LONDON (Reuters) - British supermarket group Morrisons said on Wednesday that a November cyber attack at technology provider Blue Younder hit its product availability, impacting Christmas sales.
"Our warehouse management system had to be shut down, leaving us without visibility on our fresh and produce stock levels for several days," CEO Rami Baitieh told reporters.
