A common request to "let me make a call" can be part of a fraudulent scheme. Senator Artyom Sheikin warned: by getting an unlocked smartphone even for a short time, an attacker can open settings, view messages, or change communication parameters.

The danger is that a phone has long stored more than just a contact list. Banking applications, email, messengers, "Gosuslugi" (State Services portal), and confirmation codes for logging into accounts are linked to it.

One possible scenario is setting up call forwarding. Then calls from banks and services may start going to the fraudster's number, and the owner will not notice the problem immediately. Also, the attacker can check notifications or open the desired application while the device is in their hands.

You can help a stranger more safely: dial the number yourself, turn on the speakerphone, and do not let go of your smartphone. You should not give access to messages, settings, and messengers.

After a suspicious incident, it is better to check call forwarding, active sessions, and the list of connected devices. It is also important to make sure that calls and SMS continue to arrive as usual.
