Soon after Tesco announced its website and app were running again, but temporarily introduced a “virtual waiting room” to control the high volume of traffic. The attacks that targeted Tesco’s systems were made overnight from a Friday to a Saturday. Still, no further details were announced, with the scale of the issue remaining unclear until Sunday. The lack of information also caused frustration among customers, with many of them wishing to cancel their orders and get a refund. This is not the first time Tesco was targeted. In 2014, almost 2,000 customer accounts were deactivated due to fear of compromised login details, Tesco bank was also hit by a cyberattack. The supermarket’s website seemed to have gone down again last Thursday when shoppers were directed to a “queue” that never seemed to end with the page frequently refreshing itself but never bringing the site back.
