Hackers claim to have stolen personal data from Pizza Hut customers in a cyberattack they say also netted them information on 30 million orders for Margheritas, Hawaiians and Meat Lover’s products.

The number of Australians who had personal information taken is substantially smaller than the order information claimed: the hacker’s unverified claim was of obtaining data on 1 million people; Pizza Hut said 193,000 were affected.
