Thousands affected after Tesco.com attack
Login names and passwords for Tesco.com have been shared online.
Tesco has been forced to de-activate some customers' net accounts after their login names and passwords were shared online.
It was reported that there was a list of more than 2,000 Tesco.com accounts that were shared on a well-known text-sharing site by hackers on Thursday.
In a statement, Tesco said: "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 numbers who are affected."
This is not the first time Tesco have been hit by a cyber-attack, as last year many customers revealed their loyalty card details had been breached.
