UK SUPERMARKET CHAIN Tesco is taking reports of a breach in its Clubcard system very seriously and is looking into them.
Sky News reports that 2,000 cards have been cancelled after suspicious activity was uncovered. The card data was shared on a third-party website not operated by Tesco, and since we have a 2,000 number to play with, Tesco is happy to say that only a few punters are involved
In fact, it told Sky that 2,000 accounts have been suspended but it only looks like 10 have been impacted.
"We take the security of our customers' data extremely seriously and are urgently investigating these claims. We are contacting all customers who may have been affected and are committed to ensuring that none of them miss out as a result of this," the company said. "We will issue replacement vouchers to the very small number who are affected."
It appears that common passwords are at fault, and while no Tesco details were plundered, hackers were able to take login details from another website and use them on the supermarket's.
At the BBC, which has seen the list of accounts, customers have been contacted to assess the impact. At least one customer told the reporters that his account had been interfered with. Others acknowledged that their presented login information was correct.
Tesco is not unique in having its customers put in harms way, and recently the US retailer Target said that tens of millions of its visitors were implicated in a massive data heist. µ
