LONDON (Reuters) -The growth of AI will increase the number and sophistication of cyberattacks on Britain, senior minister Pat McFadden said on Wednesday. British companies, public bodies and institutions have been hit by a wave of cyberattacks in the past few years, costing them tens of millions of pounds and often months of disruption. Over the last three weeks British retailers Marks & Spencer, the Co-op Group and Harrods have all been hit by attacks, with M&S still unable to take online clothing orders.
