Start with these steps
- Do not call the number in an unexpected pop-up. Close the browser or app if possible. A real security notification should not require you to call a phone number displayed in the warning.
- Do not install remote-access software for an unexpected caller. End the call or chat. Do not share a screen, code, password, or keyboard control.
- Verify through the device or software company’s official support route. Use settings already on the device, a trusted app, or the company website you locate independently.
- Use built-in or trusted security tools. Follow current instructions from the operating system or security provider rather than a tool recommended by the unexpected contact.
- If access already happened, act from a trusted device. Change important passwords, contact affected financial or account providers, and follow official device-security guidance.
Warning signs worth checking
- An unsolicited caller says they are from a well-known technology company.
- A browser pop-up creates noise, locks the screen, or displays a number to call.
- Someone asks you to install remote-control software or read a connection code.
- The supposed technician asks you to sign in to banking, buy gift cards, move money, or pay with cryptocurrency.
- A caller says a refund was too large and asks you to return the difference.
A device can have a real technical problem. The concern is the unexpected contact and unverified route—not every request for technical help.
If someone already accessed the device
- Disconnect the remote session and stop communicating with the person.
- From a different trusted device, change passwords for email, financial, and other important accounts that may have been visible.
- Contact banks or payment providers through official routes if financial information or payments were involved.
- Update security software and run a scan using the device or security provider’s official instructions.
- Review recent account activity and save relevant records privately.
For passwords or identity information, use the personal-information guide. For payments, use the money guide.
