Security News > 2021 > October > Cleanup on aisle C: Tesco app back online after attack led to shopping app outages

The UK's largest retailer, supermarket titan Tesco, has restored its online operations after an attack hack left its customers unable to order, amend, or cancel deliveries for two days.

A Tesco statement acknowledges disruption to the giant's grocery website and app, claiming "An attempt was made to interfere with our systems, which has caused problems with the search function on the site."

Over the past 12 months, Tesco [PDF] more than doubled its regular app user base to 6.6 million and filled 1.27 million orders per week.

Online orders make up 14.6 per cent of Tesco's UK sales.

Earlier this month, The UK appointed former Tesco CEO Sir David Lewis to act as the government's supply chain adviser.

In the wake of this incident, The Register is relieved to know a Tesco exec hasn't been appointed as security adviser.
