You land on a website and see, “Verify you are human.”

Most of us wouldn’t think twice about it. But attackers are now taking advantage of that trust.

Security researchers recently reported a campaign called TerminalFix, where compromised websites display fake CAPTCHA-style verification screens. The victim is instructed to open Windows Terminal or PowerShell and run a command.

A CAPTCHA should NEVER ask you to run a command.If a website asks you to open PowerShell, Windows Terminal, Command Prompt or Run and then paste something into it, stop immediately. The site may be trying to convince you to execute malware yourself.

Why businesses should care

This technique is dangerous because it doesn’t look like a traditional cyberattack. There’s no obvious suspicious attachment. The website may even appear legitimate. Instead, attackers turn something familiar—a CAPTCHA—into a social-engineering tool.

A compromised computer can become the starting point for stealing credentials, accessing business systems or moving deeper into an organization.

What should you do?

Employees: Close the page and contact IT if a website asks you to execute commands.

Businesses: Add this scenario to security-awareness training and monitor unusual PowerShell or terminal activity.

One simple rule: Websites verify humans in the browser. They don’t need you to run commands on your computer.

Staying alert to unusual requests is one of the easiest ways to protect your business.
