Marks & Spencer : fuite de données clients et perturbations après une cyberattaque
En avril 2025, une cyberattaque a perturbé les paiements sans contact, les commandes en ligne et le retrait en magasin chez Marks & Spencer, qui a suspendu la prise de commandes en ligne. En mai, l’entreprise a révélé une fuite de données clients et estimé le coût de l’attaque à 300 millions de livres sterling. Son bénéfice a ensuite diminué de moitié au premier semestre 2025, tandis que les résultats publiés en novembre 2026 ont montré un redressement du bénéfice après la cyberattaque.
