Hackers Are Blowing Past Your MFA…Here’s How to Stop Them

Let’s clear the air:

Hackers don’t need your password anymore.
They don’t even need your MFA code.
They just need you to log in once and then they’ll ride your session like a stolen car.

That’s where we are. And it’s happening more than most people realize.

Meet the New Threat: EvilGinx 3

If you haven’t heard of EvilGinx 3, it’s not some made-up Hollywood thing. It’s a real tool used in red team exercises and, unfortunately, by real-world attackers.

Here’s the short version of how it works:

1. You get a phishing email. You click the link.
2. It takes you to a perfect clone of a real login page — like Microsoft 365.
3. You enter your username, password, and MFA code.
4. The attacker captures all of it, including your session token.
5. You get logged in. Everything looks normal.
6. Meanwhile, the attacker uses the token to log in as you, with no prompt, no MFA challenge, and no detection.

That token? It’s like a backstage pass. As long as it’s valid, they can move freely through your systems.

But MFA Was Supposed to Fix This… Right?

Yes… but.

We built MFA to block brute-force attacks and stolen credentials.

But today’s attackers aren’t climbing the wall. They’re tricking your users into opening the gate.

We see this every week. Real cases. Real damage.

Let’s Get Real. What’s at Risk?

• Cloud storage gets emptied
• Financials get rerouted
• Email becomes a launchpad for phishing others
• Client data gets exposed
• Trust gets destroyed

Even worse? Many of these attacks happen inside MSP environments, where one admin account can compromise dozens of clients downstream.

This isn’t just a breach. It’s a blast radius.

Here’s What Actually Works

Whether you’re an MSP, IT leader, or business owner, here’s what you need in place:

• Hardware-Based Authentication (WebAuthn, YubiKey)
• Continuous Monitoring
• Short Session Tokens
• Managed Detection & Response (MDR)

One Last Thought: It’s Time to Stop Outsourcing Responsibility

You can’t outsource trust.
You can’t solve this with tools alone.
And you definitely can’t check a box labeled “MFA” and call it good.

As I wrote in VisibleOps Cybersecurity:

“Security without process is just expensive theater.”

MFA is a tool. Not a strategy.
It’s the people, process, and visibility behind it that make the difference.

Final Word

The attackers are already adapting. Are you?

It’s time to shift from checkbox compliance to real risk reduction.

You don’t need perfect security. But you do need a plan that evolves faster than the threat.

That starts with recognizing that MFA on its own is no longer the hero of the story.

Let’s get serious. Let’s get proactive.

Let’s get secure.
