ClickFix: When Attackers Trick You Into Infecting Your Own Device

ClickFix is a social engineering scam that tricks users into running malicious commands on their own computers. Instead of breaking into a system directly, Users may be instructed to open Run, PowerShell, Command Prompt, or Terminal, paste a command, and press Enter. While these steps may seem harmless, the command can download malware, steal sensitive information, or give attackers access to the device.

Why This Matters

ClickFix attacks are effective because they target people, not technology. By convincing users to perform the action themselves, attackers can bypass traditional security measures and gain access to valuable data, accounts, and systems. A single click can lead to credential theft, malware infections, or unauthorized access.

What to Watch For

Be cautious if a website or pop-up asks you to:

  • Verify you're human by following unusual steps
  • Open Run, PowerShell, Command Prompt, or Terminal
  • Copy and paste commands into your computer
  • Fix a browser, document, or security issue by running a command
  • Complete unexpected troubleshooting instructions

How to Stay Safe

 Think before you click and never run commands that you do not understand or not initiate yourself. 

 Be cautious of unexpected error messages, security alerts, or CAPTCHA prompts that ask you to take additional steps.

Reporting Suspicious Activity

If you notice a website asks you to copy, paste, and run a command, stop and verify before proceeding, and report it immediately to UTMB Information Security at cirt@utmb.edu.
