How much people are talking about "tech support scam" online, measured by LunarCrush. Attention, not a count of victims.

What it looks like

Pop-up: WARNING. Your computer has been locked due to suspicious activity. Do not close this window. Call Support at 1-800-555-0199 immediately.

Call transcript: "Hello, I'm calling from the Windows security team. Your computer is sending us error messages. I'll help you fix it."

Email: Your protection plan renewed for $399.99. If you did not authorize this, call our billing team at 1-800-555-0123 within 24 hours.

How it works

A scary pop-up, cold call or fake renewal email gets you to call a 'support' number. The technician has you install a remote access app, then shows fake proof of problems. They charge for fake repairs, steal passwords, or open your bank account and claim they 'over-refunded' you so you send money back.

Warning signs

A pop-up with a phone number. Real security warnings do not tell you to call.
An unexpected call about problems with your computer
Asking you to install a remote access app or type a code
Pressure to keep the call secret or stay on the line
Payment by gift card, wire, crypto or a refund you must send back

If you got one of these

Do not call the number. Close the browser. If it will not close, restart the computer.
Hang up on cold calls about your computer. Microsoft and Apple do not call you this way.
If you are worried, contact the company using a number from its official website or your receipt.
Never let a stranger connect to your computer.

If you already paid or shared something

If they connected, disconnect from the internet and remove the remote access app they installed.
From a different device, change passwords for email and banking, and turn on two-step sign-in.
Call your bank or card fraud line to stop payments and ask about disputing the charge.
Report it at reportfraud.ftc.gov. Beware of follow-up calls offering a refund.

Who gets targeted

Often older adults, but anyone who sees a convincing pop-up on a busy day can fall for it.
