Tesco

Tesco’s website and app was targeted by cyber attack in October 2021.

Their online grocery store website and app were interrupted.

There have been issues with the site's search feature as a result of an attempt to meddle with their systems.

They apologise for the inconvenience and worked very hard to fully restore all services.
