Supermarket giant Tesco has confirmed that hackers were to blame for its website and app going down in a nationwide outage yesterday (October 24).
Concerned shoppers reported being unable to access online services or amend supermarket orders throughout the day, with the disruption continuing into Sunday morning.
Now company bosses have confirmed the outage, which downed its website and app for more than 24 hours, followed an attempt to "interfere" with its systems, reports The Mirror.

Tesco has been inundated with anxious customers unable to arrange deliveries or make changes to their orders.
However a spokesman said there was "no reason" to believe that customer data had been compromised.
A Tesco spokesman told The Mirror this morning: “Since yesterday, we’ve been experiencing disruption to our online grocery website and app.
"An attempt was made to interfere with our systems which has caused problems with the search function on the site.
"We’re working hard to fully restore all services and apologise for the inconvenience.
"There is no reason to believe that this issue impacts customer data and we continue to take ongoing action to make sure all data stays safe.”
Shoppers first reported problems attempting to access the site and app yesterday, and thousands of customers have continued to report problems to DownDetector, which monitors website outages, this morning.
The website issue has left customers unable to make changes to pre-arranged orders.
This morning one irritated shopper posted on Twitter: "I have just had 4 boxes of Pepsi max delivered and no other food as your website has been down for 24 hours and I wasn’t able to edit my basket!!"
Responding to one customer who was trying to amend her order today, Tesco wrote: "Good morning, unfortunately our IT Teams are still working really hard to resolve the issue but we currently don't have any further updates as to when this will be resolved. I am really sorry for any inconvenience caused by this."
Another customer was told shortly after 11am: "We working to resolve the issue as quickly as possible, however, we don't currently know when our app and website will be back up and running."
A tweet pinned to the top of the company's Twitter feed states: "We're experiencing an issue with our website and app and are working hard to get things back up and running. We apologise for any inconvenience."
