Tesco customer accounts hacked
Tesco has suspended more than 2,000 online customer accounts after cyber thieves used login details posted on the internet to steal Clubcard vouchers.
A list of thousands of usernames and passwords were posted by hackers on a text-sharing website yesterday.
It is thought the data was taken from other websites in high-profile security breaches and used to access Tesco.com customer accounts to steal Clubcard points, with 2,239 hits where the same usernames and passwords were used.
But only a "handful" of people are understood to have actually suffered theft of their Clubcard vouchers, as secondary security information was needed to fully access the accounts.
Tesco has now deactivated the affected accounts as a precaution and is contacting all customers impacted, pledging to reimburse those who have lost out.
The group said it was "urgently investigating" the security breach.
It added: "We have contacted all customers who may have been affected and are committed to ensuring that none of them miss out as a result of this.
"We will issue replacement vouchers to the very small number who are affected."
