(Reuters) - Apple Inc's <AAPL.O> mobile payment system Apple Pay has been hit by a wave of fraudulent transactions using stolen credit-card data from a spate of breaches at retailers, the Wall Street Journal reported, citing people familiar with the matter.
The transactions stemmed from breaches at retail giants including Home Depot Inc <HD.N> and Target Corp <TGT.N>, the Journal reported on Thursday.
The majority of unauthorized purchases have been for big-ticket items bought with smartphones at Apple's own stores, the Journal said.
Apple could not be reached immediately for comment.
