It could be you- as tens of thousands of online lottery Camelot players' accounts are hacked.National Lottery operator Camelot says the login details of thousands of people who do the lottery online have been stolen.

There are 9.5 million national lottery players registered online, but Camelot said only around 26,500 accounts were accessed. It added that fewer than 50 accounts have had suspicious activity, such as personal details being changed, since the breach.

The company said it unearthed “suspicious activity on a very small proportion of our players’ online National Lottery Accounts” during its online security monitoring on 28 November 2016.

It added that there has been no unauthorised access to core systems. “In addition, no money has been deposited or withdrawn from affected player accounts,” said Camelot.

“However, we do believe that this attack may have resulted in some of the personal information that the affected players hold in their online account being accessed.”

The company said it is now trying to find out what happened, but it believes 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”.

The affected accounts have been suspended and Camelot will contact the account holders to re-activate them. Camelot added that it is working with the National Cyber Security Centre on the incident.

Are you an online lottery player?

If so, just crossing your fingers is not enough. To mitigate risks in the short term, account holders should update passwords and avoid using the same password across multiple sites.
