Sotheby's International

Sotheby's International, a luxury real estate firm, reported it is investigating a cyber security incident involving unauthorized access to data held in a third-party software platform used to store marketing contact information. The company said the person who accessed the data claimed to have obtained 1.6 million contacts but it refuted that claim because it did not have that many on its database. Regardless of the number, given Sotheby's clientele, even marketing data seems to be a valuable haul from a valuable brand.
