What agents actually hold, and why it’s valuable
Property agencies routinely collect passports and driving licences for anti-money laundering and know-your-customer checks, proof of address, bank account details, mortgage information and tenancy records from buyers, sellers, landlords and tenants. That data has multiple criminal uses: it can be locked up in a ransomware attack until a business pays to regain access, used for identity theft against the individuals affected, or simply sold on the dark web.
