The Chinese-language Web site of McDonald's was broken into over Christmas weekend by a hacker protesting its listing of Taiwan as a separate country, the Beijing Youth Daily reported.

McDonald's English-language home page features a sign saying "I'm going to McDonald's" pointing at a drop-down menu listing China and Taiwan as separate "country/market" identities. On Christmas night, the McDonald's Chinese home page was turned into a black-and-white picture of a skull bearing the words "protest McDonald's official Web site listing Taiwan as a country," the newspaper said. On top of the skull were the English words "Chinese hacker." The world's largest restaurant chain has 600 stores in China--its eighth-largest market.
