Mar­riott breach po­ten­tially ex­posed data of 500m guests

Business a.m. - - WORLD BUSINESS & ECONOMY -

MAR­RIOTT INTERNA TIONAL HAS AD MITTED that the per­sonal de­tails of up to 500 mIl­lion guests had po­ten­tially been com­pro­mised since 2014, in what may be one of the big­gest data breaches of its kind.

The world’s largest ho­tel group said its Star­wood Ho­tels & Re­sorts guest reser­va­tion data­base had been ac­cessed un­law­fully. Pay­ment card in­for­ma­tion held on the data­base could also have been taken, Mar­riott said.

Fi­nan­cial Times said shares in Mar­riott fell 7 per cent to $121.84 in pre-mar­ket trad­ing in the US on Fri­day. Mar­riott said that for about 327 mil­lion peo­ple, the ex­posed in­for­ma­tion in­cluded some com­bi­na­tion of their name, mail­ing ad­dress, phone num­ber, pass­port num­ber, Star­wood Pre­ferred guest reser­va­tion num­ber, date of birth and other iden­ti­fy­ing in­for­ma­tion.

Mar­riott said that while pay­ment card num­bers and ex­pi­ra­tion dates held on its data­base were en­crypted, com­po­nents needed to de­crypt this in­for­ma­tion may have been “taken” in the at­tack. “We fell short of what our guests de­serve and what we ex­pect of our­selves,” said Arne Soren­son, Mar­riott’s chief ex­ec­u­tive.
