Bosses at The Works – which has stores in The Bridges in Sunderland and Middleton Grange in Hartlepool – said that deliveries to stores “are expected to resume imminently” and its normal online service levels are steadily being reintroduced.
In a statement, The Works said: “There has been some limited disruption to trading and business operations, including the closure of some stores due to till issues.
“Customers can continue to shop safely at The Works, both in store and online.
“All debit and credit card payment data are processed securely outside the group’s systems, via accredited third-party networks, and therefore there is no risk that this payment data has been accessed improperly.”
The Works has said that a number of actions have been taken after it was alerted to the breach by its security firewall.
