IT’S A TRAP! Fake CAPTCHA Scams

You’ve probably seen them all over the web—those CAPTCHA challenges asking you to prove you’re not a robot by clicking images or checking a box. CAPTCHAs are supposed to keep websites secure, but cybercriminals are using fake ones to trick users into downloading malware.

This rising scam is especially dangerous for college students, who often use shared networks, laptops, and mobile devices that can become prime targets for hackers.

How the Scam Works

1. You Land on a Fake Site: It might be a pop-up, a sketchy link, or even a spoofed website that looks legitimate.
2. A Fake CAPTCHA Appears: The page claims you need to complete the CAPTCHA to proceed, often accompanied by urgent or misleading language.
3. You’re Asked to Download Something: Instead of solving a CAPTCHA, the site prompts you to download a file or install a browser extension.
4. Malware Is Installed: By following the prompts, you unintentionally install malware, which can steal your personal information or compromise your device.

Why College Students Are at Risk

College students often juggle multiple accounts and devices, making them attractive targets for cybercriminals. These scams can lead to:

• Compromised Accounts: Stolen login credentials for email, banking, or school platforms.
• Data Loss: Malware can corrupt or delete files, including important coursework.
• Identity Theft: Personal information can be used for fraud or sold on the dark web.

How to Protect Yourself

Stay safe by following these tips:

1. Verify the Website: Before interacting with a CAPTCHA, check the URL to ensure it’s legitimate. Look for “https://” and avoid sites with unusual domains.
2. Never Download Files from CAPTCHAs: A legitimate CAPTCHA will never ask you to download software or extensions.
3. Be Wary of Pop-Ups: Avoid clicking on pop-ups that claim urgent action is needed. Close them and navigate away.
4. Use Antivirus Software: Keep your devices secure with up-to-date antivirus tools.
5. Report Suspicious Activity: If you encounter a fake CAPTCHA or malware attempt, report it to the IT Service Desk at (973)655-7971 option 1 or email itservicedesk@montclair.edu.

What to Do If You’re Targeted

If you’ve accidentally downloaded malware:

• Disconnect your device from the internet.
• Run a full scan with antivirus software.
• Change your passwords, starting with your campus accounts.
• Contact the IT Service Desk at (973)655-7971 option 1 or email itservicedesk@montclair.edu.
