Missoma has been the victim of a cyber security heist, confirmed the jewellers in a statement released today.
Affected customers of the brand have all been informed of the data breach via email.
Whilst the company says that the issue is now resolved, personal customer details such as name, address, card number and CVVs could have been compromised.
In a newly released statement, Marisa Hordern, founder of Missoma, said: “We can confirm that our website has been the target of a sophisticated security incident.
“As soon as we became aware of this, we immediately engaged external cyber forensic experts to investigate this criminal activity and alerted the ICO, the Police and Action Fraud.
“The issue has now been resolved.”
She added: “This has only affected a small proportion of our customers, and we have already contacted all customers who may have been affected.
“It is important to note that any customers who have not received an email from us, have no reason to be concerned.
“For those that have received a notification we have given some clear steps on what to do next, including contacting your bank or credit card provider and taking up the free Credit Monitoring we are offering, to further support our customers. These details are all in the individual emails that have been sent out.
“We understand that this is a really busy time for people, and we are incredibly sorry for the inconvenience and concern that this criminal activity may have caused.”
