Associate Professor Timofeev: scammers call from numbers consisting of a certain number of digits

Associate Professor of the Department of Informatics of the Russian University of Economics G. V. Plekhanov Alexander Timofeev in an interview with “Prime” pointed out that calls from unfamiliar numbers can be a reason to be wary. He named signs of telephone intruders.

Timofeev noted that not all unknown numbers are dangerous. But here is a call from a too short four-digit number, a hidden number or a number with a foreign prefix, then this is a sure sign that scammers are calling.

Timofeev gave advice: do not call back to such numbers. According to the expert, advertisers usually use toll-free numbers that start with the +7800 code.
