According to an article by CBC, 40,000 Tesco bank customers' accounts - 20,000 of which had money - were removed.
Over the weekend, customers complained about money withdrawn without permission. They also experienced delays in accessing their account information.
Tesco said any customer hacked would receive a full refund.
Tesco quickly responded to the incident by blocking all online payments for a short period of time to freeze further attempts to steal money. Unfortunately, customers were severely inconvenienced as no accounts could be accessed. This resulted in a slew of frustrated people who could no longer make any transaction.
According to Professor Alan Woodward, a cybersecurity expert, he says
“I've not heard of an attack of this nature and scale on a UK bank where it appears that the bank's central system is the target."

Despite the seriousness of the attack, Tesco has yet to reveal revealed any specific details regarding the intrusion itself. However, there are multiple theories brewing up what could have occurred. These range from a discovery of a vulnerability to a social engineering attack, as well as a few more elaborate ideas. Although, as of now, no further details have been released.
As online banking continues to grow, it's no surprise that the incident was not the first time banks have been targeted by cyber criminals.
The Federal Financial Institutions Examination Council (FFIEC) issued a warning to banks that a group known as “Lazarus Group” pulled off four high-profile digital bank heists. The group managed to steal more than $100 million dollars. At the moment, they remain at large.
Until Tesco issues a formal release with more information about the hacked accounts, the answer will remain unknown.
