Navigating the Challenges of Retail Cybersecurity

M&S has been targeted in a cyber attack which has left it unable to process online orders or take contactless payments. Some experts predict it could be costing the company millions of pounds each day.

The notorious hacking group, Scattered Spider is believed to be behind the attack. A cyber security company has told Sky News the group is "one of the most dangerous and active groups" they are monitoring.

There've also been cyber attacks against Harrods and the Co-Op which are being investigated?

On today's Sky News Daily Niall Paterson talks to our science and technology reporter, Mickey Carroll, about Scattered Spider and what can be done to tackle cyber gangs.
