The fake tech support scam arrives in two forms: an unsolicited cold call from someone claiming to work for Microsoft, Apple, or your carrier; or a browser pop-up locking your screen with an "urgent" phone number. Both routes lead to the same trap.
The remote access trap
Once they have your trust, scammers ask you to install a remote-access tool — typically TeamViewer or AnyDesk. With full control of your screen they can access your online banking, steal saved passwords, charge hundreds of euros for a fake repair, or silently install malware.
The rule that never fails
No legitimate tech company — not Microsoft, not Apple, not any French carrier — will ever cold-call you to report a problem on your device. If you receive such a call, hang up immediately. If you see a blocking pop-up, close your browser using Task Manager without dialling the number shown.
If you already gave access
- Cut your internet connection immediately to stop any active remote session.
- Uninstall the remote-access software.
- Change all passwords from a different device.
- Contact your bank and file a police report via service-public.fr.
- Visit cybermalveillance.gouv.fr for tailored support.
