeah, it's just muscle memory at this point.

Exactly.

The friction is so common that it just breeds blind trust.

But instead of a simple click, this fake page prompts the user to execute a command.

This is known as the click fix technique.

Right.

The user thinks they are proving they are human, but executing that command actually reaches out to a remote server to download and install a malicious MSI package.

It's so sneaky.

It really is.

But the way they hide that backend infrastructure is what really caught my eye here.

They use a technique called ether hiding.
