Travel insurance company Staysure has warned customers that they may have had their bank card details stolen following ‘a cyber attack’ during the second half of October 2013.
Up to 93,000 people who bought policies before May 2012 have been warmed that they may be affected.
It is thought that hackers may have accessed the three digit Card Verification Value numbers of some policy holders, according to the company.
In an open letter on its website chief executive Ryan Howsam apologised to customers.
He said: “We are deeply sorry that this has happened and are working diligently to make sure that inconvenience to customers is minimised.”
Those customers at risk have been offered free access to Data Patrol, a comprehensive, identity monitoring service provided by Experian.
Customers who think they may have been affected by the incident can head over to the Staysure website for more information on what to do next.
