Retailer Nisa has suffered a major leak of its members’ data which has left information including stores’ trading performances and staff details vulnerable.
According to The Sunday Times, the leak was found by an employee, who pointed to a spreadsheet which had been doing the rounds containing shareholders’ addresses, phone numbers and online passwords. It is also believed other sensitive information including stores’ trading performances and staff details have also been left open to access.
Nisa chairman Christopher Baker said that it has launched a “robust” investigation into the alleged data breach.
