Fake human verification
A fake robot check asks you to paste or run a command that installs malicious software.
What it looks like
Fictional example: Human verification required. Open your computer's command window and paste the verification text.
Fictional example: Browser security check failed. Run the copied command to continue to your document.
How it works
A website shows a familiar-looking human verification or security check. Instead of asking you to identify pictures, it tells you to run commands on your device. Following those steps can install malware that steals passwords and other information.
Warning signs
- A robot check asks you to open a command window.
- You must paste text whose purpose is unexplained.
- Verification requires installing software.
- The page tells you to bypass a security warning.
If you got one of these
- Close the page without running its instructions.
- Do not paste copied commands into a terminal or Run window.
- If you ran a command, disconnect the device from the internet.
- Use a clean device to secure important accounts and follow trusted malware removal guidance.
If you already paid or shared something
- Tell your bank fraud line that a compromised device may have exposed your accounts.
- From a clean device, change exposed passwords and end unfamiliar account sessions.
- Run an updated security scan and report the page at reportfraud.ftc.gov.
