Leeds United reveal they are tightening their cyber defences after Manchester United was hacked and clubs fear losing millions of pounds if their turnstiles are disabled or valuable transfer data stolen as criminals scale up attacks in the pandemic

Leeds United are tightening their cyber defences in the face of a growing threat from sophisticated criminals, who can extract millions of pounds from the biggest clubs.

English clubs are increasingly concerned about the threat from hackers, who see sport as a 'highly attractive' and 'high-value' target.

In the last year, Manchester United was attacked, an EFL club was hit with a £5m demand and the biggest single loss to a sports organisation from cyber crime was £4m, according to he UK National Cyber Security Centre (NCSC) - part of GCHQ.
