As reported by the Public Bureau of the Russian Federation, fraudsters place fake phone numbers of management companies at the entrances. When residents call them, fake service workers receive an accident request, and then offer to "confirm your identity" on the state services portal.
In some cases, the fraudsters also ask for the cadastral number of the apartment - this is how they try to obtain personal data of citizens. Earlier it was reported that the attackers call residents and ask them to provide their passport details, SNILS and date of birth, supposedly to confirm their identity.
