The UK's largest retailer Tesco has been hacked, compromising the personal details of more than 2,000 of its online customers.

According to a BBC report on Thursday evening, the supermarket has deactivated some customers' Tesco.com accounts after their login details and passwords were shared online.

Some of the affected customers reported that their vouchers had been stolen.

Tesco told the BBC: "We have contacted all customers who may have been affected and are committed to ensuring that none of them miss out as a result of this. We will issue replacement vouchers to the very small number who are affected."

Ian Woosey, senior director at professional services firm Alvarez & Marsal, recently warned the industry that cybercrime needs to move to the top of the retail CEO's agenda. In an exclusive comment piece for Essential Retail, he said that retailers are not paying the necessary attention to e-crime and digital security breaches.

"Most still tend to regard cyber risk as an IT problem and miss the wider business strategy, as well as legal and cultural implications, that protection from cyber attacks requires," he explained.

"Unfortunately, as several major recent breaches show, this is not just an IT problem."

With a number of high profile breaches of retail security in recent months, including Target in the US, Essential Retail will be investigating the issue of retail and cyber-security in more detail next week.
