An Indian company that operates Marks & Spencer’s IT helpdesk is reportedly investigating whether it was used by cybercriminals to gain access to systems at the retailer, which is battling a devastating hack.

M&S said this week that “threat actors” had gained access to the retailer’s systems through one of its contractors – understood to be Tata Consultancy Services (TCS).
