Tesco’s Chief Customer Officer recently claimed that customers were bigger than marketing, as the retail giant looks to bring back customer confidence after a rocky spell which saw results plummet. One of the ways in which Tesco rewards their customers is with their loyalty scheme. 

Recently, Tesco suffered a security breach which put their 600,000 Clubcard owners at risk of losing important data. The supermarket giant believed that their database containing thousands of usernames and passwords were tried on their website; some may have worked. 

None of the customer’s financial data was accessed and they confirmed that the system had not been hacked. They announced that this a precautionary measure and apologised for the inconvenience.

A statement read: “We are aware of some fraudulent activity around the redemption of a small proportion of our customers' Clubcard vouchers," a Tesco spokesperson said.

"Our internal systems picked this up quickly and we immediately took steps to protect our customers and restrict access to their accounts." 

Tesco have since emailed all clubcard holders to alert them of the issue, as well as reassure them they would resolve the problem and send them new clubcards. 

One of the recipients of the email, Josh, who also works in IT was worried initially after receiving the email. 

"The email was very ambiguous," he said.

"I thought it was because I'd just used a new bank card. I didn't realise it was actually my account details that could have been compromised.

"It worried me - I feel better now it's been clarified."

Others took the new in humorous fashion on social media, joking about how much their clubcard points would be worth to a hacker. 

Jokes’ on the hacker, right?
