Camelot says it believes some 26,500 accounts have been accessed, but it has reset passwords and is contacting all of the affected players.
The company said it discovered “suspicious activity” following online security monitoring on Monday.
It is believed “around 26,500 players’ accounts were accessed” , but fewer than 50 have had activity take place since the hack. The Information Commissioner’s Office has launched an investigation into the hack.
“Camelot submitted a breach report to us last night which we have reviewed. We will be talking to Camelot today,” a spokesman for the watchdog said.
They went on to say, “We are currently taking all the necessary steps to fully understand what has happened, but we believe that the email address and password used on the National Lottery website may have been stolen from another website where affected players use the same details.”
“we’d like to reassure our customers that protecting their personal data is of the utmost importance to us. We are sorry for any inconvenience this may have caused our players”
The latest hack follows online breaches affecting Tesco, Yahoo and TalkTalk, among others, within the past two years.
