Tesco has issued new cards to 600,000 members of its Clubcard loyalty scheme after discovering some accounts had been compromised.
The supermarket chain said attackers attempted to gain access to Clubcard accounts using a database of credentials stolen from other platforms.
Although the hackers were thought to have had some success, no financial information was exposed in the incident and Tescoās systems have not been attacked, the company added.

Fraudulent activity
Tescoās loyalty scheme offers members one point for every pound spent, and every 100 points earned is worth Ā£1 in in-store credit.
Although attackers gained access to the credit accrued by some account holders, Tesco said no Clubcard points will be lost and new vouchers will be issued.
āWe are aware of some fraudulent activity around the redemption of a small proportion of our customersā Clubcard vouchers,ā said a Tesco spokesperson.
āOur internal systems picked this up quickly and we immediately took steps to protect our customers and restrict access to their accounts.ā
According to Chris Miller, Regional Director UK&I at RSA Security, incidents of this kind are exacerbated by usersā reliance on identical log-ins for multiple platforms.
āAuthentication continues to be a balancing act between security and convenience and organisations must continue to look for convenient yet secure ways to make access as easy as possible for the user,ā he told TechRadar Pro.
āFrom the end-userās perspective, it is really important not to use the same password for multiple accountsā¦After all, if attackers have tried to log into Tesco Clubcard with stolen credentials, in all likelihood theyāll be trying the credentials on other sites too.ā
All Clubcard members potentially affected by the incident have been informed via email.
